    How Concrete is Made Portland Cement Association

    How Concrete is Made. In its simplest form,concreteis a mixture of paste and aggregates, or rocks. The paste, composed of portlandcementand 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 asconcrete. Within this process lies the key to a remarkable trait of …
