The invention relates to the technical field of concrete, and particularly discloses high-performance anti-freezing concrete, which is prepared from the following raw materials in parts by weight: cement, water, mineral powder, gravel, sand, fly ash, a water reducing agent, magnesium lithium silicate, polypropylene fibers and polyvinylidene chloride copolymer emulsion. The preparation method comprises the following steps: preparing a water glue dispersion liquid A: mixing and stirring 2/5 of water in the raw materials and magnesium lithium silicate; preparing a mixture: stirring cement, mineral powder, gravel, sand and fly ash, then adding polypropylene fiber, stirring, adding a water reducing agent and 2/5 of water, and stirring to obtain the mixture; and preparing concrete: adding the water glue dispersion liquid A and the residual water into the mixture, stirring, finally adding polyvinylidene chloride copolymer emulsion, and stirring to obtain the concrete. According to the invention, the anti-freezing performance of the concrete is specifically improved while the strength is not reduced, and even the compressive strength can be further improved.
本申请涉及混凝土的技术领域，具体公开了一种高性能抗冻混凝土，该混凝土由包含以下重量份的原料制得：水泥、水、矿粉、碎石、砂、粉煤灰、减水剂、硅酸镁锂、聚丙烯纤维和聚偏二氯乙烯共聚乳液；其制备方法包括以下步骤：水胶分散液A制备：取原料中2/5的水与硅酸镁锂混合搅拌；混合料制备：将水泥、矿粉、碎石、砂和粉煤灰搅拌，然后加入聚丙烯纤维，搅拌，加入减水剂和2/5的水，搅拌，得到混合料；混凝土制备：在混合料中加入水胶分散液A以及剩余的水，搅拌，最后加入聚偏二氯乙烯共聚乳液，搅拌，即得。本申请具体提高混凝土抗冻性性能的同时，不会降低强度，甚至可以进一步提高其抗压强度。
