The invention relates to the technical field of concrete, and particularly discloses freeze-thaw resistant concrete. A mixture of the freeze-thaw resistant concrete is prepared from the following components in parts by weight: 1200 to 1260 parts of coarse aggregate, 680 to 700 parts of fine aggregate, 180 to 220 parts of modified steel slag particles, 260 to 280 parts of Portland cement, 104 to 112 parts of water and 2.6 to 2.8 parts of polycarboxylic acid water reducing agent, wherein the modified steel slag particles are steel slag aggregate with paraffin adsorbed on the surface. The modified steel slag particles play a foam stabilizing role, bubbles generated by the polycarboxylate superplasticizer are collected and stored, breakage of the bubbles is reduced, the actual gas content of the concrete can be increased, and the freeze-thaw resisting effect of the concrete is improved.
本申请涉及混凝土技术领域，具体公开了一种抗冻融混凝土。所述抗冻融混凝土的拌和物包括如下重量份的组分：粗骨料1200‑1260份，细骨料680‑700份，改性钢渣颗粒180‑220份，硅酸盐水泥260‑280份，水104‑112份，聚羧酸减水剂2.6‑2.8份，所述改性钢渣颗粒为表面吸附有石蜡的钢渣骨料。本申请通过改性钢渣颗粒发挥稳泡作用，对聚羧酸减水剂促生的气泡进行了收集和储存，减少了气泡的破裂，有助于增加混凝土的实际含气量，改善了混凝土的抗冻融效果。
