Cement making process

Explore the cement manufacturing process below. Cement Vs. Concrete . Cement is often confused with concrete. A common misconception is cement and concrete are interchangeable terms. In reality, cement is the glue that binds concrete together, like flour (cement) in a loaf of bread (concrete)

  • How Concrete is Made - Portland Cement Association

    How Concrete is Made - Portland Cement Association

    How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete
