High-performance cold-resistant anti-freezing concrete and preparation method thereof
The invention discloses a high-performance cold-resistant anti-freezing concrete. The concrete comprises, by weight, 15-20 parts of stones; 15-20 parts of sands; 60-80 parts of cement; 8-12 parts of a mixing agent; 8-12 parts of an adhesive; 10-15 parts of a filling agent; and 30-40 parts of water. Large-particle-size stones are screened out, and it is avoided that after concrete is solidified, the large-particle-size stones are pressed, and gaps are generated between the large-particle-size stones and mixed materials. The stone and sand raw materials are washed and dried, impurities on the surfaces of the stone and sand are removed, and the adhesion strength of the stones and sands and the mixed material is improved. The mixing agent, the adhesive and the filling agent are proportioned, so that the stability and the strength of the solidified concrete are ensured, and low-temperature cracking is prevented.
本发明公开了一种高性能抗寒防冻混凝土，包括下述重量份数的组份：石子15‑20份；砂15‑20份；水泥60‑80份；混合剂8‑12份；粘合剂8‑12份；填充剂10‑15份；水30‑40份。本发明筛除了大粒径的石子，避免了混凝土凝固后大粒径石子受压与混料产生缝隙的。本发明对石子和砂原料进行冲洗烘干，去除了石子和砂表面的杂质，增加了石子和砂与混料的粘附强度。本发明的混合剂粘合剂和填充剂的配比，保证了混凝土凝固后的稳定性和强度，防止低温开裂。
