| 要旨 | The aim of this study is to evaluate and analyze the influence of pumping on property changes of concrete. The high-performance concrete with 80 MPa made up of various materials including a high retention type polycarboxylate-based superplasticizer was fabricated and placed to the 260 m height. Test results indicated that different changes in concrete properties were evaluated depending on the pumping height. Based on a rheological analysis, plastic viscosity was significantly decreased, and yield stress was slightly decreased. |
