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 precipitation. Two hundred mL of geothermal brine with a monomeric silica concentration of 6.96 × 10 −3 mol/L was collected from the Dieng plant Unit 3A–3B, and hydrochloric acid was added to lower the pH to 2.5 to prevent precipitation of the silica. The brine was then poured into a 250-mL beaker glass, placed on a hot magnetic stirrer plate, and up to …
