Rock Concrete Hardener an Awarded first price by India Chapter of American Concrete Institute(USA) in 2004. RCH is specially designed to produce High Performance Concrete. Addition of 5-10% RCH compared to cement in the concrete mix leads to increase in compressive strength by more than 50% & flexural strength increase by more than 100% at different ages. RCH dispersed well in concrete through the mess of concrete to make the mix more cohesive & less prone to segregation. Advantages of using RCH in concrete mix lower heat of hydration, Improving its durability & impermeability, lower drying & plastic shrinkage. Reduces cracks, good impact resistance & highly abrasive resistance to increases the concrete life. RCH can use for designing the concrete mix proportions various grades from M-20 to M-75. RCH use in High Performance Concrete such as airport & highway pavements in bridge deck over lays, sewage pipe, cavitations or erosion resistance structures, like spillways, sewage way, bridge piers, pre-cast concrete products, earthquake resistance structures as missile silo & ready mix concrete plants.
