Composite Materials - Concrete - DESIGN AND TECHNOLOGY

Concrete is regarded as a composite material because it is composed of a number of materials that combine to form this versatile building material. Most concrete is made up of Portland Cement, aggregates (gravel, crushed Water is added to the mix. Concrete can be purchased as precast products, such as paving stones.
