Anti-cracking and anti-corrosion concrete and preparation method thereof
The invention discloses anti-cracking and anti-corrosion concrete and a preparation method thereof. The anti-cracking and anti-corrosion concrete comprises the following components in parts by weight: 190-200 parts of water, 230-260 parts of Portland cement, 50-65 parts of fly ash, 55-65 parts of mineral powder, 720-830 parts of medium sand, 1000-1130 parts of stone, 6-10 parts of modified polypropylene fibers, 1-1.5 parts of an air-entraining type waterproof agent, 1-1.5 parts of a micro-expansion type waterproof agent, 10-15 parts of diatom ooze, 1.5-2 parts of a sodium sulfite water reducing agent, and 0.75 kg/m of a water absorbing material. The concrete has the beneficial effects that 20%-40% of the starch grafted acrylate water absorbing material is added in the concrete preparation process, and water is supplemented into the concrete through the water absorbing material, so that the relative humidity in the concrete is always kept at a relatively high level, the early cracking of the concrete caused by insufficient maintenance can be effectively relieved, and the problem of maintenance difficulty caused by special climate conditions in different regions can be solved.
本发明公开了一种防裂防腐混凝土及其制备方法，包括如下重量份数的组分：水：190‑200份；硅酸盐水泥：230‑260份；粉煤灰：50‑65份；矿粉：55‑65份；中砂：720‑830份；石子：1000‑1130份；改性聚丙烯纤维：6‑10份；引气型防水剂：1‑1.5份；微膨胀型防水剂：1‑1.5份；硅藻泥：10～15份；亚硫酸钠减水剂：1.5‑2份；吸水材料：0.75kg/m³。本发明所达到的有益效果是：混凝土制备过程中加入20%‑40%的淀粉接枝丙烯酸盐类吸水材料，通过吸水材料在混凝土内部补充水分，使混凝土内部相对湿度始终保持较高水平，既可有效缓解因养护不足导致的混凝土早期开裂，又能克服不同地区特殊气候条件造成的养护困难问题。
