Is silica sand used for concrete?

Yes, silica sand is commonly used in concrete as an aggregate to create high-strength and durable concrete mixes. Silica sand serves as an important ingredient in the production of concrete, as it helps to reduce the amount of water required, improve the strength of the cement, and increase the volume and density of the finished product.
