The basic principal of concrete vibration is to consolidate the mix by removing entrapped air. Vibration is a series of rapid compressive impulses which greatly reduces the surface friction between the various size particles of the mix. The result is the rearrangement of these particles into a denser mass. During the vibration process. Unwanted trapped air escapes to the surface. A swivel-mounted base and reliable Honda engine make this power source ideal for concrete vibration applications in remote areas. This unit swivels 360° for easy movement around the job site. Additionally, it eliminates the need for a separate generator on site.
