Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid. It is the second-most-used substance (after water), the most widely used building material, and the most-manufactured material in the world. Cement-bound concrete differs from the less rigid, less durable asphaltic concrete, which has a…
