cement chemical reaction

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 …

The chemical reaction between alkalis in cement and reactive silica constituents present in aggregate is known as ASR, which produces a gel reaction product that swells when it imbibes water. The expansion of the gel is deleterious, as it increases the internal pressure in concrete, subsequently resulting in cracking of the concrete and finally the loss of integrity of structure
