  • How Concrete is MadeCement

    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.

Before we add aggregates to the concrete mix we clean them to remove any dust dirt or other organic impurities. We also sort aggregates by size. Using aggregates of roughly the same size helps ensure that the concrete is stable.
