Background

The common concrete is artificial stone which is prepared by taking cement as a main cementing material, adding water, sand, stones and chemical additives and mineral admixtures if necessary, mixing the materials according to a proper proportion, uniformly stirring, densely molding, curing and hardening. Concrete is mainly divided into two stages and states: plastic state before setting and hardening, namely fresh concrete or concrete mixture; hardened, i.e. hardened concrete or concrete. 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.

In concrete production, in order to seek better mixing effect, cement and sand are generally added and mixed with water to form a slurry mixture, and then stones are added to be used as a framework for shaping, so that the problem that the cement or the sand is adhered to the surface of the stone at the beginning, and the quality of the concrete is affected due to insufficient overall stirring can be avoided.
