Concrete formula for tubular pile with low curing period and forming and curing process thereof
The invention discloses a concrete formula for a pipe pile with a low curing period and a forming and curing process of the concrete formula. The concrete formula comprises 420-460 kg/m <3> of cement, 100-180 kg/m <3> of mineral admixture, 900-1100 kg/m <3> of coarse aggregate, 500-700 kg/m <3> of fine aggregate, 4-6 kg/m <3> of water reducing agent, 3-5 kg/m <3> of early strength agent and 5-7 kg/m <3> of aluminum powder. According to the concrete formula for the pipe pile with the low curing period and the forming and curing process of the concrete formula, a microwave heating mode can be efficiently utilized, under the condition that the mechanical property of the concrete is guaranteed, the required curing period is remarkably shortened, and meanwhile the influence of microwave curing on the porosity and microcracks can be reduced to the minimum.
本发明公开了低养护周期的管桩用混凝土配方及其成型与养护工艺，所述配方包括水泥420～460kg/m3、矿物掺合料100～180kg/m3、粗集料900～1100kg/m3、细集料500～700kg/m3、减水剂4～6kg/m3、早强剂3～5kg/m3以及铝粉5～7kg/m3；该低养护周期的管桩用混凝土配方及其成型与养护工艺能够高效利用微波加热的方式，在保障混凝土力学性能的情况下，显著减少所需养护的周期，同时能够将微波养护对孔隙率和微裂纹的影响降到最低。
