Modified gangue-based coal mine filling cementing material
The invention discloses a modified gangue-based coal mine filling cementing material, and particularly relates to the field of material science and engineering, the modified gangue-based coal mine filling cementing material comprises the following raw materials by weight: 50 to 80 parts of modified gangue powder; 5 to 30 parts of fly ash; 10 to 30 parts of clinker; 3 to 20 parts of steel slag powder; and 2 to 30 parts of gypsum. The specific surface area of the modified gangue-based coal mine filling cementing material is 400-520 m < 2 >/kg, the modified gangue powder is powder formed by grinding gangue added with an alcohol amine grinding aid accounting for 1% of the mass of the gangue, and the specific surface area of the modified gangue powder is 400-500 m < 2 >/kg. The activity of the added modified gangue powder is stimulated through physical chemistry, a high-temperature modification link is reduced, energy conservation and environmental protection are achieved, 60%-90% of the raw materials belong to local traditional industry solid wastes, energy consumption and resource exploitation are not increased, local environmental protection pressure can be relieved, and the brick is green, environmentally friendly, low in cost, wide in raw material source and easy to obtain, the production process is simple, the energy consumption is low, and only grinding and mixing are needed.
本发明公开了一种改性矸石基煤矿充填胶凝材料，具体涉及材料科学与工程领域，包括包括以下重量份的原料：50～80份的改性矸石粉；5～30份的粉煤灰；10～30份的熟料；3～20钢渣粉；2～30份的石膏，所述改性矸石基煤矿充填胶凝材料的比表面积为400～520㎡/kg，所述改性矸石粉为通过矸石添加质量1%的醇胺类助磨剂粉磨而成的粉体，改性矸石粉的比表面积为400～500㎡/kg。本发明添加的改性矸石粉通过物理化学激发其活性，减少了高温改性的环节，节能环保，原材料60%～90%均属于当地传统行业固体废弃物，不增加能耗和资源开采且能缓解当地的环保压力，绿色环保一举多得，成本低，原材料来源广泛易得，生产工艺简单，耗能小，只需要粉磨混合即可。
