Anti-crack concrete and proportion optimization method thereof
The invention discloses anti-crack concrete and a proportioning optimization method thereof in the field of building materials, and the anti-crack concrete is prepared from the following raw materials in kg/m < 3 >: 132 kg of water, 330 kg of cement, 2.64 kg of an additive, 755.44 kg of gravel, 493.02 kg of fine aggregate, 739.54 kg of coarse aggregate, 0-33 kg of magnesium oxide and 0-1.2 kg of polypropylene fiber. According to the scheme, the cement, the aggregate, the gravel, the admixture and the water are used as raw materials, magnesium oxide and polypropylene fibers are added on the basis, the optimal components and proportion are obtained through a proportion optimization method, the anti-crack concrete is prepared, the anti-crack performance, the waterproof performance and the impact resistance of the concrete are improved, and in the water conservancy and hydropower engineering, even if the concrete is impacted by water pressure, the concrete can still be prevented from cracking. And the generation of cracks can also be reduced.
本发明公开了建筑材料领域的一种抗裂混凝土及其配比优化方法，所述抗裂混凝土以kg/m3计，由以下原料组成，水132kg、水泥330kg、外加剂2.64kg、砂石755.44kg、细骨料493.02kg、粗骨料739.54kg、氧化镁0‑33kg和聚丙烯纤维0‑1.2kg。本方案以水泥、骨料、砂石、外加剂和水为原料，在其基础上添加氧化镁和聚丙烯纤维，通过配比优化方法获取最优成分及配比，以此制备抗裂混凝土，提高了混凝土的抗裂性能、防水性能和抗冲击性能，在水利水电工程中，即使受到水压冲击，也能够降低裂缝的产生。
