Pingdingshan City is a city with a large amount of discharged fly ash. The utilization of fly ash can not only improve the environment and benefit people, but also save material, reduce energy consumption, and increase economic efficiency. Practice has proved that replacing some of the cement in concrete with fly ash can be applied to small-scale prefabricated hollow slab plants. The application and related technologies are now described as follows: 1 Raw material conditions and performance Cement: Pingdingshan Cement Factory
