In concrete, sand and stone act as a framework, called aggregate; the cement and water form cement paste, and the cement paste wraps the surface of the aggregate and fills gaps of the aggregate. Before hardening, the cement slurry plays a role in lubrication, so that the mixture is endowed with certain workability, and the construction is convenient. After the cement slurry is hardened, the aggregate is cemented into a solid whole.
