Effect of Vibration on Concrete Mixtures
While vibration of concrete is everyday practice to assist with consolidation of the mixture, the fundamentals behind selecting the parameters that can be varied are not well understood. There is a need to investigate the effects of changing frequency and amplitude on: how a variety of mixtures will flow under vibration, the stability of air bubbles of different sizes (leading to loss of air), effect of excess vibration on water movement in the form (leading to honeycombing) and effects of chemical admixtures on these behaviors. Other variables to be considered include duration of vibration, aggregate type, mixture workability and SCM type and dose.
