At present, most of the domestic mines are mainly paste filling mining, in the process of paste filling, gel material is essential, the traditional gel material to ordinary Portland cement, this kind of gel material cost is higher. Many mines, in order to reduce the cost of filling materials, there have been some cement substitutes, including blast furnace slag, fly ash, etc., these materials after activation, part or all of the cement formed by the agent.
However, with the continuous advancement of filling mining, our research on cement substitutes has been uninterrupted. In addition to blast furnace slag and fly ash instead of cement, domestic experts have also carried out other explorations and achieved certain results. Some studies claim that slag, lime, loess, etc. are used as the main materials and modifiers are added to have the performance of gelling. The use of slag, fly ash and other alternative cement as filling cementitious materials, not only can greatly reduce the cost of filling, but also can reduce the consumption of energy in the process of cement production, therefore, the new type of cementitious materials, has a very broad application prospects.
