Anti-freezing concrete and preparation method thereof
The invention discloses a preparation method of anti-freezing concrete, which comprises the following steps: firstly, putting cement, gravel and rubber aggregate into a concrete mixer according to a ratio of 2: 1: 1, starting the concrete mixer to dry-mix the materials so as to uniformly mix, uniformly stirring water and a polycarboxylate superplasticizer in a weighing container according to a ratio of 2: 1, and uniformly mixing to obtain a mixture; the preparation method comprises the following steps: slowly adding a mixed solution of water and a polycarboxylate superplasticizer into a stirrer in two times until a uniform concrete mixture is formed, finally, stopping stirring, and pouring out a fully stirred and uniform material. The rubber aggregate is doped into the concrete, so that the toughness, freezing resistance, impact resistance, wear resistance, fatigue resistance and other properties of the concrete can be remarkably improved, the freezing resistance of the concrete can be greatly improved, the stable quality of the concrete can be ensured, and the concrete has a wide application prospect in plateau alpine regions.
本发明公开了一种抗冻混凝土的制备方法，包括以下步骤，首先，将水泥、砂石和橡胶集料按2：1：1比例投入混凝土搅拌机中，启动混凝土搅拌机使物料干拌，以便混合均匀，将水和聚羧酸减水剂按2：1比例在称量容器中搅拌均匀，将水和聚羧酸减水剂混合液分两次缓慢加入到搅拌机里，直至形成均匀的混凝土拌合物，最后，停止搅拌，倒出充分搅拌且均匀的物料，本发明一种抗冻混凝土及其制备方法，混凝土中掺入橡胶集料可以显著提高混凝土的韧性、抗冻性、抗冲击性、耐磨和抗疲劳性等性能，不仅可以大幅提升混凝土的抗冻性，而且可以保证混凝土质量稳定，这使得混凝土在高原高寒地区具有广阔的应用前景。
