[0002] Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete. It is widely used in civil engineering. Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates (also called aggregates), water, and admixtures and additives added when necessary in a certain proportion, which are then evenly mixed, compacted into shape, and cured and hardened.
