Concrete with high fracture resistance and fatigue resistance and preparation process thereof
The invention relates to the field of concrete preparation, in particular to high-fracture-resistance and fatigue-resistance concrete and a preparation process thereof, and the high-fracture-resistance and fatigue-resistance concrete is mainly prepared from the following raw materials in parts by weight: 120-150 parts of water, 100-130 parts of Portland cement, 50-100 parts of silica sand, 40-70 parts of fly ash, 50-70 parts of limestone, 30-50 parts of a rubber mixture, 0.5-1.5 parts of a silane coupling agent and 10-20 parts of a filler. The rubber mixture is composed of at least one of methyl vinyl silicone rubber and hydrogenated butadiene-acrylonitrile rubber and natural rubber according to a mass ratio of (3-5): 1. The high-fracture-resistance and fatigue-resistance concrete prepared by the invention has the advantage of improving the fracture resistance of the concrete.
本申请涉及混凝土制备领域，更具体地说，它涉及一种高抗折耐疲劳混凝土及其制备工艺，主要由以下重量份数的原料制成：水120‑150份，硅酸盐水泥100‑130份，硅砂50‑100份，粉煤灰40‑70份，石灰岩50‑70份，橡胶混合物30‑50份，硅烷偶联剂0.5‑1.5份，填充剂10‑20份；所用橡胶混合物为甲基乙烯基硅橡胶、氢化丁腈橡胶中的至少一种与天然橡胶按照质量比（3‑5）:1组成。本申请制备的高抗折耐疲劳混凝土具有提升混凝土抗折性能的优点。
