The invention relates to self-compacting freeze-thaw-resistant concrete. The concrete is prepared from, by weight, 110-150 parts of water, 50-150 parts of cement, 10-15 parts of nanometer silicon dioxide, 80-100 parts of waste gas concrete powder, 10-20 parts of slag steel, 5-10 parts of water glass, 5-10 parts of fine aluminum powder, 5-10 parts of bentonite, 5-10 parts of gypsum, 5-10 parts of quick lime, 20-30 parts of fine river sand, 2-4 parts of a defoaming agent, 1-3 parts of a thickening agent and 1-3 parts of a retarder. According to the invention, the waste gas concrete powder, slagsteel and cement form new concrete, so the cement consumption can be reduced, and the concrete production cost is reduced; and the waste gas concrete powder slag steel is compounded and doped into theconcrete, and the two mixed materials complement each other, so that the advantages and complementary effects of the waste gas concrete powder slag steel can be brought into full play, the structuralstrength performance of the concrete can be effectively improved, the cement hydration temperature peak of the concrete can be reduced, and the durability of the concrete can be improved.
本发明涉及一种自密实抗冻融混凝土，按重量份数计，其原料包括水110‑150份、水泥50‑150份、纳米二氧化硅10‑15份、废气混凝土粉末80‑100份、渣钢10‑20份、水玻璃5‑10份、细铝粉5‑10份、膨润土5‑10份、石膏5‑10份、生石灰5‑10份、细河沙20‑30份、消泡剂2‑4份、增稠剂1‑3份、缓凝剂1‑3份。本发明将废气混凝土粉末、渣钢和水泥组成新的混凝土，不仅可减少水泥用量，降低混凝土生产成本，而且将废气混凝土粉末渣钢复合掺入混凝土后，水化过程会互相激发而产生复合胶凝效应，两种混合材料取长补短可充分发挥废气混凝土粉末渣钢的优势和互补作用，可有效的提高混凝土的结构强度性能，可降低混凝土水泥水化温峰，提高混凝土耐久性。
