Anti-freezing concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses anti-freezing concrete and a preparation method thereof.The anti-freezing concrete is prepared from, by weight, 190-210 parts of cement; 50 to 70 parts of mineral powder; 25 to 35 parts of fly ash; 55-65 parts of stone powder; 600 to 610 parts of machine-made sand; 270 to 290 parts of river sand; 950 to 1050 parts of broken stone; 8-10 parts of a pumping agent; 20 to 40 parts of modified steel fibers; and 160 to 180 parts of water; and the modified steel fibers are steel fibers with the surfaces coated with polypropylene layers. By adding the modified steel fibers, the effect of improving the frost resistance and compressive strength of the concrete is achieved.
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，抗冻混凝土由包含以下重量份的原料制成：水泥190‑210份；矿粉50‑70份；粉煤灰25‑35份；石粉55‑65份；机制砂600‑610份；河砂270‑290份；碎石950‑1050份；泵送剂8‑10份；改性钢纤维20‑40份；水160‑180份；所述改性钢纤维是指表面包覆有聚丙烯层的钢纤维。本申请通过加入改性钢纤维，具有提高混凝土的抗冻性能和抗压强度的效果。
