AI overview

Cement is a powder material that is mixed with aggregates (like sand and gravel) and water to create concrete, a durable building material used in construction. It matters because concrete made from cement is one of the most widely used materials in the built environment, as evidenced by its long history of application in structures like cement blocks.

A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.
