Impermeable wear-resistant concrete and preparation method thereof
The invention relates to the field of building materials, and discloses impermeable wear-resistant concrete and a preparation method thereof. The concrete comprises the following raw materials by weight: 200-350 parts of recycled concrete, 50-75 parts of slag powder, 50-75 parts of fly ash, 600-650 parts of broken stone, 5-6 parts of straw, 4-5 parts of disodium lauryl sulfosuccinate, 2-3 parts ofepoxypropyl acrylate, and 0.2-0.4 part of an emulsifier. Compared with the prior art, the impermeable wear-resistant concrete and the preparation method thereof in the invention has the following advantages and effects: in the presence of the emulsifier, disodium lauryl sulfosuccinate and epoxypropyl acrylate are mixed to obtain polymer particles with small particle sizes and enhance the stability of the particles, the microstructure of the concrete is improved, a water cement ratio can be properly reduced due to surface activity effect, the concrete is denser, and the impermeability of the concrete is improved, and hydrogen bonds are easily formed between carboxyl groups of disodium lauryl sulfosuccinate and glycidyl acrylate, and the obtained polymer phase can fill in part of capillarypores and other gaps in the concrete after the concrete is hardened, so the impermeability and the wear resistance of the concrete are improved.
本申请涉及建筑材料的领域，公开了一种抗渗耐磨混凝土及其制备方法，混凝土包括如下重量份数的原料：200‑350份再生混凝土；50‑75份矿渣粉；50‑75份粉煤灰；600‑650份碎石；5‑6份稻草；4‑5份月桂醇磺基琥珀酸酯二钠；2‑3份丙烯酸环氧丙酯；0.2‑0.4份乳化剂。本申请具有以下优点和效果：在乳化剂存在条件下，月桂醇磺基琥珀酸酯二钠和丙烯酸环氧丙酯混合可得到粒径较小的聚合物微粒并增强粒子稳定性，有助于改善混凝土的微观结构，表面活性作用可适当减小水灰比，使混凝土更趋密实，提高抗渗性；月桂醇磺基琥珀酸酯二钠和丙烯酸环氧丙酯的羧基基团之间易形成氢键，得到的聚合物相可在混凝土硬化后填充混凝土内的部分毛细孔和其他空隙，提高混凝土的抗渗性和耐磨性。
