Impermeable concrete suitable for severe cold areas and preparation method thereof
The invention discloses impermeable concrete suitable for severe cold areas and a preparation method thereof.The impermeable concrete is prepared from 300-350 parts of cement, 80-130 parts of admixture, 720-820 parts of sand, 810-830 parts of stone, 160-180 parts of water and an impermeable anti-freezing agent, the impermeable anti-freezing agent comprises basalt fibers, modified polyester fibers, steel fibers, nano-silica with the average particle size smaller than 100 nm and a water reducing agent, the total amount of the basalt fiber, the modified polyester fiber and the steel fiber is 28-80 parts, the dosage of the nano silicon dioxide is 3-5 parts, and the dosage of the water reducing agent is 8-10 parts. The concrete system prepared by the invention is high in anti-permeability, high in compressive strength, low in anti-permeability and freeze-thaw loss rate and excellent in performance.
本发明公开了一种适用于严寒地区的抗渗混凝土及其制备方法，包括：水泥300～350份、掺合料80～130份、砂720～820份、石810～830份、水160～180份和抗渗防冻剂，抗渗防冻剂包括玄武岩纤维、改性聚酯纤维、钢纤维、平均粒径小于100nm的纳米二氧化硅和减水剂，玄武岩纤维、改性聚酯纤维和钢纤维的总量为28～80份，纳米二氧化硅的用量为3～5份，所述减水剂的用量为8～10份。本发明制备的混凝土体系，抗渗性能强、抗压强度高、抗渗能力、抗冻融损失率低，性能优异。
