How Do I Process Silica Sand

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.Sep 04, 2012 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.
