With the development of society, China is facing unprecedented pressures on power resources and the environment; on the other hand, the improvement of skills has also created conditions for China to ease the pressure on resources, power and the environment. The comprehensive use of abandoned resources in the occupation of cement and cement products has received great attention from the whole society, and has been greatly developed in recent years. The skills of discarding resources in the career of cement and cement products are becoming more sophisticated and the skill level is getting higher and higher. Discarding resources is becoming one of the important raw materials for the professional production of cement and cement products in China. Comprehensive use of solid wastes Solid wastes can be divided into industrial solid wastes and municipal waste.

For the cement and cement products profession in China, the comprehensive use of industrial solid waste is mainly reflected in the mixing of fly ash and slag as a mixed material in the preparation of cement and cement products , and it is rare to use them as substitute materials .

A total of 210 million tons of industrial solid waste such as fly ash, slag, tailings, and coal gangue were used in the cement occupation, accounting for 41.76% of the total occupational use. As for the comprehensive use of urban waste, our country is still in the experimental stage, and most of them have not formed sophisticated craftsmanship. In the past few years, some manufacturers have conducted trial firing experiments of sludge, tires and waste, and the results show that it is necessary and feasible to use combustible waste to calcinate clinker in China.
