The invention discloses a wear-resistant impervious cement-based material as well as a preparation method and application thereof, and belongs to the technical field of cementing materials. The wear-resistant impervious cement-based material provided by the invention is prepared from the following preparation raw materials in parts by mass: 400-800 parts of a cementing material, 200-400 parts of water, 15-150 parts of a wear-resistant auxiliary agent, 0-30 parts of a water reducing agent and 0-20 parts of a surface modifier, the wear-resistant additive is selected from ultra-high molecular weight polyethylene powder. The wear-resistant additive ultra-high molecular weight polyethylene has excellent wear resistance and extremely low water absorption rate, the permeability of the cement-based material can be greatly reduced when the wear-resistant additive ultra-high molecular weight polyethylene is used for modifying the cementing material, and the obtained cement-based material has lower water absorption rate and capillary absorption coefficient, has a compact pore structure and better hydrophobic property, and can be used for preparing the cement-based material. The anti-permeability and durability are excellent, the service life of the cement-based material can be effectively prolonged, and the later maintenance and maintenance cost of a large capital construction project is reduced.
本发明公开了一种耐磨抗渗水泥基材料及其制备方法和应用，属于胶凝材料技术领域。本发明提供的耐磨抗渗水泥基材料由包括以下质量份数的制备原料制得：400～800份胶凝材料、200～400份水、15～150份耐磨助剂、0～30份减水剂、0～20份表面改性剂；所述耐磨助剂选自超高分子量聚乙烯粉料。本发明的耐磨助剂超高分子量聚乙烯具有优异的耐磨性能与极低的吸水率，利用其对胶凝材料进行改性，可大幅降低水泥基材料的渗透率，得到的水泥基材料具有较低的吸水率和毛细吸收系数，具有致密的孔结构及较好的疏水性能，抗渗性能和耐久性能优异，可有效提升水泥基材料的使用寿命，降低大型基建工程后期的维修与养护成本。
