In the construction of tall-building, concrete pumping influences the success of the project. So, in order to apply the high strength concrete of 80MPa and 100MPa to super tall buildings of the vertical height of 600m above, the pumping trial test were conducted for the length of horizontal pipe 400m, 600m, 1200m distance. As a result, depending on the pumping distance, the pipe pressure showed a very large difference, and according to the properties of the concrete, the pipe pressure loss were different. In this paper, the conditions of the concrete mix, pressure loss and the change in the relationship between discharge amount of concrete were analyzed, and the results are presented. |
