Anti-freezing concrete mixture and preparation method thereof
The invention relates to the technical field of concrete, in particular to an anti-freezing concrete mixture and a preparation method thereof, and the anti-freezing concrete mixture comprises the following components in parts by weight: 300-350 parts of cement; 100-150 parts of fly ash; 600-700 parts of sand; 800-1000 parts of fine stone; 200-250 parts of water; 4-6 parts of a water reducing agent; 4-6 parts of an early strength agent; and 30-40 parts of nano silicon dioxide modified polypropylene fiber. The preparation method comprises the following steps: S1, fully mixing the cement, the sand, the fine stone, the silica fume and the nano silicon dioxide modified polypropylene fiber to obtain a mixture A; s2, adding a water reducing agent and an early strength agent into water to obtain amixture B; s3, uniformly mixing the mixture A and the mixture B, and continuously stirring and mixing the mixtures to obtain the anti-freezing concrete mixture. The concrete prepared by the inventionhas good anti-freezing capability.
本申请涉及混凝土技术领域,尤其涉及一种抗冻混凝土拌合物及其制备方法，其包括如下重量份数的组分：水泥300‑350份；粉煤灰100‑150份；砂子600‑700份；细石800‑1000份；水200‑250份；减水剂4‑6份；早强剂4‑6份；纳米二氧化硅改性聚丙烯纤维30‑40份。其制备方法包括以下步骤：S1，将水泥、砂子、细石、硅灰和纳米二氧化硅改性聚丙烯纤维充分混合，得到混合物A；S2，将减水剂、早强剂加入水中，得到混合物B；S3，将混合物A和混合物B混合均匀，持续搅拌混合，即得抗冻混凝土拌合物。本申请制备的混凝土具有良好的抗冻能力。
