Silica Sand An Overview Sciencedirect

To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sandlime ratio of 10 or 20. The mix is then compressed into moulds and autoclaved at about 170C (340F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.
