    MasterRheobuild 840 - A high range, water-reducing superplasticiser for rheoplastic concretes 


    MasterRheobuild 840 is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete. A rheoplastic concrete is a fluid concrete, easily flowing; but at the same time free from segregation and bleeding having the same w/c ratio as that of a low slump concrete without admixture, with a slight set retarding effect for producing free-flowing concrete in hot climates. Also, it provides a substantial water reduction effect for promoting high, early and ultimate strengths. MasterRheobuild 840 is chloride-free.
