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

Choosing a concrete vibrator

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,

Effects of blast induced vibrations on the fresh

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.
