Observations of the initial demolition will determine any required modifications to the above procedures and materials selected for the final restoration process. Based on initial visual observations, repairs will not require shoring; however, in the event the demolition work reveals that shoring will be required, the engineer will instruct the contractor to shore the area as well as the number of levels required. The instructions given to the contractor will be submitted to the Building Department with the final close-out documents. We have been authorized by the Association to work with the contractor during the restoration and, will inspect work partially completed as well as observe results of the new demolition prior to field authorizing the repairs to be completed. The proposed concrete restoration work, except as authorized by the engineer's modified instructions, will comply with specifications outlined in the IRCI Guideline No. 03730, as well as the applicable minimum building codes and the applicable fire safety standards as determined by the local authority in accordance with Chapter 553 and Chapter 633 of the Florida Statutes where applicable to concrete restoration.

It is designed to penetrate the surface and then to diffuse in vapor or liquid form to the steel reinforcing bars embedded in the concrete. Sika FerroGard 903 forms a protective layer on the steel surface which inhibits corrosion caused by the presence of chlorides as well as by carbonation of concrete. How it Works Sika FenoGard 903 is a combination of amino alcohols, and organic and inorganic inhibitors that protects both the anodic and cathodic parts of the corrosion cell. This dual action effect dramatically delays the initia- tion of corrosion and greatly reduces the overall corrosion activity. Sika FenoGard 903 protects the embedded steel by depositing a physical barrier in the form of a protective layer on the surface of the steel reinforcement. This barrier inhibits corrosion of the steel. Where to use Sika FerroGard 903 is recommended for all steel -reinforced, prestressed, precast, post tensioned or marine concrete. Use of Sika FenoGard 903: ■ Steekeinforced concrete, bridges and highways exposed to corrosive environments (deicing salts, weathering) • Building facades and balconies ■ Steel -reinforced concrete in or near a marine environment in Parking garages ■ Piers, piles, and concrete dock structures • As part of Sika's system approach for buildings and civil engineering structures Advantages Sika FeroGard 903 offers owners, specifiers, port authorities, DOTS, and engineers, a new technology in corrosion inhibition that can easily be applied to the surface of existing concrete to extend the service life of any reinforced concrete structure. iii Protects against the harmful effects of corrosion by penetrating the surface of even the most dense con- crete and diffusing to the steel to inhibit corrosion. ■ Enhances the durability of reinforced concrete. • Does not require concrete removal. iii Environmentally sound. ■ Does not contain calcium nitrite. iii Easily applied by either spray or roller to all existing reinforced concrete. iii Can be applied to reinforced concrete that already exhibits corrosion. ■ Adds additional benefits when used prior to protective coatings in concrete restoration systems. iii Water based for easy handling and application. ■ Not a vapor barrier,, allows vapor diffusion. • FerroGard has been proven effective in both laboratory (ASTM G109/Cracked Beams) and field analysis. • ANSIINSF Standard 61 potable water approved Coverage For normal concrete, application is 200 f .2/gal. each coat. A minimum of two coats is always recommended. For dense concrete, application may exceed 300 R.'/gal. Therefore, more than two coats may be required to achieve the total application rate: 100 fL'Igal. Packaging 5 gallon pails with spout, 55 gallon drums. AND EQUIPMENT,` CONDITIONS.'.: nc discoid. How to Use Surface Preparation Before applying Sika FerroGard 903 be sure the surface is clean and sound. Remove all dirt, dust, oil, grease, efflorescence or existing coatings from concrete surface by steam cleaning, waterblasting or slightly ® sandblasting. Allow concrete surface to dry prior to application of Sika FeroGard 903. The dryer the surface ® the betterthe penetration and effectiveness. t 'Kay, Cnterla , Pertormance Lav¢I , - Test Method/Institute Conosion mhiblbon FerroGard lohibdors tlaIIs' a onset - 11 "I'llcorrosion of comasi8n,and reduce the rate of corrosion 1 _ by,9S l6 vsmus cant , I specimen after 1 year., _ - Penetratlon Raba In hardened FerroGard 903 penetrates independently of - concrete onentetign (hdnzortai, vgTBcal, averhee'd) at a 2 rota.of;1h70to4(5,Ihches-(2.bfo2Omm)per, - - , Willg;othdnsoft ,day;,deperdine'.: Depth of Penetration _ FerroGard 903 penetates up to 3 Inches 2 (76rtim)in 28 days - - Protedrve layeron steel - FerroGard 903 forms a;prote&rJe,layeron the;- reinforung steel ofhigbSntegn`tydneasur`ed at '3 - as muctj-eslgp A)n thioRness , Dlsplacermintof ehlondes from FerroGard 903 forms a continuous film on the' Steel surface .< reinforcing steel and displaceschlonde fons ,3 -,from.the steel surtace: -, ' Corrosion Rate Field Monttofmg?>Reduchon of corrosion rates in excess of 65h.

