The invention discloses impermeable wear-resistant concrete and a preparation method thereof, and relates to the technical field of concrete preparation. The impermeable wear-resistant concrete comprises the following raw materials: cement, fly ash, blast furnace slag, quartz sand, broken stone, carbon black, a fiber filler, sodium alkyl benzene sulfonate, a water reducer, polyvinyl alcohol, an impermeable wear-resistant composition and water. The preparation device comprises a batching mechanism, a lifting and conveying mechanism and a mixing and stirring mechanism, wherein the discharging port end of the batching mechanism is connected with the feeding end of the lifting and conveying mechanism; and the discharging end of the lifting and conveying mechanism is connected with the discharging end of the mixing and stirring mechanism. According to the impermeable wear-resistant concrete and the preparation method thereof provided by the invention, prepared materials can be transferred at the same time, so that automatic unloading after weighing is realized; the inner wall of a lifting pipeline can be effectively prevented from being blocked while the materials are lifted and conveyed upwards; and the preparation method is simple, and the prepared concrete has the characteristics that the water-reducing rate is high, the workability and the fluidity of the road concrete are obviously improved, and the impermeability, the freezing resistance, the fracture resistance, the compression resistance, the wear resistance and the durability of the road concrete are improved.
本发明公开了一种抗渗耐磨混凝土及其制备方法，涉及混凝土制备技术领域，包括以下原料：水泥、粉煤灰、高炉矿渣、石英砂、碎石、碳黑、纤维填料、烷基苯磺酸钠、减水、聚乙烯醇、抗渗耐磨组合物和水；制备装置包括配料机构、提升输送机构和混合搅拌机构，配料机构的出料口端与提升输送机构的进料端相连接，提升输送机构的出料端与混合搅拌机构的出料端相连接；本发明可同时对配制好的物料进行转移，实现了称重后的自动化卸料；在对物料向上进行提升输送的同时能有效避免提升管道内壁的堵塞；制备方法简单，所制成的混凝土有减水率高、明显改善道路混凝土和易性、流动性，提高道路混凝土抗渗、抗冻、抗折、抗压及耐磨耐久性等特点。
