通过搅拌时间、投料顺序及养护对高泵送混凝土强度的影响做以分析,结果表明高泵送混凝土搅拌时间应介于120s~150s之间;二次投料搅拌混凝土各方面性能指标均优于传统一次投料搅拌,水泥裹石法对应的28d强度较一次搅拌强度提高到112%;混凝土湿养护时间不得小于7天,实际的施工中养护温度不应低于5℃。 Through the analysis of mixing time, feeding order and the influence of curing on the strength of high-pumping concrete, the results show that the mixing time of high-pumping concrete should be between 120s and 150s; the performance indexes of secondary mixing concrete are better than the traditional ones Once the material is mixed and stirred, the 28d strength corresponding to the cement-bound stone method is increased by 112% compared with the first mixing strength; the wet curing time of the concrete should not be less than 7 days; the actual curing temperature should not be lower than 5 ℃.
