Molybdenum tailing sand polymer cement waterproof mortar and preparation method thereof
The invention relates to molybdenum tailing sand polymer cement waterproof mortar and a preparation method thereof, and belongs to the technical field of novel building materials, the molybdenum tailing sand polymer cement waterproof mortar comprises the following components by mass: 40%-45% of cement, 50%-55% of molybdenum tailing sand, 2%-3% of silica fume, 2.2%-3% of redispersible latex powder, 0.1%-0.2% of cellulose ether, and 0.4%-0.7% of an additive. The average value of physical properties of the polymer cement waterproof mortar is as follows: 28-day compressive strength is greater than or equal to 28 MPa, 28-day breaking strength is greater than or equal to 8 MPa, 28-day tensile adhesive strength is greater than or equal to 1.2 MPa, and 28-day impermeable pressure is greater than or equal to 1.5 MPa. The molybdenum tailing sand is used for replacing natural sand to serve as aggregate in the polymer cement waterproof mortar, and tailing solid waste is reasonably utilized, so that the utilization rate of the molybdenum tailing sand is greatly increased; the cost of building materials is saved, meanwhile, the use of non-renewable resource natural sand is reduced, and the ecological environment is better protected.
一种钼尾矿砂聚合物水泥防水砂浆及其制备方法，属于新型建筑材料技术领域，其组分按质量百分比包括：水泥40％～45％，钼尾矿砂50％～55％，硅灰2％～3％，可再分散性乳胶粉2.2％～3％，纤维素醚0.1％～0.2％，外加剂0.4％～0.7％。其物理性能平均值为：28天抗压强度≥28MPa，28天抗折强度≥8MPa，28天拉伸粘结强度≥1.2MPa，28天抗渗压力≥1.5MPa本发明通过利用钼尾矿砂代替天然砂作为聚合物水泥防水砂浆中的骨料，将尾矿固废合理化利用，极大的提高了钼尾矿砂的利用率，节约了建筑材料的成本，同时减少了不可再生资源天然砂的使用，对生态环境进行更好保护。
