TARGET® Traffic PATCH™ Coarse (9991178) consists of specially modified Portland cement and aggregates combined in closely controlled proportions to give a rapid setting material for the repair of concrete. The product meets the requirements of ASTM C928 for very rapid hardening concrete repair materials. The rapid strength gain properties are maintained at temperatures as low as 3 °C (37 °F). The product contains no calcium chloride or other admixtures likely to accelerate the corrosion of reinforcing steel. It is available in Fine and Coarse aggregate gradations. The TARGET® Traffic PATCH™ Fine incorporates polypropylene fibres and is intended for use in patches up to 25 mm (1 inch) thick. The TARGET® Traffic PATCH™ Coarse incorporates 30 mm long steel fibres and is designed for use in patches with thicknesses of more than 25 mm (1 inch).
It is designed for use as a repair material for cast-in-place or precast concrete where rapid setting and strength gain of the repair are required. Typical applications include patching of bridge decks, roads, curbs, sidewalks, parking decks and warehouse floors where the repaired area must be returned to normal service conditions within two hours of placing the repair mix.
When mixed as directed, each 25 kg (55 lb) bag will yield approximately 0.43 ft³ (12.1 L) of repair material.
