Before China Cement, most of the cement was mainly bagged cement, and the production process of bagged cement was complicated, which consumed a lot of manpower and material resources. The proportion of bulk cement in developed countries such as Europe has reached more than 90%. In order to vigorously develop bulk cement and promote the process of bulk cement in China, at the end of the 20th century, the building materials industry vigorously carried out the work of pushing and dispersing, and set up a special fund for bulk cement.
