Abstract
In this study, the authors proposed an evaluation method of concrete pumpability using vibration acceleration as a technique that allows easy direct check of the concrete pumping condition at the construction site. This method indicates that it is possible to evaluate concrete pumpability based on past experiment results. However, studies on various piping routes and how to evaluate measurement results are insufficient.
In this study, concrete was pumped at an actual construction site under four kinds of special piping routes, measurement was made with vibration acceleration and the evaluation method was reviewed based on the measurement results.
The results confirmed that the measurements of acceleration are completely different depending on the piping routes and the measurement position in each condition. The threshold amount of pumpability evaluation using measured acceleration values is also determined.
