Manufacturing method of part non-autoclaved concrete pipe pile
The invention provides a manufacturing method of a part non-autoclaved concrete pipe pile, which is prepared from the following raw materials: 450 to 500 kg/m <3> of PII52.5 R Portland cement, 650 to 700 kg/m <3> of machine-made sand, 45 to 50 kg/m <3> of microbeads, 90 to 100 kg/m <3> of mineral powder, 45 to 50 kg/m <3> of silica fume, 1100 to 1200 kg/m <3> of gravel, 12 to 15 kg/m <3> of a water reducing agent and 150 to 160 kg/m <3> of water. The method specifically comprises the steps of cage weaving, mold assembling, concrete mixing according to the proportion, filling, centrifugal forming, normal-pressure curing, demolding, detecting and the like. According to the manufacturing method of the non-autoclaved concrete pipe pile, by optimizing the formula of the PII52.5 R Portland cement, the machine-made sand, the microbeads, the mineral powder, the silica fume, the gravels, the water reducing agent and the water and optimizing the production process, the good mechanical property can be still kept on the premise that high-pressure steam curing is omitted, energy consumption can be saved. The dependence on natural sand resources can be reduced, and the production cost is reduced.
本发明提供了一种构件免蒸压混凝土管桩的制造方法，包括：它是由以下的原料制备而成：450‑500kg/m3的PⅡ52.5R的硅酸盐水泥，650‑700kg/m3的机制砂，45‑50kg/m3的微珠，90‑100kg/m3的矿粉，45‑50kg/m3的硅灰，1100‑1200kg/m3的碎石，12‑15kg/m3的减水剂，150‑160kg/m3的水，具体包括编笼、组模、按照配比搅拌混凝土料、装填、离心成型、常压养护、脱模、检测等步骤。本构件免蒸压混凝土管桩的制造方法，通过对PⅡ52.5R的硅酸盐水泥、机制砂、微珠、矿粉、硅灰、碎石、减水剂和水的配方优化，以及生产工艺的优化，可以在免除高压蒸汽养护的前提下依旧保持良好的力学性能，不仅可以节约能耗，而且可以减少对天然砂资源的依赖，降低生产成本。
