The invention provides polypropylene fiber concrete and a preparation method thereof, and belongs to the technical field of concrete, the polypropylene fiber concrete is prepared by uniformly mixing 320-330 parts by weight of recycled aggregate, 610-620 parts by weight of fine aggregate, 380-390 parts by weight of cement, 1.2-1.5 parts by weight of polypropylene fiber, 1.5-2.0 parts by weight of glass powder, 0.8-1.0 part by weight of nano silicon dioxide, 5-7 parts by weight of a water reducing agent and 170-180 parts by weight of water. Through the synergistic effect of the nano silicon dioxide, the glass powder and the polypropylene fiber, the problems that the mechanical property and the freeze-thaw resistance become poor due to the fact that the recycled aggregate is used for preparing the concrete are effectively solved, recycling of the recycled aggregate is well achieved, and the compression resistance and the freeze-thaw resistance of the prepared polypropylene fiber concrete are improved.
本发明提供一种聚丙烯纤维混凝土及其制备方法，属于混凝土技术领域，所述聚丙烯纤维混凝土是取再生骨料320～330重量份、细骨料610～620重量份、水泥380～390重量份、聚丙烯纤维1.2～1.5重量份、玻璃粉1.5～2.0重量份、纳米二氧化硅0.8～1.0重量份、减水剂5～7重量份和水170～180重量份混匀制得。本发明通过纳米二氧化硅、玻璃粉和聚丙烯纤维的协同作用，有效解决了使用再生骨料制备混凝土导致的力学性能及抗冻融性能变差等问题，很好的实现了再生骨料的循环利用，提高了所制聚丙烯纤维混凝土的抗压性能和抗冻融性能。
