为满足低强度等级和高强度等级混凝土超高层泵送的特殊施工要求,通过三种不同类型的流变剂研究混凝土拌合物的流动性、粘度和填充性,通过坍落度、坍落扩展度、V型漏斗通过时间和T50测试手段,评价流变剂对拌合物的调节性能,结果表明HJ流变剂适宜低强度等级混凝土,6A流变剂适宜高强度等级自密实混凝土.%To meet the low strength grade and high strength grade of high-rise pumping special construction requirements, this article mainly through three different types of rheological agent research concrete mixture, viscosity and filling liquid, through the slump, the slump spread, V funnel through time and T50 test method, evaluation of rheological agent to the regulation performance of mixture, the results show that the HJ rheological agent suitable for low strength grade of concrete, 6A level of rheological agent is suitable for high strength self-compacting concrete.