When spraying, use a conven- tional aidess spray system or hand -pressure equipment. A minimum of two coats is always recommend- ed. Dense substrates may require more coats. Waiting time between coats of Sika FerroGard 903 is at least 1 hour. Allow a minimum of one day to allow Sika FerroGard 903 to dry and penetrate. ' When Sika FerroGard 903 is used prior to the application of a repair mortar, concrete overlay, protective coating, Sikafloor system or any other application, care must be taken to remove any residue remaining on the surface from the application of Sika FerroGard 903. Clean the substrate in such a manner (i.e. push the water in one direction away and off from the surface to be overcoated) to Completely remove any residue. Horizontal surfaces require pressure washing (2,000 psi minimum) to remove the residue. Vertical surfaces may be rinsed with water or pressure washed. The use of Sika Armatec 110 EpoCem as a bonding agent prior to the application of repair mortars or concrete overlays is suggested. Drying times depend on envi- ronmental conditions, absorbency of the substrate and maximum recommended moisture content for the subsequently applied system. - ■ Minimum ambient and substrate temperatures 35°F. . Do not apply when temperature is expected to fall below 357 within 12 hours. . If the applied surfaces will be submerged after the application of Sika FerroGard 903, a waterproofing coating must be applied prior to submersion. Ni Substrate should be as dry as possible prior to the application. In Protect glass, wood, brick, galvanized steel, copper and exposed aluminum during the application. . Maximum chloride content of concrete structures intended to be treated with Sika FerroGard 903 is 61bs./y3 (measured at the level of the reinforcing steel). For levels up to 10 lbs./ya, consult technical service. Irritant -Skin and eye irritant. Vapors may cause respiratory tract irritation. Use only with adequate ventila- tion. Use of safety goggles and chemical resistant gloves is recommended. Remove contaminated cloth - In case of skin contact, wash thoroughly with soap and water.

The substrate must be saturated surface -dry (SSD) with no standing water. 2. Flextight" is applied only to the positive side (source of moisture) of the substrate in 1 or 2 void - free coats. Allow 24 hours before second coat. Thoroughly work the material into the substrate. Make sure the rounded edges are fully coated. Apply at 80 wet mils, using a 1/8" (3 ram) square -notched trowel, yielding 60 dry mils (1/16" or 1.6 mm). 3. Embed fiberglass tape wherever dissimilar materials join. Also treat surface cracks less than 1/8" (3 mm) wide and areas where underlayment panels meet. 4. In most cases,1 coat is sufficient Without reinforcing mesh. If reinforcement is necessary, embed an appropriate mesh into the still -wet first coat and use a trowel to work the material up and through the mesh until it is completely embedded. Material that is too thick is subject to drying or shrinkage cracking. Be certain to cover all reinforcement material. 5. Smooth over with the flat trowel edge, creating a smooth, void -free membrane. Curing Time 1. Prevent premature drying of the green application and protect it from extreme heat, direct sunlight, wind, rain, and frost for at least 3 days. (Curing time varies with humidity, temperature, and substrate porosity.) 2. Tile can be applied after 3 days. 3. Do not allow surface to become wet before curing is complete. Protection boards may be needed to avoid puncturing membrane while installing tile. Clean Up Wash tools with water immediately after use. Cured material may only be removed mechanically. For Best Performance • Do not apply at temperatures below 400 F (40 C) or above 900 F (320 Q. • Do not dilute with water. • Do not use additives of any kind. • Do not apply thicker than 1/16" (1.6 mm). • Do not over trowel. • Use caution under extremely hot or windy conditions; they will shorten the pot life and reduce trowelability.

