Conplast SP490-S is a high-range water-reducing admixture designed for use in high-quality concrete where workability retention and low water content are crucial. It is particularly suitable for piling, mass concrete pours, and applications requiring good pumpability and improved cohesion. The admixture is based on selected synthetic and organic polymers, dispersing fine particles in the concrete mix to enhance the effectiveness of the water content. This allows for significant increases in strength and improved durability. It is chloride-free and safe for use in reinforced and prestressed concrete.
