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 Pool Filter. Silica sand works great in a variety of pool filters, given that it is often cost effective, eco-friendly, and easy to use. Having silica sand around can make your pool or backyard pond cleaner than it was- it has the capabilities of filtering out both large and fine microns. 9. Sandblasting.

Yes, silica sand is commonly used in concrete as an aggregate to create high-strength and durable concrete mixes.