SURFACE PREPARATION CONCRETE 1.Concrete must be fully cured (28 days), structurally sound, clean and dry (ASTM D 4263). All concrete surfaces (new and old) must be shot blasted to remove previous coatings, laitance and all miscellaneous surface contamination and to provide profile for proper adhesion. Abrasive shot blasting must occur after concrete repair has taken place. Acid - etching is not permitted. Proper profile should be a minimum of ]CHI CSP-3 (as described in ICRI document 03732.) SURFACE PRE -STRIPING AND DETAILING t.For nonmoving joints and cracks less than Y,6" (1.6 mm) wide, apply primer when required, followed by 25 wet mils (0.6 mm) pre -striping of MasterSeal M 200. MasterSeal M 200 must be applied to fill and overlap the joint or crack 3" (76 mm) on each side. Feather the edges. 2.Dynamic cracks and joints As" (1.6 mm) and greater wide must be routed to a minimum of Ya by'/4" (6 by 6 mm) and cleaned. Install bond breaker tape to prevent adhesion of sealants to the bottom of joint. Prime joint faces only with MasterSeal P 173 (see Form No. 1017962). Fill joints deeper than %" (6 mm) with appropriate backer rod and MasterSeal SL 1-/SL 2' (slope grade or self -leveling) or MasterSeal NP 1-/NP 1'" sealants (see Form Nos.1017903 and 1017911). For cracks, sealant should be flush with the adjacent concrete surface. For expansion joints, sealant should be slightly concave. 3.Sealed joints 1" (25 mm) or less can be coated over with MasterSeal Traffic 1500. Expansion joints exceeding 1" (25 mm) wide should not be coated over with MasterSeal Traffic 1500 so that they can perform independently of the deck coating system. Techacal Data Guide MasterSeal* Traffic 1500 4.Cut a ll/a by 1/4" (6 by 6 mm) keyway Into the concrete where the coating system will be terminated If no wall, joint, or other appropriate break exists. Fill according to Instructions on cracks and joints over1l/t6" (1.6 mm) wide. R.Form a sealant cant into the corner at the junction of all horizontal and vertical surfaces (wall sections, curbs, columns). Prime with MasterSeal P 173 and apply a Y2-1" (13-25 Turn) wide bead of MasterSeal NP1 or MasterSeal NP 2 sealants. Tool to farm a 450 cant. e.ln locations of potential high movement, such as wall and slab intersections, apply 25 wet mils (0.6 rem) of MasterSeal M 200 and embed MasterSeal 955. METALSURFACES I.Remove dust, debris, and any other contaminants from vent, drain -pipe and post penetrations, reglets and other metal surfaces. 2.Clean these surfaces to bright metal and prime immediately with MasterSeal P 173. a.Provide appropriate cant with MasterSeal NP 1, NP 2 or OR 195 sealant to eliminate 900 angles. PLYWOOD 1.AII plywood must be smooth -faced, APA- stamped and exterior grade. Construction must conform to code, but plywood must not be less than 11/62" (12 mm) thick. Plywood spacing and deck construction must follow APA guidelines. 2.Surfaces must be free of contaminants. Priming is not necessary on clean, dry plywood. a.All seams must be caulked with MasterSeal NP 1 or MasterSeal NP 2 sealants (see Form Nos.1017906 and 1017911). Pre -stripe 4-6" (102-152 mm) wide with 25 wet mils (0.6 mm) of M 200. Reinforce all seams between plywood sheets and between flashing and the plywood deck by embedding MasterSeal995 into the pre-srping. APPLICATION OF PRIMER PRIMER NOTE: When primer is required on a job, follow these steps. When applying Traffic 1500 without using a primer, proceed to Application. 1.After thoroughly vacuuming the surface, apply MasterSeal P 222 or P 220 to all the properly prepared deck surfaces at the rate of 200-250 fta/gal (4.9-6.1 m'/L). Using a roller pan and a short- to medium -nap roller cover, force the primer into pores and voids to eliminate pinholes. Do not apply over pre -striping. Use only solvent -resistant tools and equipment. 2.Allow primer to dry until tack -free. M 200 must be applied the same working day. MASTERSEAL M 200 1.AII preparatory work must be completed before application begins. Be certain the substrate is clean, dry, stable and property profiled. Sealants and pre -striping should be properly cured. Apply the base, mid and finish coats with a properly sized squeegee to arrive at the required mil thicknesses. 