Impermeable concrete and preparation method thereof
The invention discloses impermeable concrete, which is prepared from the following raw materials in parts by weight: 200 to 240 parts of cement, 45 to 60 parts of fly ash, 55 to 75 parts of mineral powder, 1130 to 1390 parts of coarse aggregate, 35 to 45 parts of silica fume, 600 to 660 parts of river sand, 60 to 75 parts of rubber particles, 12 to 16 parts of polypropylene fiber, 6 to 10 parts of water reducing agents, 3 to 8 parts of waterproof agents and 145 to 180 parts of water. According to the impervious concrete and the preparation method thereof, by adding the fly ash, the mineral powder, the coarse aggregate, the silica fume, the rubber particles and the polypropylene fibers, the tensile strength, the compressive strength and the flexibility of the concrete can be enhanced, meanwhile, the cohesiveness of the concrete can be improved, and the layering phenomenon of the concrete is improved, so that the concrete is not prone to cracking, and the service life of the concrete is prolonged. And secondly, a fiber net-shaped structure is formed in the concrete, so that the concrete has the effect of higher tensile strength.
本发明公开了一种抗渗混凝土，包括以下重量份数配比的原料：水泥200～240份、粉煤灰45～60份、矿粉55～75份、粗骨料1130～1390份、硅灰35～45份，河砂600～660份、橡胶颗粒60～75份、聚丙烯纤维12～16份、减水剂6～10份、防水剂3～8份和水145～180份。该抗渗混凝土及其制备方法，通过添加粉煤灰、矿粉、粗骨料、硅灰、橡胶颗粒和聚丙烯纤维，有利于增强混凝土的抗拉伸强度、抗压强度和柔韧性，同时还可提升混凝土的粘聚性，改善混凝土的分层现象，从而使得混凝土不易产生开裂，改善抗渗混凝土产生裂缝的情况，其次，在混凝土内形成纤维网状结构，使混凝土获得了较高抗拉伸强度的效果。
