Silica Sand - an overview ScienceDirect Topics

2012-9-4  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.

1. Introduction Silica sand is one of the most abundant minerals that can be found in diverse ways such as in quartz crystals, huge forming hills, quartz sand or silica sand, sand stone and so forth. It is quartz that over time, through the work of water and wind, has been broken down into tiny granules.