2.The best method to ensure the proper wet film thickness is the use of a grid system. Divide the surface to be coated Into grids and calculate the square footage of each. Refer to the coverage chart to determine the quantity of MasterSeal Traffic 1500 needed for each grid to arrive at the required mil thicknesses. For example, one pail of MasterSeal M 200 will cover an area approximately 300 it' (28 of ), or a grid 30 by 10 ft (9 by 3 m) at 25 wet mils (0.6 m ni The mil thickness of all coats can also be verified by the use of a wet -mil thickness gauge. a.Apply MasterSeal M 200 25 wet Tills thick (0.6 mm) using a proper notched squeegee to entire deck surface, and back roll, overcoating the properly prepared cracks, joints and flashings. For sloped areas, use slope -grade MasterSeal M 200. Do not coat expansion joints over 1" (25 mm) wide. 4.Allow curing time of overnight It hour minimum). Slightly extend the curing time in cool or dry weather conditions. The surface of MasterSeal M 200 should have a slight tack. If the coating has been exposed for a prolonged period, consult Technical Service for recommendations. APPLICATION METHODS OF SYSTEMS MasterSeal Traffic 1500 can be installed in several configurations, depending upon the degree of traffic to which the system is exposed. In areas of extreme traffic (turning lanes, pay booths, entrances and exits), apply the Extra Heavy -Duty Traffic System. The following summary briefly describes each configuration.

During the past several decades, much has been reported in the literature on concrete repair methods and materials as theyhave been developed and refined Nevertheless, it has been difficult to find critically reviewed information on the state of the art condensed into easy -to -use formats. To that end, ICRI guidelines are prepared by sanctioned task groups and approved by the ICRI TechnicalActivities Committee. Each guideline is designed to address a speck area of practice recognized as essential to the achievement of durable repairs. Al1ICR1 guideline documents are subject to continualreview by the membership and may be revised as approved by the Technical Activities Committee.

This guideline outlines removal geometry, configuration, removal process, edge preparation, reinforcement repair, surface preparation, and inspection prior to placing a repair material. An engineer should evaluate the impact of concrete removal on structural capacity prior to performing concrete removal and repair. The repair methods involve saw cutting and concrete removal using impact tools, hydrodemolition, and other removal techniques. Special caution should be taken to locate and avoid cutting or damaging embedded reinforcing bars, prestressing strands, post - tensioning tendons, or electrical conduits. Cutting into these items can be life threatening and may significantly affect structural integrity. This guideline also contains a discussion of concrete removal and preparation for the repair of columns where the concrete is in compression. Special consideration must be given to the repair of concrete in compression as the load -carrying capacity of the element may be permanently compromised during the concrete removal and preparation process. While the procedures outlined herein have been used to successfully remove concrete and prepare the removal cavity on many projects, the requirements for each project will vary due to many different factors. Each project should be evaluated individually to ascertain the applicability of the procedures described herein. Refer to ACI 506R-05, "Guide to Shotcrete" for surface prepar- ation prior to shotcrete application. 2.0 Definitions Anodic ring effect: Corrosion process in which the steel reinforcement in the concrete surrounding a repaired area begins to corrode preferentially to the steel reinforcement in the newly repaired area (sometimes referred to as the halo effect). Bruised surface (micro -fracturing): A surface layer weakened by interconnected microcracks in concrete substrates caused by the use of high - impact, mechanical methods for concrete removal, and surface preparation; fractured layer INTERNATIONAL glt;It16- CONCRETE REPAIR i%ftiw� I N S T I T U T E typically extends to a depth of 0.13 to 0.38 in. (3 to 10 mm) and, if not removed, frequently results in lower bond strengths as compared with surfaces prepared with nonimpact methods. Carbonation: The conversion of calcium ions in hardened cementitious materials to calcium carbonate by reaction with atmospheric carbon dioxide. Carbonation reduces the pH of the concrete and its ability to protect reinforcing steel and embedded metal items from corrosion. Chloride contamination: Contamination of concrete with chloride ions commonly used in deicing salts and accelerating admixtures such as calcium