Concrete formula for high-strength pipe pile and mixing and curing process thereof
The invention discloses a concrete formula for a high-strength tubular pile and a mixing and curing process thereof. The formula comprises 380-430 kg/m <3> of cement, 80-150 kg/m <3 > of a mineral admixture, 1100-1300 kg/m <3> of coarse aggregate, 400-500 kg/m <3> of fine aggregate, 6-8 kg/m <3> of a water reducing agent and 1-2 kg/m <3> of polyethylene particles or polystyrene particles, and the polyethylene particles or polystyrene particles contain reinforced fibers. According to the concrete formula for the high-strength tubular pile and the mixing and curing process of the concrete formula, the sand consumption and the water consumption can be reduced, meanwhile, the concrete has good flowability, the strength and the toughness of the tubular pile are improved, and meanwhile, the pore defects in the tubular pile are reduced.
本发明公开了高强度管桩用混凝土配方及其拌合与养护工艺，所述配方包括水泥380～430kg/m3、矿物掺合料80～150kg/m3、粗集料1100～1300kg/m3、细集料400～500kg/m3、减水剂6～8kg/m3以及聚乙烯颗粒或聚苯乙烯颗粒1～2kg/m3，所述聚乙烯颗粒或聚苯乙烯颗粒内含有增强纤维；该高强度管桩用混凝土配方及其拌合与养护工艺能够在减少用砂量和用水量的同时，还使混凝土具有良好的流动性，并提高管桩的强度和韧性，同时减少管桩内部的孔隙缺陷。
