Rofluid H1 is a raw material used in concrete admixtures. It is an aqueous solution of polycarboxylate ether. It improves the workability of concrete by reducing the amount of water needed. It also increases the compressive strength of concrete and can be used at lower temperatures. Rofluid H1 does not cause corrosion of reinforcing steel and is suitable for various concrete applications such as precast, waterproof, architectural, and self-compacting concrete.
