Reinforcement of concrete slab front, by means of reinforced concrete overlay

Reinforcement of concrete slab front, 30 cm cant, by means of electric hammer chipping of deteriorated concrete, removing the deteriorated concrete until the reinforcement is exposed; cleaning of exposed reinforcement with dry particle projection of abrasive material (aluminum silicate), removing surface dirt, rust, and any substance that may reduce the adhesion between the reinforcement and the repair material to be applied, until a Sa 2 1/2 preparation degree is reached according to UNE-EN ISO 8501-1; manual application of one-component cement-based mortar, corrosion inhibitors, and powder polymers, for the protection and passivation of steel reinforcement, and as a bridge between the repair mortar and the existing concrete, ensuring adhesion between both, with a mean consumption of 1.5 kg/m2; overlay of the slab with reinforced concrete, made with HA-25/B/12/XC2 concrete manufactured in a central, and poured with a cubilote and UNE-EN 10080 B 500 S steel, with a quantity of 5 kg/m, with structural chemical anchoring, by means of 10 mm diameter and 85 mm depth perforation, filling the hole with epoxy resin injection, free of styrene, applied with a dosing nozzle and automatic mixing, and subsequent insertion of a galvanized steel screw with a 5.8 quality, according to UNE-EN ISO 898-1, 8 mm diameter and 110 mm length.
