Rofluid S is a milky to transparent aqueous solution of polycarboxylate ether (PCE) that acts as a plasticizer in concrete. It improves the hydration process of cement and maintains stable consistency over time. Rofluid S reduces the amount of water needed and increases compressive strength while minimizing costs. It is compatible with other products in the Rofluid series and can be used for ready-mixed concrete, massive elements, and specialized concrete.
