Vibrating machines that are fixed to formwork or casting tables or as vibrating screeds to consolidate wet concrete.Increases compressible strength and bond between concrete and rebar and decreases concrete permeability , Decreases cold joints, honeycombing, excessive entrapped air, and segregation, Causes concrete within a circular field of action to act like a liquid almost said in the definition above that vibrators are used to remove entrained air, but of course some concrete products have air purposely entrained to make them lightweight so I’ll use the terms gross voids and entrapped air pockets.
