Polypropylene modified concrete and preparation method thereof
The invention relates to polypropylene modified concrete and a preparation method thereof, and belongs to the field of concrete coatings. The concrete is prepared from the following raw materials in parts by weight: 15-25 parts of polypropylene fiber, 430-440 parts of cement , 1500-1600 parts of mixed aggregate, 8.5-9.0 parts of a water reducing agent, 45-60 parts of diatomite, 0.5-0.6 part of a retarder and 150-170 parts of water. Fine aggregate is replaced by polypropylene plastic particles, and then the polypropylene fiber is added, so that the permeation resistance and the bending ductility of the concrete are improved while the mechanical property of the concrete is guaranteed, the whole preparation method is simple, and the concrete suitable for large-scale industrial production.
本发明涉及一种聚丙烯改性的混凝土及其制备方法，属于混凝土涂料领域。本发明混凝土原料包括如下重量份数：聚丙烯纤维15‑25份、水泥430‑440份、混合骨料1500‑1600份，减水剂8.5‑9.0份、硅藻土45‑60份，缓凝剂0.5‑0.6份，水150‑170份。本发明通过聚丙烯塑料颗粒取代细骨料，再加入聚丙烯纤维，在保证混凝土的力学性能的同时，还改善了混凝土抗渗透和弯曲延性，本发明整体制备方法简单，适用于大规模的工业生产。
