High-durability concrete
The invention discloses high-durability concrete, and relates to the technical field of building engineering construction, and each cubic meter of the concrete comprises the following raw materials: 273-293 kg/m < 3 > of cement, 340-450 kg/m < 3 > of a cementing material, 703-710 kg/m < 3 > of sand, 1064-1099 kg/m < 3 > of stone, 9.66-10.35 kg/m < 3 > of an additive, 0.9-1.2 kg/m < 3 > of polypropylene fiber and the balance of water. The cementing material comprises 105-113kg/m < 3 > of fly ash, 42-45kg/m < 3 > of S95 mineral powder and 29-32kg/m < 3 > of a waterproof agent; according to the scheme, the sulfate corrosion resistance, the early-stage crack resistance and the chloride ion penetration resistance of the concrete are improved by preparing the concrete combination proportion, and the durability of the concrete is enhanced.
本发明公开了一种高耐久混凝土，涉及建筑工程施工技术领域，每立方所述混凝土的原料配比包括：水泥273～293kg/m3、胶凝材料总量为340～450kg/m3、砂703～710kg/m3、石1064～1099kg/m3、外加剂9.66～10.35kg/m3、聚丙烯纤维0.9～1.2kg/m3和余量水；所述胶凝材料包括粉煤灰105～113kg/m3、S95矿粉42～45kg/m3和防水剂29～32kg/m3；采用本方案，通过制备混凝土组合配比，提高了混凝土的抗硫酸盐侵蚀性能、早期抗裂缝性能和抗氯离子渗透性能，增强了自身耐久性。
