Concrete Basics - ConcreteState

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.

Portland Cement - Lehigh Hanson, Inc

Cement is an ingredient of concrete. It’s the fine grey powder that, when mixed with water, sand and gravel or crushed stone, forms the rock-like mass known as concrete. Cement typically accounts for 10% to 12% of the concrete mixture. Cement acts as the binding agent or glue in concrete. When combined with water, cement forms a paste that
