Silica sand is a key ingredient in the production of cement. It is used as a raw material in the manufacturing process. Silica sand is added to the cement mixture during the grinding process to control the setting time of the cement and improve its overall strength.

In addition to its physical properties, silica sand is also valued for its chemical properties. It reacts with calcium oxide to form calcium silicate, a key component of cement. This reaction is what gives cement its strength and durability.
