The invention relates to the field of concrete, and particularly discloses anti-freezing concrete and a preparation method thereof. The anti-freezing concrete is composed of the following components in parts by weight: 30 to 35 parts of Portland cement, 15 to 20 parts of water, 32 to 45 parts of sand, 46 to 55 parts of pebbles, 13 to 22 parts of filler, 0.8 to 1.2 parts of a water reducing agent, 3 to 5 parts of anti-crack fibers, 8 to 15 parts of rubber particles, 0.5 to 1 part of a waterproof agent, 0.1 to 0.3 part of an anti-freezing agent and 0.3 to 0.6 part of an air entraining agent, wherein the surface of the concrete is coated with a surface reinforcing agent. The anti-crack fibers in the concrete can improve the crack resistance of the concrete and reduce cracks, so that water permeation is reduced; the rubber particles and the anti-crack fibers can improve the elastic modulus of the concrete, the air entraining agent introduces air holes in the concrete, frost heaving pressure can be buffered, and freeze-thaw damage can be reduced; and the waterproof agent has a waterproof effect, and the anti-permeability is improved, so moisture infiltration is reduced, and the freeze-thaw resistance is improved.
本申请涉及混凝土领域，具体公开了一种抗冻混凝土及其制备方法。一种抗冻混凝土包括以下重量份的组分：30‑35份硅酸盐水泥、15‑20份水、32‑45份砂子、46‑55份石子、13‑22份填料、0.8‑1.2份减水剂、3‑5份抗裂纤维、8‑15份橡胶颗粒、0.5‑1份防水剂、0.1‑0.3份防冻剂、0.3‑0.6份引气剂，混凝土表面涂有表面增强剂。本申请的混凝土中抗裂纤维能提高混凝土的抗裂性，减少裂缝产生，从而减少水分渗入，橡胶颗粒和抗裂纤维能提高混凝土的弹性模量，引气剂在混凝土内引入气孔，均能够缓冲冻胀压力，减少冻融破坏，防水剂具有防水效果，增加抗渗性，从而减少水分渗入，进而提高抗冻融性能。
