Silica, also known as quartz or cristobalite, is made up of fine particles much smaller than a grain of sand. Respirable silica refers to particles with a diameter less than 10 μm; these smaller particles are less likely to be trapped in the nose and throat and are more likely to reach the lungs. How Are Individuals Exposed to Silica? According to OSHA, "exposures occur when workers cut ...

Get PriceTo 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.