chloride and sodium chloride. Chloride contamination above the threshold for corrosion can result in corrosion of the reinforcing steel. Chloride threshold: The amount of chloride required to initiate steel corrosion in reinforced concrete under a given set of exposure conditions; commonly expressed in percent of chloride ion by mass of cement. Corrosion: Degradation of concrete or steel reinforcement caused by electrochemical or chemical attack. Microcrack: A crack too small to be seen with the unaided eye. Tensile pulloff test: A test to determine the unit stress, applied in direct tension, required to separate a hardened repair material from the existing concrete substrate. The test may also be used to determine the maximum unit stress that the existing concrete substrate is capable of resisting under axial tensile loading and the near - surface tensile strength of a prepared surface (refer to ICRI Technical Guideline No. 210.3- 2004 (formerly No. 037391 and ASTM C1583). Substrate: The layer immediately under a layer of different material to which it is typically bonded; an existing concrete surface that receives an overlay, partial -depth repair, protective coating, or some other maintenance or repair procedure. 3.0 Exposure of Reinforcing Steel The practice of completely removing the concrete (undercutting) from around the corroded reinforcement, no matter what degree ofcorrosion is found, is key to achieving long-term performance of surface repairs. In most cases, complete removal of the concrete from around the reinforcing steel is the best practice, where protection of the reinforcing steel within the GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REINFORCING STEEL CORROSION 310.111-2008-1 .> Y I �INNT [RNATIONAL S T Clt➢ NI REPAIR T I T U T E repair cavity is achieved by providing a uniform chemical environment around the reinforcing steel. If noncorroded reinforcing steel is exposed and the concrete is chloride contaminated, removal of the concrete around the reinforcing should occur or other corrosion -reducing means should be considered. Reinforcing steel partially embedded in chloride -contaminated concrete is susceptible to future accelerated corrosion. If, for structural reasons, the concrete cannot be completely removed from around the corroded reinforcing steel or if a corrosion inhibiting system is not used, the repairmay be compromised due to continued corrosion. If there is a potential trade-off between durability and structural capacity, structural capacity should always take priority. When reinforcing steel is not fully exposed through the concrete removal and preparation process, alternative corrosion inhib- iting systems should be considered. These systems may include use of corrosion inhibitors, sacrificial anodes, or cathodic protection. 4.0 Anodic Ring (Halo) Effect The existing concretesurrounding a repair area in chloride -contaminated or low pH reinforced concrete is susceptible to accelerated corrosion. This is due to the electrical potential differential between the chloride contaminated or low pH existing concrete and the chloride -free or high pH repair material. This anodic ring effect can result in accelerated corrosion of the surrounding reinforcing steel leading to future concrete deterioration. To assess existing concrete conditions beyond the repair area, chloride content and pH of the concrete at the level of the reinforcing steel should be determined. Where the chloride content exceeds the threshold level for the initiation of corrosion or where the reinforcing steel is susceptible to corrosion as a result of carbonation, a corrosion inhibiting system should be considered to minimize future corrosion. Other measures may also be considered, such as the application of sealers and coatings, to slow the corrosion process. In severely chloride - contaminated or carbonated concrete, the complete removal and replacement of the contaminated concrete at and beyond the repair area may be necessary to provide a successful long-term repair. 5.0 Removal Geometry Examples of the removal geometry for several different types of reinforced concrete elements are shown in Fig. 5.1 through 5.6. Repairs may be located on horizontal, vertical, and/or overhead surfaces. The removal in Fig. 5.5 and 5.6 is for columns where the removal will not affect the structural capacity of the column. Removal of concrete within the reinforcing or to expose the reinforcing (concrete in compression) is a special condition and is discussed in Section 10.

