    Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material in ARC-32. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined
