High-durability rubber concrete and preparation method thereof
The invention discloses high-durability rubber concrete and a preparation method thereof. The concrete is prepared from the following raw materials in parts by weight: 400 to 800 parts of standard cement, 1000 to 1300 parts of coarse aggregate, 400 to 700 parts of fine aggregate, 0.5 to 2 parts of steel fiber, 3 to 12 parts of epoxy resin, 1.5 to 6 parts of curing agent, 1 to 5 parts of defoaming agent, 0.01 to 1 part of water reducing agent, 4 to 5 parts of composite nano material, 1 to 6 parts of silane coupling agent and 2 to 7 parts of polymer emulsion. The water-binder ratio of the rubber concrete is 0.40, the sand-binder ratio of the rubber concrete is 1.45, and the sand ratio of the rubber concrete is 32%. The advantages of the rubber particles, the epoxy resin and the steel fibers are combined, and the composite nanoparticles are added, so that the performance of the concrete is remarkably improved. The rubber particles provide good elasticity and toughness, so that the anti-cracking performance is remarkably improved, and the cracking risk of the concrete is reduced. The epoxy resin forms a firm three-dimensional network structure through a cross-linking reaction with the curing agent, the durability of the concrete is enhanced under the synergistic effect of the components, and the service life of the concrete is prolonged.
本发明公开了一种高耐久性橡胶混凝土及其制备方法。本发明包括如下重量份原料组成：基准水泥400—800份、粗骨料1000‑1300份、细骨料400‑700份、钢纤维0.5‑2份、环氧树脂3‑12份、固化剂1.5‑6份、消泡剂1‑5份、减水剂0.01‑1份、复合纳米材料4‑5份、硅烷偶联剂1‑6份、聚合物乳液2‑7份；所述橡胶混凝土的水胶比为0.40，砂胶比为1.45，砂率为32％。本发明将橡胶颗粒、环氧树脂和钢纤维三者的优势结合，并加入复合纳米颗粒，以显著提升混凝土的性能。橡胶颗粒提供了良好的弹性和韧性，显著提升了抗裂性能，减少了混凝土的开裂风险。环氧树脂通过与固化剂的交联反应，形成坚固的三维网状结构，各组分在协同作用下增强了混凝土的耐久性，延长了其使用寿命。
