The invention provides an anti-freezing concrete regeneration process which comprises the following steps of S1, pretreatment, S2, magnetic screening, S3, crushing treatment, S4, mixing and S5, forming. The invention further provides an anti-freezing concrete, which comprises the following components in parts by mass: 55-65 parts of mortar powder, 10-15 parts of Portland cement, 2-5 parts of fly ash, 2-5 parts of bentonite, 10-15 parts of water-based BOPP resin, 5-10 parts of water, 0.5-1.5 parts of an anti-freezing agent and 0.5-1.5 parts of a water reducing agent. The anti-freezing concretehas the advantages of being anti-freezing, anti-cracking, high in stability and the like, and the phenomena of cracking, crisping and water seepage caused by repeated thawing and freezing of the concrete due to temperature difference change can be effectively avoided.
本发明提供了一种防冻混凝土再生工艺，包括以下步骤，S1：预处理、S2：磁筛、S3：破碎处理、S4：混合、S5：成型。本发明还提供了一种防冻混凝土配方，包括以下质量份数的组分：55‑65份砂浆粉体，10‑15份硅酸盐水泥，2‑5份粉煤灰，2‑5份膨润土，10‑15份水性BOPP树脂，5‑10份水，0.5‑1.5份防冻剂，0.5‑1.5份减水剂。本发明的防冻混凝土具有防冻、抗龟裂、稳定性高等优点，可有效解决由于温差变化导致混凝土反复融冻造成的裂纹、变酥、渗水现象。
