ROTOBASE®
Expanded Silicate Rock Powder
ROTOBASE® is the finest fraction of expanded silicate mineral powder offered by ROTEC®. The material is processed using a unique screening and treatment process developed in-house.
These fine silicates react with the calcium hydroxide liberated during the hydration of cement to produce caclium silicate hydrates. This leads to an improvement in the physical properties of all cement based construction products whilst offering a reduction in weight.
