Concrete is a combination of paste and aggregates, or rocks, in its simplistic definition. The paste, consisting of portland cement and water, is placed on the fine (small) and coarse (bigger) aggregates. The paste thickens and accumulates solidity as a product of a chemical process called hydration, leading to the formation of the rock-like reference to the fact as concrete.

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.
