Best 14+ Guideline for Use of Concrete Vibrators | What is Concrete Vibrator?

The use of Concrete Vibrators is most important in a construction project is you do not use or didn’t have proper knowledge then you may face honeycombs in concrete.

Indirectly money lost or you are site engineers then you lost your job due to mistake so read this The Civil Experiences article carefully and follow us for more learning.

What is Concrete Vibrator

concrete vibrator is a mechanical machine that can be run on a battery or some heavy use a steady power which is used for a construction project to improve the structure of concrete and durability by settling your concrete ingredient

Why use a concrete vibrator?

Long term durability is a key aim to use concrete vibrators

During the pouring of concrete air bubbles creates in a wet green concrete mixture and form cavities or honeycombs in concrete which greatly reduce the strength and durability of the structure

Vibrators impact air bubbles and remove them from the mixture and make create final concrete compacted free from voids which have high life spam compared to non compacted concrete

Guideline for use of concrete vibrators

Concrete vibrating equipment use is best for any building construction works line beam, columns, slabs for any other construction work

But if you have no enough technical knowledge to use of concrete vibrating tool then it also creates major issues for concrete also in structure

Like unskill labour usually want to use concrete vibrating equipment more so that they have less physical work but stop them to do and provide proper guidelines for a concrete vibrating tool which you learn here with Civil Experience

  • First of all, Keep in your mind that Vibrators are not tools for spreading concrete in formwork because it may be turn result in the segregation of course aggregate
  • The part of vibrators should not contact with an object like hardened concrete, steel reinforcement, formwork no matter wooden or ms steel because it may lead to (impact) damage to the bearing
  • For achieving the best result, compaction of concrete should be of stiffest enough as possible consistency preferably, w/c ration of about 0.3 to 0.35
  • If immersion vibrators use to compact concrete then the thickness of the layers places should not be more then than the depth of the operating part of the vibrator by more than 25 percent
  • Depending upon the work of nature of works vibrators use at horizontal, vertical or incline angles but if you should use a needle vibrator for compaction of concrete vertically and should be immersed in beams and columns or any other thick part of the building at regular intervals
  • Generally, an Electric concrete vibrator job completes the desired result in 5 to 15 seconds at a point of 45 cm to 75 cm, instead of for longer periods at wider intervals
  • To insure through the union of layers, the needle vibrator for compaction of concrete must be penetrated to the below layer of new layer for several inches so that you gain better results in finished concrete work
  • The form vibrator for concrete should be Definitely secure to the form as otherwise its efficiency is greatly reduced. The duration of form vibration varies between 60 to 90 seconds
  • Excess use of vibration of concrete mix with the slump of higher than 100 mm may produce segregation of concrete, Delay in the formation of the surface. The vibration of concrete for more than 3 minutes is only a waste of effort and time without any harm to the concrete
  • A concrete vibrator may decrease the entrained air in the air-entrained concrete to 50 percent so air-entrainment should be twice if the concrete mix is to be vibrated
  • Surface vibrator used for compaction of concrete in straight continuous strokes of 100 mm to 200 mm overlapping on the previously compacted concrete also keep in mind that vibration duration may approximately vary between 30 to 60 seconds
  • The surface vibrator for the concrete vibrator must be kept far away about 10 to 20 cm from the formwork
  • The surface vibrator for concrete must be withdrawn by an upward jerk and it should not pull slowly on the placed concrete
  • After completion of vibration work at one place then slowly remove the vibrator vertically after turning off the concrete vibrator motor
