MasterRheobuild 870 - A high range, water-reducing superplasticiser for rheoplastic concretes

Formerly Rheobuild 870

Description

MasterRheobuild 870 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 870 is chloride-free.

Where is MasterRheobuild 870 applied?

  • Microsilica concrete
