In construction and engineering, cement is a binder, a substance used for building that sets, hardens, and adheres to other materials to bind them together.

Cement is produced by heating a mixture of limestone and clay to high temperatures in a kiln, creating clinker. This clinker is then ground into a fine powder, often with the addition of gypsum. When mixed with water, cement undergoes a chemical reaction called hydration, which causes it to harden and gain strength.
The properties of cement can be modified by adding other materials, such as fly ash, slag, or
