The identification, development, andpromotion of the most promising methods and materials are primary vehicles for. accelerating advances in repair technology. Working through a variety of forums, ICRI members have the opportunity to address these issues and to directly contribute to improving the practice of concrete repair. A principal component of this effort is to make carefullyselected information on important repair subjects readily accessible to decision makers. During the past several decades, much has been reported in the literature on concrete repair methods and materials as they have 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 . Technical Activities Committee. Each guideline is designed to address a speck area of practice recognized as essential to the achievement of durable repairs. A1IICRI guideline documents are, subject to continual review by the membership and may be revised as approved by the Technical Activities Committee.

In most cases, complete removal" Qf 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 310.1 R-2008 -1 INTERNATIONAL �oa�aaap� CONCRETE REPAIR 1 N S T I T U T E repair cavity is achieved by providing ,a<uniform_. chemical environment around the -reih orcirig- 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 repair may 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 n ionn (Halo) Effect The existing concrete surrounding 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 :canres.iilt in accelerated corrosion of the °siffrouniing 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.

Delaminated concrete can be located using sounding or other suitable techniques. The repair area should extend a minimum of 6 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 corners (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. k Fig. 6.1: Areas of deterioration 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.

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 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 matenals,such as dirt, concrete slurry, and loosely bonded concrete by oil -free, abrasive blasting (Fig. 7.3) or high-pressure water blasting.

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 pulloff strength requirement should be established by the engineer and included as a performance specification for the repair.

Fig. 10.3: Column load path following repair 6 - 310.1 R-2008 GUIDE FOR SURFACE PREPARATION FOR THE REPAIR OF DETERIORATED CONCRETE RESULTING FROM REINFORCING STEEL CORROSION 0 Undercutting of reinforcement is a beSY-prdctide in tensile zones of concrete. 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 fiurther, 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 preparations 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 -tern 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. I>. e INTERNATIONAL �QACHNp' CONCRETE REPAIR I N S T I T U T E 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.

Be sure repair area is not less than 1/8 inch in depth. Preparation work should be done by high pres- sure water blast, scabbler, or other appropriate mechanical means to obtain an exposed aggregate surface With a miniritrrhSufface.profile-of't1./16tn: (CSP-5) Saturate surface with clean water. Substrate should be saturated surface dry (SSD) with no standing water during application. Reinforcing:4teel: Steel reinforcement should be thoroughly prepared by mechanical cleaning to remove all traces of rust. Where corrosion has occurred due to the presence of chlorides, the steel should be high-pressure washed with clean water after mechanical cleaning. For priming of reinforcing steel use Sika® Armate& 110 EpoCem (consult Technical Data Sheet). Concrete Substrate: Prime the prepared substrate with a brush or sprayed applied coat of Sika® Armatec ®110 EpoCem{consult Technical Data Sheet). Alternately, a scrub coat of Sika Top 123 can be applied prior to placement of the mortar. The repair mortar has to be applied into the wet scrub coat before it dries. Pour Component'A into mixing container. Add Component'B'while mixing continuously. Mix mechanically With a low -speed drill (400 - 600 rpm) and mixing paddle or mortar mixer. Mix to a uniform consistency, maximum 3 minutes. Manual mixing can be tolerated only for less than a full unit. Thorough mixing and proper proportion- ing of the two components is necessary. SikaTop® 1:23 PLUS must be scrubbed into the substrate, filling all pores and voids. Force material against edge of repair, working toward center. After filling repair, consolidate, then screed. Material may be applied in multiple lifts. The thickness of each lift, not to be less than 1/8 inch minimum or more than 1.5 inches maximum. Where multiple -lifts are required score top surface of each lift to produce a roughened surface for next lift. Allow preceding lift to reach final set, 30 minutes minimum, before applying fresh material. Saturate surface of the lift with clean Water'. Scrub fresh mortar into preceding lift. Allow mortar or concrete to set to desired stiffness, then finish with wood or sponge float for a smooth surface. inishing As per ACI recommendations for portland cement concrete, curing is required. Moist cure with wet burlap and polyethylene, a fine mist of water or a water based, compatible curing compound. Curing compounds adversely- affect th'P adhesion of following lifts of mortar, leveling mortar or protective coatings. Moist curing should commencei.mmediately after finishing. If necessary protect newly applied material from direct sunlight, Wind, rain and frost. *Pretesting of curing compound is recommended. ■ Applicationthic�ness: Minimum 1/8 inch (3 mm). Maximum in one lift -1.5 in. (38 mm). ■ Minimum ambient and surface temperatures 45"F (7°C) and rising at time of application. in Do not Use solvent -based curing compound. ■ Size, shape and depth of repair must be carefully considered and consistent with practices recommended by ACI. For additional information, contact Technical Service. in For additional information on substrate preparation, referto ICRI Guideline No.03732 Coatings, and Polymer Overlays". ■ If aggressivemeans of substrate preparation is employed, substrate strength should be tested in accordance With ACI 6..03 ARpendix A prior to the repair application. ■ As with alinement based materials, avoid Contact with aluminum to prevent adverse chemical reaction and possible -product failure. Insulate potential areas of contact by coating aluminum bars, rails, posts etc. with an appropriate epoxy such as SikadurO Hi -Mod 32.

