商品混凝土（commercial concrete） The so-called commodity concrete refers to the production in the factory, and sold as a commodity concrete. Compared with field mixing concrete, the provision of concrete to the construction site in the form of commercial concrete has the following advantages. The commercial concrete mixing plant is a professional concrete production enterprise, equipped with advanced equipment, the equipment has high yield, and the measurement is accurate, stirring evenly, produce better quality of concrete. Production personnel have been engaged in the production of commercial concrete, and have extensive experience in this field. Commercial concrete enterprises generally have a sound quality assurance system. Concrete is the ultimate product of these enterprises, and enterprises must be responsible for the quality of these products.
