Corrosion-resistant concrete and preparation method thereof
The invention relates to the field of building materials, and discloses corrosion-resistant concrete and a preparation method thereof. The concrete comprises the following raw materials in parts by weight: 400 to 430 parts of quartz sand, 250 to 260 parts of recycled concrete, 70 to 75 parts of fly ash, 5 to 10 parts of straw, 18 to 20 parts of an acrylate emulsion, 10 to 12 parts of ethylene glycol distearate, 6 to 8 parts of sodium aluminum silicate, and 130 to 150 parts of water. The preparation method comprises the following steps: S1 mixing the raw materials; and S2 carrying out concrete steam curing. The invention has the following advantages and effects: sodium aluminum silicate contains Si-O-Al-O bonds with high bond energy, acidic compounds and the like are not easy to break, and the corrosion resistance and mechanical properties of concrete can be improved; the acrylate emulsion and ethylene glycol distearate polymer can be distributed in macropores and microcracks, and the emulsion polymer containing carboxyl groups forms oxyhydrogen bonds under the action of water, so that the emulsion polymer with corrosion resistance is adsorbed at the pores and microcracks to form a compact structure, thereby enhancing the corrosion resistance and mechanical properties; and the recycled concrete is adopted, which is more environment-friendly.
本申请涉及建材领域，公开了一种耐腐蚀混凝土及其制备方法。混凝土包括如下重量份数的原料：400‑430份石英砂；250‑260份再生混凝土；70‑75份粉煤灰；5‑10份稻草；18‑20份丙烯酸酯乳液；10‑12份乙二醇二硬脂酸酯；6‑8份硅酸铝钠；130‑150份水；制备方法为：S1.原料混合；S2.蒸养混凝土；本申请具有以下优点和效果：硅铝酸钠中含有键能较高的Si‑O‑Al‑O键，酸性化合物等不易使其产生断裂，可提高混凝土的耐腐蚀性及力学性能；丙烯酸酯乳液和乙二醇二硬脂酸酯的聚合物可分布于大孔隙和微裂缝中，此时含有羧基基团的乳液聚合物在水的作用下形成氢氧键，使具有抗腐蚀作用的乳液聚合吸附于孔隙和微裂缝处，形成致密结构，提升耐腐蚀性及力学性能；采用再生混凝土，更绿色环保。
