Product Description

Classic Crete RMW (Powder) is a light yellow powder based on a selected napthalene sulphonated condensates. Concrete however well made is to some extent porous and water must be prevented from penetrating through capillary pores. The presence of water must in hardened concrete can cause corrosion of reinforcement which is made by freezing and thawing of concrete containing absorbed moisture. Further deterioration can occur if the water penetrating the concrete contains dissolved aggressive salts. Classic Crete RMW (Powder) provides protection against deterioration due to the pores, left by the slow evaporation of the excess water not taken up by hydration of cement. Classic Crete RMW (Powder) entrains a controlled amount of air which does not increase with the dosage. The risk of capillary suction is reduced by the induced air which blocks the pores. The plasticizing action of Classic Crete RMW (Powder) aids in producting denser concrete/ mortar with greatly reduced permeability.
