LOW-CARBON CEMENTITIOUS MATERIAL OF SILICON-MANGANESE SLAG FOR FILLING, PREPARATION METHOD AND APPLICATION THEREOF

The invention discloses a low-carbon cementitious material of silicon-manganese slag for filling, a preparation method and application thereof, belonging to that technical field of underground filling of metal and nonmetal mines, and comprises the following raw materials in parts by mass: 40-80 parts of silicon-manganese slag micropowder, 20-40 parts of blast furnace slag micropowder, 5-15 parts of carbide slag, 10-20 parts of by-product gypsum and 0.2-1 part of admixture. According to the invention, various industrial solid wastes mainly made of silicon-manganese slag are used as raw materials, and cement clinker is not needed to be added, so that the low-carbon cementitious material made of silicon-manganese slag for filling is prepared, the secondary utilization of industrial solid wastes is realized, the CO2 emission is reduced, and the method is low-carbon and environment-friendly, and the problem of high cost caused by using superfine tailings and ordinary cement as cementing agents to prepare filling materials is solved.
