Abstract：
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.
