Concrete

Concrete is a construction material composed of cement as well as other cementitious materials such as fly ash and slag cement, aggregate water, and chemical admixtures. Concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a stone-like material. Concrete is used to make pavements, pipe, architectural structures, foundations, motorways/ roads, bridges/ overpasses , parking structures, brick / block walls and footings for gates, fences and poles. .
