MasterRheobuild 857K - High range water reducing superplasticiser
What is MasterRheobuild 857K?
MasterRheobuild 857K 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 200 mm, easily flowing, but at the same time free from segregation and having the same water/cement ratio as that of a low slump concrete (25mm) without admixture. MasterRheobuild 857K is chloride free.
What is MasterRheobuild 857K used for?
MasterRheobuild 857K considerably improves the properties of fresh and hardened concrete.
