Sodium Silicate - an overview ScienceDirect Topics

S.A. Jefferis, in Advanced Concrete Technology, 2003 12.15.5.1 Silicate–ester grouts. Sodium silicate is effectively a solution of silica in sodium hydroxide. If the sodium hydroxide is neutralized with an acidic material the silica will precipitate. The form of the precipitated silica is influenced by the nature of the neutralizing material.

Silica Sand - an overview ScienceDirect Topics

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.

Silica Statistics and Information - USGS

2 天前  Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are
