Fly ash is the main solid waste discharged from coal-fired power plants. Specifically, when lignite and sub bituminous coal are used as fuel in power plants, a kind of fly ash with high calcium oxide content is discharged, which has the characteristics of high compressive strength and small fineness screening residue. Therefore, it can be widely used in the production of various building materials, including cement, concrete, wall materials, filling materials and road base materials.
How to make full use of fly ash has become an important topic of environmental protection. SMMVIK Machinery, the leader of the mining machinery industry, has made many attempts. The following uses were found:
1. The expansion agent is prepared by mixing and grinding fly ash, fluorogypsum and steel slag powder treated by special water quenching process in a certain proportion. This expansion agent has the advantages of non alkali, high activity and low cost, and can resist the shrinkage of cement in the later hydration period.
2. As a mixing material of slag cement, it can reduce the bleeding of slag cement, improve the mill yield, and reduce the loss of abrasive and liner.
