Impermeable layer material and application thereof
The invention relates to an impermeable layer material and application thereof, every 100 parts by weight of the impermeable layer material comprises 50-85 parts by weight of tailings, 1-10 parts by weight of tailings pond subsoil, 2-10 parts by weight of cement, 1-10 parts by weight of blast furnace slag, 1-10 parts by weight of bentonite, 0.3-5 parts by weight of gypsum, 0.3-5 parts by weight of lime and 0-0.2 part by weight of a polycarboxylate superplasticizer. During use, 13-30 parts of water is added into every 100 parts of the impermeable layer material. The impermeable layer material is low in manufacturing cost and easy to construct, the prepared impermeable layer is large in elasticity modulus, and the plasticity can effectively cope with large deformation; the permeability coefficient is low, the problem of pollutant leakage in a solid waste storage and disposal site can be solved, and it is ensured that leachate of solid waste cannot permeate underground.
本发明涉及一种防渗层材料及其应用，按重量份计，每100份防渗层材料包括：50～85份尾矿，1～10份尾矿库底土，2～10份水泥，1～10份高炉矿渣，1～10份膨润土，0.3～5份石膏，0.3～5份石灰，0～0.2份的聚羧酸减水剂；使用时，每100份防渗层材料添加13～30份水。该防渗层材料造价便宜、易于施工，制备的防渗层弹性模量大，塑性能有效应对大形变；渗透系数低，可解决固体废弃物贮存处置场所的污染物渗漏问题，确保固体废物的浸出液不会渗透到地下。
