Environment-friendly anti-freezing concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses environment-friendly anti-freezing concrete and a preparation method thereof. The environment-friendly anti-freezing concrete is prepared from the following components in parts by weight: 420 to 570 parts of cement, 572 to 656 parts of sand, 825 to 940 parts of stone, 170 to 210 parts of water, 51 to 70 parts of admixture, 58.8 to 80.6 parts of admixture, 40 to 60 parts of waste rubber particles and 45 to 60 parts of anti-freezing agent, the anti-freezing agent comprises the following components: modified starch, graphene oxide, iron tailing powder, eggshell membrane, sodium hydroxide, urea and cellulose; the preparation method comprises the following steps: adding the admixture and the antifreeze agent into water, and uniformly mixing to obtain a premix; mixing the cement, the sand, the stones, the admixture and the waste rubber particles, adding the premix, and uniformly mixing to obtain the environment-friendly anti-freezing concrete. The environment-friendly anti-freezing concrete has the advantages that waste rubber is recycled, the anti-freezing performance and the anti-seepage performance are high, and automobile exhaust can be purified.
本申请涉及建筑材料技术领域，具体公开了一种环保抗冻混凝土及其制备方法。环保抗冻混凝土包括以下重量份的组分：水泥420‑570、砂子572‑656、石子825‑940份、水170‑210份、掺合料51‑70份、外加剂58.8‑80.6份、废旧橡胶颗粒40‑60份、抗冻剂45‑60份；抗冻剂包括以下组分：改性淀粉、氧化石墨烯、铁尾矿粉、蛋壳膜、氢氧化钠、尿素、纤维素；其制备方法为：将外加剂和抗冻剂加入水中，混合均匀，得预混料；将水泥、砂子、石子、掺合料和废旧橡胶颗粒混合，加入预混料，混合均匀，得环保抗冻混凝土。本申请的环保抗冻混凝土具有回收利用废旧橡胶，抗冻、抗渗性能强，能净化汽车尾气的优点。
