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 170 C 340 F 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.
The sand that fills in around the facing sand is called backing sand. This sand is simply silica sand with only a small amount of binder and no special additives. Types of base sands.
