[0002] Concrete, abbreviated as "砼", is a general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which uses cement as the cementitious material, sand and stone as the aggregate, and is mixed with water (which may contain admixtures and additives) in a certain proportion and stirred.
