The laboratory program consisted of casting 144 76 mm by 152 mm (3 x 6 in.) concrete cylinders and subjecting them to one of two levels of vibration for either I or 2 min at five different ages

2020-10-18 View. Show abstract Several investigators have studied the effect of different types of vibration on green concrete of different ages to suggest the safe vibration levels. the freshly placed
2019-6-13 view of the large variation of vibration resistance results, a factor of safety of 5 is recommended. Despite the use of a fairly large factor of safety, the vibration control limits investigate the short/long term effects of vibration on concrete; and (3) a theoretical study to correlate the vibration resistance of a concrete to its mechanical
al, concrete must be consolidated (compacted) by re-m o ving the entrapped air. Today most concrete is consolidated by vibration. Vi-b r ation subjects the fresh concrete to ve r y rapid impuls-es which tempora r ily liquefy the mixture (Fi g u r e 1) and cause the concrete level to subside. The entrapped air,
Vibration was generated by small scale blasting. The experimental results show that the blast induced vibration has negative and positive effects on the strength of the fresh concrete depending on the curing time at blasting. Vibration can increase the strength within the first 1-2 days.
