| 25 | Provide and install sacrificial zinc anodes to prevent initiation of corrosion of steel reinforcement in chloride-contaminated or carbonated concrete or new construction. Zinc mass should be a minimum. 60 g/unit or More, and the zinc surface area and spacing of anodes should be selected/designed in a way to achieve the target service life of 10 years. The quality of zinc should be in compliance with ASTM B418-95a, Type I, die-cast around steel tie-wires (in case of more than one tie wire, they should be well separated) and encased in a highly alkaline cementitious mortar (encapsulating mortar) with a pH of 14 or greater. The encapsulating mortar should not have sulphates, chlorides, bromides, or any other elements corrosive to steel. The encapsulating mortar should have an interconnected and fine pore structure to dissolve, transport, and accommodate zinc corrosion products away from the zinc surface without causing additional stress to the cover concrete, and maintain a pH > 14 at the immediate vicinity of uncorroded zinc for the desired service life. Anode units shall be supplied with integral well-separated tie wires without splices (in case of more than one wire) and with loop ties for directly tying to the reinforcing steel. For patches in a grid pattern or periphery of patches with 2-4 anodes/m2 area of concrete, the max spacing can be 600 mm. The anode size and shaping shall deliver a minimum current density to the steel adjacent to the repair of 0.4 mA/m2 of steel surface area at the end of the design life, taking into account an anode aging factor calculated from previous field installations and the in-service environment. Anodes should meet the target service life, which can be estimated using the Galvanic Anode Performance (GAP) test developed at IIT Madras for severe exposure conditions (high humidity and high chloride conditions). |
| 26 | The anodes shall be covered with bed-mortar of resistivity less than 50 kOhm-cm or similar to the parent concrete on the cleaned steel reinforcement as per the manufacturer's specification before applying passivation coating. All necessary design calculations for spacing of anodes, installation training, installation confirmation, monitoring of set of anodes to confirm current from anodes as per ISO 12696 or as per the design, etc. shall be carried out by a NACE Certified CP Technician, CP2 or higher, complete at all heights and including of all materials, labour, tools, plants and machineries as directed by Engineer-in-charge and/or consultant.
