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.

These ‘impurities’ make regular sand more chemically reactive and often darker in colour when compared to silica sand. The color for non-silica sands (regular sands) can be various shades white, pink, green, and black as well – depending on the geological makeup and geographic location of the sand deposit.

2020-5-20 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.
