Application Instructions Mixing Shake component A and B vigorously before opening. Pour both liquids into a suitable mixing pan and mix for 30 seconds. Add Component C slowly while continuing to stir. Mix mechanically for 3 minutes, using a slow -speed electric stirrer (250 RPM) in order to entrain as little air as possible. Rest for 5 - 10 minutes, until the mixture exhibits a brushable low -dripping consistency. g,'„$> .. nppnwuvu r" Apply a coating of approx. 0.5 �m thick to the cleaned and derusted reinforcement, using a stiff paintbru�' , er or spray gun. Leave to dry for 2 — 3 hours (at an ambient temperature of +20 °C), then apply a second coat of similar thickness. Leave to dry for a similar period of time before applying patching mortar. - It is inevitable that the anti -corrosion coating is applied as well on the surrounding concrete; this is by no means a disadvantage. When used as a binding agent for repair mortar or concrete: Wet down the prepared substrate (concrete) to saturated surface dry condition. Then apply a bonding coat not less than 0.5 mm thick, using a paintbrush, roller or suitable spray gun. For best results, work the bonding slurry well into the substrate to ensure complete coverage of all surface irregularities. Apply the freshly mixed patching mortar wet on wet to the bonding slurry.

The anode consists of a zinc core surrounded by an active cementitious ma- trix. The 63mm diameter x 28mm high embedded anode is quickly and easily fastened to reinforcing steel. Once installed, the zinc core corrodes preferentially to the surrounding rebar, thereby providing galvanic corrosion protec- tion to the reinforcing steel. In the mid 1990s, Vector Corrosion Technologies, through research and development and in partnership with Fos - roc International Limited, a UK company, developed the Galvashield XP embedded anode as a breakthrough in the corrosion protection of concrete structures. The design philosophy behind the Galvashield XP embedded anode was to create a simple product that could be incorporated within a patch repair to minimize ongoing corrosion and extend the life of concrete repairs. Without protection, corrosion continues in the reinforcing steel immediately ad- jacent to the repair and results in premature failure. The anode has been designed to focus protection in the narrow zone directly adjacent to the repair. The size and discrete nature of the anode makes it convenient to install in a wide variety of repairs, and provides the specifier with complete control when targeting the areas that should receive protection. The anode is suitable for large or small repairs; a large repair will simply require the incorporation of multiple anodes. The convenience of the anode makes it a cost effective method of extending galvanic protection to repair scenarios that were not practi- cal just a few years ago. The Galvashield XP embedded anode is a non -hazardous product. Manufactured of common construction materials it is installed simply without complex equipment or processes. Depending upon a project's design parameters the anode will normally operate for a period of 10 to 20 years. Once installed its zinc is converted into a stable, non- hazardous zinc corrosion product. After its service life is complete, the anode remains are dormant and concealed within the concrete, having no maintenance or special disposal requirements. The Galvashield XP embedded anode has been in use in North America since 1998 in a wide variety of applica- tions: deck repairs, joint replacements, pre -stressed and post -tensioned repairs and interface applications between new concrete and existing chloride -contaminated concrete where accelerated corrosion can occur. The anode re- duces on -going corrosion activity and also reduces the effect of ring -anode corrosion commonly associated with concrete patch repairs in reinforced concrete. In order to verify the performance of the Galvashield XP embedded anode, periodic evaluation by various research and education foundations is conducted to provide an unbiased opinion of the effectiveness of this innovative tech- nology. In July 2001, following evaluation of the anode, The Concrete Innovations Appraisal Service issued CIAS Report 01-1 Galvashield Embedded Galvanic Anodes for Repair of Concrete. The principal use of this report is as neutral documentation to help technical committees of the American Concrete Institute (ACI) and users of the an- ode to better understand the technology. As stated in the report "The technology offers an easy -to -understand con- cept, which gives the client confidence in the capability of the repaired structure to perform its intended use." In July 2002, the ASCE/CERF Highway Innovative Technology Evaluation Center (HITEC) commenced evaluation of the Galvashield technology. For many contractors and engineers perhaps the greatest benefit of the Galvashield XP embedded anode is the fact that installation requires little or no change from existing concrete repair practices, and only a minimal addition in cost. Normal patching procedures simply shift the corrosion reaction to adjacent concrete areas, thus creating a continual battle in which repair crews chase the corrosion problem around the structure. The Galvashield XP em- bedded anode prevents this from occurring by mitigating the corrosion problem using a maintenance -free, cost- effective strategy. ® LL u0po"hy Contact: David W.

It was submitted to the voting members of the Association for approval on August 1, 1989. and approved by over 95% of the respondents. Several of thecomments of the voting members, both from those who voted for approval and those who votedagainst approval, are worth noting and are reprinted below, • Even though a guideline exists fordetermining the amountof allowable corrosion before replacing orsupplementitte a rebar, it is always wise to consult a structural engineer if any corrosion exists. • Special caution should be taken to locate and avoid buried electrical conduits orprestressing or post- tensioning tendons when perform- ing removals. Cutting into either can be a life threatening situation. i Undercutting the rebar should not be counted on to secure the repair structurally in lieu of proper methods of bonding a repair to the existing substrate. • A sawcut can and, possibly should, be greater than the 1/2 in. (13 tmn) noted_ as long as the reinforcing steel is not cut into. This document is intended as a voluntary guideline for the owner. design professional and concrete repaircontractor.It is not intended to relieve, the professional engineer or deASner of any responsibility for the specification of concrete repair methods, materials, or practices.

