Types of Concrete

Concrete is the fundamental material used in civil engineering such as building materials for building structures. Concrete is an aggregate mixture of cement, sand, and fine and coarse rock pieces. The cement acts as a binding material that holds the compositions together, sets, and hardens with time. Apart from cement, there are other different types of binding materials used, such as lime concrete, bitumen, asphalt, and so on.