Column repair, section ��INTL-RNATIONAL CaQCIQQ� CONCRETE REPAIR INSTITUTE Y® 6.0 Configuration of Repair Area Deteriorated and delaminated concrete should be located and marked prior to starting the removal process. Delaminated concrete can be located using sounding or other suitable techniques. The repair area should extend a minimum of in. (152 mm) beyond the actual delaminated concrete. Note that during concrete removal, repair areas can grow in size beyond the areas identified due to incipient delaminations that are not readily identifiable by sounding. Repair configurations should be kept as simple as possible, preferably square or rectangular with square comers (Fig. 6.1). This may result in the removal of sound concrete. Reentrant corners should be minimized or avoided, as they are susceptible to cracking. Uo Fig. 6.]: Areas ofdeterioration and recommended removal configurations 7.0 Concrete Removal/Surface Preparation 7.1 Exposing and Undercutting of Reinforcing Steel Remove concrete from the marked areas and undercut exposed reinforcing steel (Fig. 7.1) using impact breakers, hydrodemolition, or another suitable method. Undercutting will provide clearance under the reinforcing steel for cleaning and full bar circumference bonding to the repair material and the surrounding concrete.

CONCRETE U T E i��®�yf� I N S T I T U T E the repair material to the full circumference of the reinforcing steel will secure the repair structurally. Provide a minimum of 0.75 in. (19 mm) clearance between exposed reinforcing steel and surrounding concrete or 0.25 in. (6 mm) larger than the coarse aggregate in the repair material, whichever is greater. Sound concrete may have to be removed to provide proper clearance around the reinforcing steel. If impact breakers are used for partial depth concrete removal, the breaker should not exceed 30 lb (12 kg). A 15 lb (7 kg) breaker is preferred Fig. 7.1: Remove concrete to undercut and expose reinforcing steel and provide uniform repair depth Fig. 7.2: Saw cut perimeter to provide vertical edge Fig. 7.3: Abrasive blasting to clean substrate and reinforcing to minimize damage to the substrate, reinforcing steel, and surrounding concrete. Concrete removal should extend along the reinforcing steel until there is no further delsm- ination, cracking, or significant corrosion and the reinforcing steel is well bonded to the surrounding concrete. Care should be taken to avoid significant and sudden changes in the depth of concrete removal, as the repair material is more susceptible to cracking at these locations. If noncorroded reinforcing steel is exposed during the removal process, care should be taken to not damage the bond to the surrounding concrete. If the bond between the reinforcing steel and concrete is broken, undercutting of the reinforcing steel is required. Remove all deteriorated concrete and additional concrete as required to provide the proper configuration and/or the minimum required thickness of repair material as required by the manufacturer of the repair material and/or the project specifications. 7.2 Preparation of. the Repair Perimeter The perimeter of the repair area should be saw cut 0.75 in. (19 mm) deep to provide a vertical edge (Fig. 7.2) for the repair material. This will avoid featheredging of the repair material. Depending on the repair material selected, the depth of the existing reinforcing and the manufacturer's recommendations, a saw cut depth less than 0.75 in. (19 mm) deep may be sufficient. Care should be taken to avoid cutting the existing reinforcing steel. 7.3 Cleaning of the Concrete Surface and Reinforcing Steel The use of high -impact, mechanical methods to remove deteriorated concrete will result in a surface layer weakened by interconnected micro - cracks in the concrete substrate. The fractured (bruised) layer can extend to a depth of 0.125 to 0.375 in. (3 to 10 mm) into the resultant concrete substrate and may result in reduced bond strength. Remove the bruised layer and bond -inhibiting materials such as dirt, concrete slurry, and loosely bonded concrete by oil -free abrasive blasting (Fig. 7.3) or high-pressure water blasting. The 4 - 310.1 R-2008 GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REINFORCING STEEL CORROSION saw -cut edge of the repair area should also be blasted to roughen the polished vertical surface caused by the saw -cutting. All concrete, corrosion products, and scale should be removed from the reinforcing steel by oil -free abrasive blasting or high-pressure water blasting. Verify that the reinforcing steel and concrete surface are free from dirt, oil, cement fines (slurry), or any material that may interfere with the bond of the repair material. Inspect the repair cavity to verify that all delaminations and deterioration have been removed. If hydro - demolition is used, cement fines (slurry) must be completely removed from the repair surface. A tightly -bonded light rustbuild-up on the reinforcing surface is usually not detrimental to bond. If a protective coating is applied to the reinforcing steel, follow the coating manufacturer's recom- mendations for steel surface preparation. 