Poston April 1996 GUIDE FOR SELECTING APPLICATION METHODS FORTHE REPAIR OF CONCRETE SURFACES In IR N 0 0 n M Introduction The cause of many concrete repair failures and in- stances of cost overruns can be traced to the selection of inappropriate repair methods. This document has been prepared to help visualize the methods commonly used for the repairof deteriorated concrete surfaces and to survey the applications for which each is'eonsidered to be most suitable. It is not intended to be a detailed and comprehensive "how-to"guide for the various methads described. or p substitute for the recom- mendations of an experienced and qualified repair specialist. This guideline summarizes current practice forplac- ing cement-basedrepair materials. It provides owners, engineers, material suppliers, and repair contractors with a quick reference to assist in the selection of suitable methods of placement. While this guideline, covers only the selection of suitable application meth- ods. other guidelines covering related repair subjects are available from 1CRI. Consistentsuccess in concrete repairbegins with the recognition that each repair situation is defined by a. uniquecombination of circumstances shaped by engi- neering. exposure, constmctibility, cost. and time con- siderations. With this is in mind, users of this guide are encouraged to make the best use of industry resources by bringing the expertise and experience of the engi- neenngcommunny, product manufacturers, and quali- fied contractors into the planning process. Engineering Considerations The installation method mustdetiver the selected repair material to the prepared substrate with predictable results. The properties of repair materials generally specified are compressive strength, bond strength,shear strength, and those properties which influence volume chmiges, such as drying shrinkage, modulus of elastic- ity; andcoefficient of thermal expansion, Other proper- ties such as resistance to freezing and thawing, low permeability, or sulfate resistance may be specified. coMc LTTE P.E4'AM The repair material must fully encapsulate exposed reinforcing steel, achieve satisfactory bond with the substrate, and fill the preparedcavity withoutsegregat- ing. If these requirements are not achieved, the repair will not perform its intended purpose. Bonding of the repair material with the existing substrate depends upon the -repair material reacting with, and interlocking to, the profile of the prepared concrete surface. Some materials may require a bond- ing agent to ensure intimate contact with prepared - surfaces. If the repair material is self -bonding. it must have sufficient binder (e.g. cement paste, epoxy resin) to thoroughly wet our the substrate. Force must be applied to drive the repair material into intimate contact with the prepared surface. The type of force will vary with the application method. In trowel applied systems, the repair material is forced into the prepared surface by the pressure applied to the trowel by the finisher orcement mason. In cast -in -place systems, the pressure is provided by internal vibration, or hydraulic pressure developed by the concrete or Oro pump. High velocity pneumatic placement tech- niques develop exceptional force through impact. The dry packing process generates pressure when the rodding tool pounds the material against the substrate. The requirementthat repair materialsbe mixed and applied without segregating is equally important. Anysegregation of material components will alter physical properties and reduce or negate the ability of the repair to fulfill its. primary function —to- restore the structure to its original condition to the fullest extent possible. Gonstructibility Before finalizing the selection of the repair material and the installation procedure, check the system's constr'uctibility. Todetermine constructibility, the fol.- lowing questions should be addressed: • Can it be built within the constraimsspecfedbYthe engineer and the owner? • Will the specified installation technique allow the repairs to goainm set z.cc within the time specified? �'Nm;�� l y GUIDE FOR SELECTING APPLICATION METHODS FORTHE REPAIR OF CONCRETE SURFACES 03731.1 ft a 94rcSilyo CONCRETE FEDAJR N • Is the working environment conducive to the speci- fied installation- technique? • Are experienced contractors available for the project? If the answer to any of these: questions is no or maybe, then the choice of repair material and installation method should be reassessed. Selection The selection of a suitable repair material and applica- tion method should proceed inthissequence_ 1 Select the repair material providing the strength and durability properties whichbect restore the integrity of the original design.. 2 Select a method of placement which will success- fully place the repair material onto the prepared concrete. 3 Review the physical properties and placement re- quirements for the repair material to ensure the constructibility of the selected repair system. 4 Change the material orapplicationmethodasneeded to provide a constructible repair. When trade-offs needto be ani&-the long-termdumbility, of the repair system is far more important than the ease of application. Quality Assurance and Quality Control The combination of the working conditions. the repair contractor, theexisting concrete material. the structure design, and the repair material. is unique to every project. Much can go wrong without proper quality assurance and routine quality control. Start by selecting a qualified contractor who can demonstrate successful long-term repairsrising the intended ins tallationmethod. If any questions remain unanswered regarding the contractor's qualifications, the repair material, or the installation technique, consider a pilot project. During the actual repairs. develop a feedback sys- tem to verify compliance with the engineering require- ments established for the project. Physical properties of the materials can he confirmed by sampling at the time of placement, by in -place testing. or by using core sampling techniques. Bond strengths can be verified by coring through the repair and into the substrate. fol- lowed by applyinga tensile force to the core.! 11 Consoli- dation of the materials can be verified with visual observations of extracted cores and in -place testing.

Material requirements: Pumpabic, good flaw chuac- teristics,setf-bonding, aggregate size compatible with size of cavity and space between bars. Reference: Ad 304.211. "placing Concrete by Pump- ,,,m ins Methods-' Preplaced aggregate General description: Gap -graded aggregate is placed into formed cavity. Grout is thenrumped into form via grout pump until all voids :ue filled and pressurized. Shrinkage is minimal because of aggregate contact and volume. Best application: Vertical and overhead applications where extremely low shrinkage of repair material is required; column enlargements. Material requirements: Gap -graded aaaregatc (40- 50`.'o void ratio). pumpable grout, self -bonding Port- land cement or resin -based binder. One inch (.25 mm) or larger aggregate typically used in cementitious applications..
