Environment-friendly anti-freezing concrete and preparation method thereof
The invention relates to environment-friendly anti-freezing concrete and a preparation method thereof.The environment-friendly anti-freezing concrete is prepared from, by weight, 170-250 parts of cement, 700-850 parts of artificial sand, 920-1100 parts of pebbles, 300-420 parts of water, 70-100 parts of additional powder, 2.5-4.5 parts of air entraining agent, 4.5-6 parts of water reducing agent and 70-90 parts of reinforced fibers; the reinforced fibers comprise a plurality of hollow fibers and a plurality of steel wires; the plurality of hollow fibers and the plurality of steel wires are arranged in a bundle shape and spirally wound; the preparation method of the environment-friendly anti-freezing concrete comprises the following steps: uniformly mixing the cement, the stones and the artificial sand, adding the dissolved and diluted water reducing agent and air entraining agent, adding the reinforced fibers, supplementing the residual formula amount of water, and stirring to obtain aconcrete slurry. The environment-friendly anti-freezing concrete has the effect of good anti-freezing effect.
本申请涉及一种环保抗冻型混凝土及其制备方法，一种环保抗冻型混凝土，按重量份计，包括水泥170‑250份、人工砂700‑850份、石子920‑1100份、水300‑420份、外加粉料70‑100份、引气剂2.5‑4.5份、减水剂4.5‑6份、强化纤维70‑90份；强化纤维包括若干中空纤维和若干钢丝；若干中空纤维与若干钢丝呈束状排布，并螺旋缠绕；一种环保抗冻型混凝土的制备方法：先将水泥，石子，人工砂拌和均匀后加入经过溶解稀释的减水剂与引气剂，然后加入强化纤维并补足剩余配方量的水后，搅拌制得混凝土料浆。本申请具有抗冻效果好的效果。
