Anti-freezing concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses anti-freezing concrete and a preparation method thereof. The anti-freezing concrete comprises the following raw materials: 210-320 parts of cement, 760-900 parts of coarse aggregate, 520-660 parts of fine aggregate, 6-8 parts of a water reducing agent, 20-38 parts of a filler, and 120-180 parts of water, wherein the filler is prepared from the following raw materials in parts by weight: 15-30 parts of alpha aluminum oxide, 0.3-0.6 part of sodium fatty alcohol polyoxyethylene ether sulfonate, 0.7-1.4 parts of sodium heavy alkyl benzene sulfonate, and 4-6 parts of ethylene glycol. The preparation method comprises the following steps: S1, mixing and stirring alpha aluminum oxide, sodium fatty alcohol polyoxyethylene ether sulfonate, sodium heavy alkyl benzene sulfonate and ethylene glycol, and fully mixing to obtain a filler; mixing and stirring cement, coarse aggregate, fine aggregate and a water reducing agent, and fully mixing to obtain a first mixture; S2, adding the first mixture into water, fully stirring, and fully mixing to obtain a second mixture; and S3, adding the filler into the second mixture, and fully stirring to obtain the anti-freezing concrete. The anti-freezing concrete disclosed by the invention has the advantage of good anti-freezing performance.
本申请涉及混凝土领域，具体公开了一种抗冻混凝土及其制备方法。抗冻混凝土原料包括水泥210‑320份；粗骨料760‑900份；细骨料520‑660份；减水剂6‑8份；填料20‑38份；水120‑180份；所述填料由以下重量份的原料制成：α氧化铝15‑30份脂肪醇聚氧乙烯醚磺酸钠0.3‑0.6份；重烷基苯磺酸钠0.7‑1.4份；乙二醇4‑6份；其制备方法为：S1：将α氧化铝、脂肪醇聚氧乙烯醚磺酸钠、重烷基苯磺酸钠、乙二醇混合进行搅拌，充分混合得到填料；将水泥、粗骨料、细骨料、减水剂混合搅拌，充分混合得到第一拌合物；S2：将第一拌合物加入水中充分搅拌，充分混合得到第二拌合物；S3：将填料加入第二拌合物内充分搅拌，制得抗冻混凝土。本申请的抗冻混凝土，其具有抗冻性能好的优点。
