Effect of blasting vibration on quality of new laid concrete and control measures |
| |
| Abstract: | The quality of the new laid concrete is more easily influenced by the vibration due to the rock excavation blasting. In this paper, the monitoring results of blasting vibration effect on the new laid concrete for the Three Gorges Project are introduced. The causes for the over grade of vibration velocity are explored. The measures of preventing over grade of vibration velocity and controlling blasting vibration are proposed. |
