Freezing-resistant plateau concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to freezing-resistant plateau concrete and a preparation method thereof.The freezing-resistant plateau concrete is prepared from 30-35 parts of cement, 50-60 parts of coarse aggregate, 100-110 parts of fine aggregate, 10-14 parts of filler, 0.8-1 part of water reducing agent and 1.5-2 parts of air entraining agent, the Portland cement is a hydraulic cementing material prepared by mixing and grinding Portland cement clinker, 5-20% of a mixed material and a proper amount of gypsum, and according to the invention, through the arrangement of the cement, the coarse aggregate, the fine aggregate, the filler, the water reducer, the air entraining agent and other ingredients, the elasticity of the rubber particles in the filler is matched with the fly ash, so that the remaining gaps can be further filled; the concrete has the advantages that liquid entering space is reduced as much as possible, freezing and thawing in the concrete are avoided, expansion and shrinkage of the concrete can be adapted, the basalt anti-crack fibers can position the rubber particles, the rubber particles are kept at uniform pouring positions, the strength of the concrete can be improved, and the resistance of the concrete to tensile stress is improved.
本发明涉及混凝土技术领域，尤其为一种耐冻高原混凝土及其制备方法，包括如下的组分：水泥30‑35份、粗骨料50‑60份、细骨料100‑110份、填充物10‑14份、减水剂0.8‑1份、引气剂1.5‑2份，所述水泥为硅酸盐水泥，所述硅酸盐水泥为硅酸盐水泥熟料、5％～20％的混合材料、适量石膏混合磨细制成的水硬性胶凝材料，本发明中，通过设置的水泥、粗骨料、细骨料、填充物、减水剂、引气剂等配料使填充物中橡胶粒的弹性配合粉煤灰可以进一步对剩余空隙进行填充，尽可能减少液体进入的空间，避免混凝土内出现冻融现象，且能够适应混凝土的膨胀收缩，而玄武岩抗裂纤维可以对橡胶粒进行定位，使橡胶粒保持在均匀浇注的位置，同时可以改善混凝土的强度，提高混凝土对拉应力的抵抗能力。
