    The Constituent Materials of Ordinary Concrete : u/Bunch19

    Ordinary concrete (referred to as concrete for short) is composed of cement, sand, stone, and water. In order to improve certain properties of concrete, appropriate additives and admixtures are often added. In concrete, sand and stone act as a skeleton and are called aggregates; cement and water form cement slurry, which wraps the surface of the aggregate and fills its voids. Before hardening
