Anti-freezing concrete and preparation method thereof
The invention relates to anti-freezing concrete and a preparation method thereof, the anti-freezing concrete is prepared from a concrete mixture, and the concrete mixture is prepared from the following raw materials in parts by weight: 130-150 parts of water, 620-640 parts of medium sand, 1000-1040 parts of modified mixed gravel, 250-270 parts of cement, 80-90 parts of fly ash, 40-50 parts of silicon powder, 8-10 parts of an air entraining agent and 3-7 parts of a polycarboxylate superplasticizer. The preparation method of the concrete comprises the following steps: step 1, uniformly mixing cement, fly ash, silicon powder and water to obtain cement slurry; step 2, uniformly mixing medium sand, the modified mixed gravel, an air entraining agent and a polycarboxylic acid water reducing agent with cement slurry to obtain a concrete mixture; and 3, pouring the concrete mixture into a mold, and carrying out standard curing to obtain the anti-freezing concrete. The concrete aggregate has the effects of improving the freezing resistance of the concrete aggregate and further improving the freezing resistance of the concrete.
本申请涉及一种抗冻混凝土及其制备方法，其由混凝土拌合料制得，混凝土拌合料包括以下重量份的原料：水130‑150份、中砂620‑640份、改性混合碎石1000‑1040份、水泥250‑270份、粉煤灰80‑90份、硅粉40‑50份、引气剂8‑10份、聚羧酸减水剂3‑7份。混凝土制备方法包括以下步骤：步骤1，将水泥、粉煤灰、硅粉和水混合均匀，得到水泥浆料；步骤2，将中砂、改性混合碎石、引气剂和聚羧酸减水剂同水泥浆料混合均匀，得到混凝土拌合料；步骤3，将混凝土拌合料倒入模具中进行标准养护，得到抗冻混凝土。本申请具有提升混凝土骨料的抗冻性，进而提升混凝土抗冻性的效果。
