Concrete is the second-most used material in the world, second only to water. It’s made of a blend of aggregates (typically normal sand and gravel or crushed rock) bound together by a hydraulic binder. The ultimate result is a material that is very strong and resistant to compression – it has also been referred to as an artificial rock.
