A Study on the Pumping Characteristics according to Pumping Method and Rheology Characteristics of Concrete

콘크리트의 레올로지 특성 및 펌핑조건에 따른 펌프압송특성에 관한 연구

In order to have pumping technology for high speed construction of tall building, study for quantitative evaluation of flow characteristics and pumpability should be conducted. So, this study evaluate the characteristics among the inner pipe pressure, fresh concrete properties and separated mortar through the continuous pumping test. Then it consider of relations between rheological properties and pumpability. In the result of test, it found that there are high interrelationship between the rheological characteristics which represented plastic viscosity and pressure lose by pipe length.
