A concrete vibrator shaft is a part of a concrete vibrating tool that connects to a concrete vibrator head and transmits power from a motor. A variety of shafts and heads can replace worn components, modify tool function or adapt a concrete vibrator for specific applications.
A vibrating concrete tool is used to remove trapped air bubbles that can weaken a concrete structure or create honeycombing when the aggregate is not fully consolidated. This will allow the rebar inside of a concrete slab to bond and strengthen the structure.
There are many different types of concrete vibrators to choose from, including gas and electric. Both have their advantages and disadvantages.
Gas powered concrete vibrators are portable and offer a more comfortable working environment as they do not drag an electrical cord through wet concrete, but they are less powerful than electric concrete vibrators.
Electric concrete vibrators are more popular and have the advantage of being able to use longer whips to thoroughly remove air pockets that can be difficult to reach with gas vibrators.
The amplitude of the vibrations is what determines the effectiveness of the compaction. The higher the amplitude, the more complete and effective the compaction.
This is also where the difference between an electric high frequency and a flex-shaft vibrator comes into play. An electric high frequency vibrator has a frequency converter built into it that converts single phase power into three phase which results in a more stable amplitude. This means that the electric high frequency vibrator can compact at almost twice the rate of a flex-shaft vibrator, which is great news for those looking to get the most out of their tools!
