Conplast SP430 ES2 is a chloride free, superplasticising admixture based on selected sulphonated napthalene polymers. It is supplied as a brown solution which instantly disperses in water. Conplast SP430 ES2 disperses the fi ne particles in the concrete mix, enabling the water content of the concrete to perform more eff ectively. The very high levels of water reduction possible allow major increases in strength to be obtained.
Makes possible major reductions in water cement ratio which allows the production of high strength concrete without excessive cement contents. Increased workability levels are maintained for longer than with ordinary sulphonated melamine and napthalene admixtures Improved cohesion and particle dispersion minimises segregation and bleeding and improves pumpability. Chloride free, safe for use in prestressed and reinforced concrete
