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.

The silica sand type abrasive media when used in abrasive blasting, typically fractures into fine particles and becomes airborne. When workers inhale the crystalline silica, the lung tissue reacts by developing fibrotic nodules and scarring around the trapped silica particles [Silicosis and Silicate Disease Committee 1988].

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.

What is Silica Sand? Silica Sand is also known as Quartz Sand as it is the derived product of Quartz. With the friction of water and wind, quartz broke down into tiny granular molecules. Thus, Silica Sand is formed. They are fine non-crystalline molecules of SiO2. The mineral composition of Silica (SiO2) is a mixture of Silicon and Oxygen.
