Silica Sand - an overview | ScienceDirect Topics
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 | Its Properties and 7 Uses of Silica Sand
Sources of Silica Sand: SiO2 is the chemical sign of silica and it is actually the group of minerals which is a mixture of Oxygen and Silicon. This sand is often got in the crystalline state and because of weathering, plankton fossilization takes place and that results in crystallizing SiO2. In most regions of the world, these are found as mines and it is obtained in high hardness.

What is Silica? | Eurosil
The silica in the sand will normally be in the crystalline form of quartz. For industrial use, pure deposits of silica capable of yielding products of at least 95% SiO2 are required. Often much higher purity values are needed. Silica sand may be produced from sandstones, quartzite and loosely cemented or unconsolidated sand deposits.
