Title: CPN 33 - Compaction of Concrete Using Immersion and Surface Vibrators
Appears on pages(s):
Abstract:Concrete is compacted for two main reasons:
■ To remove any voids in the concrete and to obtain the maximum strength and density of the concrete in place.
■ To obtain complete contact between the concrete with the formwork and the surface of the reinforcing steel.
It is generally accepted that 5% voids in the concrete can lower the concrete strength by as much as 30%.
