VIBRATED CONCRETE
The article examines the ways in which handling methods can reduce concrete quality and how this can be corrected using vibration techniques. The transportation of concrete can result in gravitation of aggregate so that fines tend to be discharged first. This segregation can be corrected while the concrete is being vibrated and, during this fluid stage, the concrete is likely to regain its original characteristics. The object of vibrating concrete is to assist in its compaction, fluidise the mix, remove air bubbles and so form a homogenous mass. The author also discusses detailed aspects of using vibration equipment and correct site practice to achieve good quality concrete. /TRRL/
