Machine-made sand concrete construction method
The invention discloses a construction method of machine-made sand concrete. The construction method comprises the following steps: preparing the machine-made sand concrete; preparing a regulator of the machine-made sand concrete; mixing zigzag steel fibers and polyethylene fibers to obtain mixed fibers; the method comprises the following steps: mixing 45-60 parts by mass of cement, 30-42 parts by mass of fly ash, 140-150 parts by mass of machine-made sand and 78-95 parts by mass of gravel, adding a polycarboxylic acid water reducer and water, continuously stirring and mixing, finally adding 0.5-0.9 part by mass of a regulator, and stirring for 2 hours to obtain the machine-made sand concrete. Transportation of the machine-made sand concrete: adopting a concrete mixer for transportation; pouring the machine-made sand concrete: before pouring, checking that the water-binder ratio of the machine-made sand concrete meets the water-binder ratio of the machine-made sand concrete, and then pouring; and maintaining the machine-made sand concrete. According to the construction method, the ratio of the machine-made sand is optimized, the impermeability and compressive strength of the machine-made sand concrete are improved, the toughness is enhanced, and the bleeding rate is reduced.
本发明公开了机制砂混凝土施工方法，包括：机制砂混凝土的制备：机制砂混凝土的调节剂制备：将锯齿形钢纤维和聚乙烯纤维混合得混合纤维；将水泥45～60质量份、粉煤灰30～42质量份、机制砂140～150质量份、碎石78～95质量份混合，加入聚羧酸减水剂和水，继续搅拌混合，最后加入调节剂，掺入量为0.5～0.9质量份，搅拌2小时制得机制砂混凝土；机制砂混凝土的运输：采用混凝土搅拌机运输；机制砂混凝土的浇筑：浇筑前检查机制砂混凝土的水胶比符合步骤机制砂混凝土的水胶比后方可进行浇筑；机制砂混凝土的养护。本发明施工方法优化机制砂的配比，提高了机制砂混凝土的抗渗性能、抗压强度，增强了韧性，降低了泌水率。