8.0 Inspection and Repair of Reinforcing Steel Loose reinforcement should be secured in its original position by tying to secure bars or by other appropriate methods to prevent movement during placement of repair material. If reinforcing steel has lost cross -sectional area, a structural engineer should be consulted. Repair reinforcing steel by either replacing the r as % INTERNATIONAL ZIF I NSTITUTE damaged/deteriorated steel or placing supple- mental reinforcing steel in the affected section (Fig. 8.1). Supplemental reinforcing steel may be lap -spliced or mechanically spliced to existing reinforcing steel. The supplemental reinforcing steel should extend (lap length) beyond the damaged/deteriorated area in accordance with ACI 318, "Building Code Requirements for Structural Concrete." 9.0 Final Surface Inspection Immediately prior to placing the repair material, inspect the repair cavity to verify that all bond - inhibiting materials (dirt, concrete slurry, loosely bonded aggregates, or any material that may interfere with the bond ofthe repair material to the existing concrete) have been removed. If bond - inhibiting materials are present, the repair cavity should be recleaned as previously described. To verify the adequacy of the prepared concrete surface and completeness of bond - inhibiting material removal, a tensile pullofftest (ICRI Technical Guideline No. 210.3 2004 or ASTM C1583) should be considered to evaluate the bond strength capacity and tensile strength of the existing concrete substrate. This test may also be performed after the repair is complete. The pulloffstrength requirement should be established by the engineer and included as a performance specification for the repair.

In columns, the primary loading condition is compression. From a design perspective, the concrete section contained within the reinforcing cage is considered to carry the compressive loads (Fig. 10.1). The concrete outside ofthe reinforcement is considered as protective concrete cover for fire and corrosion protection of the reinforcement. Removing the concrete within the column reinforcing steel (Fig. 10.2) can greatly increase the compressive stress in the reinforcing steel and the remaining concrete. Upon concrete removal, compressive load paths redistribute around the repair (deteriorated) sections (Fig.10.3). Depending on the size of the concrete removal area behind the column steel, buckling of the column vertical reinforcing bars can occur. In the majority of cases, shoring systems will not unload the compressive stress in the column section. When new repair material is placed in the prepared area, the new material cures and most materials undergo drying shrinkage, which results in the new material being put into a tensile stress state. The new material will not carry compressive loads until the original concrete compresses further, forcing the repair material into compression. If further compression is beyond the capacity of the existing concrete, failure of the column may occur. This key concept affects the concrete preparation process. In normal concrete repair (other than columns), removal of the concrete surrounding the corroding reinforcement (also known as undercutting) is a normal and necessary process to provide for a long -tens durable repair. To remove concrete around vertical reinforcing steel in a column (removing concrete inside the reinforcing bar cage) can cause the remaining concrete and/or reinforcement in the column to become overstressed. From a structural point of view, this condition may not be desirable. If concrete is to be removed inside the reinforcement cage, a qualified structural engineer should determine the impact of the repair on potential reinforcement buckling and overall structural capacity of the column. Note that the discussion in this section is also applicable in concept to compression zone portions of other structural members such as beams, slabs, and walls (with or without compression reinforcement) where on -going compressive stress exists and where adequate shoring cannot be installed prior to repairs to prevent displacements and corresponding stress redistributions during repairs. 11.0 Summary The repair of deteriorated concrete resulting from reinforcing steel corrosion is necessary to extend the service life of the structure. Performing concrete repairs using industry -best practices will ensure the success and longevity of the repair. Understanding the existing conditions and cause of corrosion will assist the engineer in specifying the type and extent of the repair required, and the type of corrosion mitigation systems and/or preventative measures that should be considered to protect the structure from future deterioration. 12.0 References 12.1 Referenced Standards and Reports The following standards and reports were the latest editions at the time this document was prepared.