Penetrating, corresisn inhibiting, impregnation coating for hardenied concrete How It Works Sika FerroGard 903 is a corrosion inhibiting impregnation coating for hardened concrete surfaces. 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 963 forms a protective layer on the steel surface which inhibits corrosion caused by the presence of chlorides as well as by carbonation of concrete. Sika FerroGard 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 FerroGard 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 FerroGard 903: ■ Steel-reinforcedconcrete, bridges and highways exposed to corrosive environments (deicing salts, weathering) ■ Building faeades and balconies ■ Steel -reinforced concrete in or near a marine environment ■ Parking garages ■ Piers, piles, and concrete dock structures ■ As part of SiM% system approach for buildings and civil engineering structures Advantages Sika FerroGard .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 reinforcedconcrete structure. ■ Protects against the harmful effects of corrosion by penetrating the surface of even the most dense con- crete andA&, sing to the steel to inhibit corrosion. ■ Enhances=the durability of reinforced concrete. ■ Does not require concrete removal. ■ Environmentally sound. ■ Does noVeentain calcium nitrite. ■ Easily applied by either spray or roller to all existing reinforced concrete. ■ Can be:applied to reinforced concrete that already exhibits corrosion. ■ Adds adjtonal benefits when used prior to protective coatings in concrete restoration systems. ■ Water tSas, for easy handling and application. ■ Not a vap;q barrier; allows vapor diffusion. ■ Ferro6ardlas been proven effective in both laboratory (ASTM G109/Cracked Beams) and field analysis. ■ ANSI/NSE'Standard 61 potable water approved Coverage For normal concrete, application is 200 ft 2/gal. each coat. A minimum of two coats is always recommended. For dense=concrete, application may exceed 300 ft?/gal. Therefore, more than two coats may be required to achieve4hie,total application rate: 100 ft.'/gal. Packaging 5 gallon pails with spout, 55 gallon drums. How to Use Surface Preparation Before apply kj4ka FerroGard 903 be sure the surface is clean and sound. Remove all dirt, dust, oil, grease, effioi'escence or existing coatings from concrete surface by steam cleaning, waterblasting or slightly sandblasting. Allow concrete surface to dry prior to application of Sika FerroGard. 903. The dryer the surface - the better the: penetration and effectiveness. �1`r` ,C k G�Citi�irh�itoRrgG p "x r s cs y .,•rrc frosloml hlbitors delay theonset Yf ' S 5 a Y R fg, c^ F) l a 'de�CO �sk �x .

When spraying, use a conven- tional airless 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. Horizontalcsurfaces 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-coi ditions, absorbency of the substrate and maximum recommended moisture content for the subsequently applied system. ■ Minimum arhtiient and substrate temperatures 35°F. ■ Do not-applywhen temperature is expected to fall below 35°F 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. ■ Substrate should be as dry as possible prior to the application. ■ Protectglass, wood, brick, galvanized steel, copper and exposed aluminum during the application. ■ M'aximu, Mchlodde Content of concrete structures intended to be treated with Sika FerroGard 903 is 6 Ibs./y3 (measured�at the level of the reinforcing steel).

