R3

Purpose: 

R3 is a high performance, rapid setting, rapid hardening, high-early strength concrete patching material designed for horizontal, vertical and overhead applications. R3 is a blend of carefully selected portland cements, selected aggregates and proprietary admixtures. R3 provides outstanding resistance to the damaging effects of freeze/thaw cycles and deicing solutions. R3 is easy to use, non-sag and creamy in texture. Additionally R3 can be shaped-to-form once sufficient set is achieved.
