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 aggregat Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete...