Where to Use ■ When diluted, use Sikagard 701 W as a colorless, non -vapor -barrier, water and chloride ion -repellent impregnation for absorbent materials. ■ Treat concrete bridges, roadways, runways, parapet walls, precast, beams, columns, curbing, retaining walls, pavers, etc. ■ Treat both new and existing structures. ■ Treat masonry brickwork, stucco, etc. ■ Porous architectural curtainwall panels. ■ Use on steel -reinforced structures to reduce the corrosion and latent damage potential of chlorides. Advantages Sikagard 701 W is both an economical and simple -to -use sealer. Because of its unique ability to decrease water and chloride intrusion, Sikagard 701 W helps reduce the danger of rebar corrosion. Sikagard 701 W ■ Meets4h. estandards of acceptability for concrete sealers established in NCHRP Report#244. ■ Enhances concrete integrity. ■ Reduces efflorescence. ■ Improves resistance to frost and deicing salts (chloride ion). ■ Reduces dirt penetration. ■ Doesnot act as a vapor barrier. ■ May be. applied to alkaline substrates. Willt notdegrade under UV exposure. Coverage 100-250 sq. ft./gal., (diluted concentrate) depending on porosity of substrate. For proven results against chloride -ion intrusion, 125 sq. ft./gal. is recommended. Packaging 5 gal. pail. A300 How to Use Surface Preparation Before applying Sikagard 701 W, be sure surface is clean and sound. The best impregna- tion is achieved on a dry, very absorbent substrate. Remove all grease, curing compounds, surface treatments, coating, oils, etc. Preparation Work: Concrete. and masonry surfaces, sandblast, high pressure water blast or use other nechanicai means.`` Mixing Dilute Sikagard 701 W concentrate with tap water in an appropriately sized mixing container. Mix with a low speed (400-600 rpm) drill with Sika paddle or comparable drum mixer until uniformly blended. Make sure paddle is completely covered so as not to entrain air. For best results, Sikagard 701 W should be remixed if unused 24 hours after blending with water. Application Apply by roller, brush (horizontal surfaces), or spray. Any pooling of water repellent indicates overdosing on a dense substrate while rapid absorption indicates a porous substrate. Varia- tions in concentration down to 8:1 for dense substrates or coverage area, and/or multiple wet -on -wet applications for porous substrates may be utilized to achieve optimal substrate treatment. Preliminary site test application is recommended to determine effective coverage and performance. Maximum water repellency is generally realized in 72 hours, but may take longer depending on surface and atmospheric conditions. Limitations ■ Adjacent surfaces such -as window frames, glass, stainless steel, aluminum, etc., must be - masked before application. ■ Do not -apply at a temperature below 40°F. ■ Do not: apply when substrate temperature exceeds 120°F. ■ Material is not recommended for below -grade waterproofing. ■ Do not -apply through standing water. ■ Material is not intended to seal visible cracks or crevices from moisture intrusion. ■ Material is not intended for waterproofing under hydrostatic pressure. ■ Performance and penetration depth are dependent upon the surface composition. ■ Do not use on green concrete. ■ When overcoating: an on -site adhesion test is essential to determine actual compatibility. ■ Sikagard 701 W is not a carbonation barrier.

That the concrete deck surface is free of ridges and sharp projections. If metal forms or decks are used they should be ventilated to permit adequate drying of concrete. 2. That the concrete was cured for a minimum of 28 days.(Minimum of 3,000 psi compressive strength). Water -cured treatment of concrete is preferred. The use of concrete curing agents, if any, shall be of the sodium silicate base only; others require written approval by NEOGARD®. r 3. That the concrete was finished by a power or hand steel trowel followed by soft hair broom to obtain light texture or "sidewalk" finish. 4. Thatdamaged areas ofthe concrete deckbe restored to match adjacent areas. Use 70714170715-09 clear 100% solids epoxy and. sand for filling and leveling. 3.2 PREPARATION A. Cleaning: Surfaces contaminated with oil or grease shall be vigorously scrubbed with a stiff bristle broom and a strong non-sudsing detergent such as NEOGARDO 8600 BioDegradable Cleaner. Thoroughly wash, clean, and dry. Areas where oil or other contaminants penetrate deep into the concrete may require removal by mechanical methods. B. Shot -Blasting: Required surface preparation method for remedial construction is also the preferred method for new construction. Mechanically prepare surface by shot-blastingto industry standard surfacetexture (ICRI's CSP3-CSP4) without causing additional surface defects in substrate. Shot-blasting does not remove deep penetrating oils, grease, tar or asphalt stains. Proper cleaning procedures should be followed to ensure proper 04-15-14 07 1813-2 Pedestrian Traffic Coatings bonding of the deck coating. C. AltematetoShot-Blasting:lfshot-blastingis�notpracticd, hydro blasting using minimum 4,000 psi at within 6" of substrate is acceptable."
