MasterRheobuild 865 - A high range, water-reducing superplasticiser for rheoplastic concretes
Formerly Rheobuild 865
MasterRheobuild 865 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. Also, it provides a substantial water reduction effect for promoting high, early and ultimate strengths.
MasterRheobuild 865 is chloride-free.
