  • 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. Within this process lies the key to a remarkable trait of concrete its

    Sep 23, 2020 The installation process of exposed aggregate concrete is pretty much the same as regular concrete. However, nylon-bristled brushes and water is used after the surface has cured partially to remove a part of the cement. This helps the surface achieve a slightly stubby texture thereby giving it more traction even in wet and humid condition.
