- Abstract
In the flow of fluid in pipeline, the pressure drop in a curved pipe is generally greater than that in a straight pipe. Several studies have been conducted on the quantitative prediction of concrete pumping using the rheological properties of concrete and lubricating layer. However, there have not been many studies to quantitatively investigate the pressure loss in a pipe bend. In this study, the effects of pressure loss by the pipe bends were investigated through realscale concrete pumping tests. The real-scale pumping tests were performed for horizontal pipelines of 133, 369, and 560 m (145, 404, and 612 yd), and a total of four concrete mixtures were used for tests. In addition, the data obtained from previous pumping tests with 350 and 548 m (383 and 599 yd) horizontal pipelines were also analyzed. From the tests and analysis, it was found that the pressure loss in pipe bends is greater than the straight pipeline by approximately two times.
