To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime 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.

Silica sand is a product of mechanical and chemical weathering of quartz-bearing igneous and metamorphic rocks such as granites and chemical weathering breaking down the less stable minerals such as feldspars and releases the more stable ones such as quartz and zircon. The stable mineral fragments are transported and re-deposited in water.
