The invention discloses anti-freezing and anti-cracking concrete, which is prepared from the following components in parts by weight: 310 to 400 parts of ordinary Portland cement, 1100 to 1300 parts of coarse aggregate, 400 to 600 parts of fine aggregate, 240 to 260 parts of water, 15.5 to 20 parts of anti-freezing agent, 3 to 4 parts of water reducing agent and 1.2 to 1.5 parts of anti-cracking fiber. Compared with the prior art, the method has the advantages that the concrete produced by adopting the method has high-strength anti-freezing and anti-cracking performance, and meanwhile, through mixing and stirring production of various coarse aggregates and various fine aggregates, the quality and the strength of the concrete are guaranteed, the production cost is greatly reduced, and the concrete is suitable for large-scale production. The device is suitable for being popularized and used for producing concrete.
本发明公开了一种抗冻抗开裂混凝土，它重量配比包括普通硅酸盐水泥310‑400份、粗骨料1100‑1300份、细骨料400‑600份、水240‑260份、防冻剂15.5‑20、减水剂3‑4份，抗裂纤维1.2‑1.5份。本发明与现有技术相比的优点在于：采用本方法生产出来的混凝土具有高强度的抗冻抗开裂性能，同时通过了多种粗骨料和多种细骨料混合搅拌生产，即保证了混凝土的质量和强度，还大大降低了生产成本，适宜推广使用本发明进行生产混凝土。
