Calcium Silicate Blocks

We are involved in offering Calcium Silicate Blocks. The raw materials for calcium silicate bricks include lime mixed with quartz, crushed flint or crushed siliceous rock together with mineral colorants. The materials are mixed and left until the lime is completely hydrated, the mixture is then pressed into molds and cured in an autoclave for two or three hours to speed the chemical hardening.
