MasterRheobuild 890 - A high range, water-reducing superplasticiser for rheoplastic concretes

Formerly Rheobuild 890


MasterRheobuild 890 is formulated from synthetic polymers specially designed to impart rheoplastic qualities to concrete. 

A rheoplastic concrete is a fluid concrete with a slump of at least 200mm, easily flowing, but at the same time free from segregation and having the same w/c ratio as that of a low slump concrete (25mm) without admixture. 

MasterRheobuild 890 is chloride-free
