How to use the concrete vibrator

The immersion vibrator drives trapped air out of fresh concrete so it ends up dense, with no honeycombing. Under-vibrate and you leave voids; over-vibrate and the aggregate sinks while the paste rises.

01
Pick the unit and the head
No power or a big site → gasoline (SQ28 PRO) or backpack (SQMG28); indoors or noise limits → electric (SQVEH40 or the mini vibrator). Small head for thin or heavily reinforced elements; 38 mm for slabs, beams and footings.
02
Pour and vibrate in lifts
Place concrete in even lifts and vibrate each one before the next. Fill a tall wall or column in one go and the air at the bottom can't get out.
03
Insert vertical and fast
Drop the head in vertically and fast, going a little into the lift below while it's still fresh: that knits both lifts into one piece.
04
Hold 5–15 seconds per point
Vibrate until a thin layer of paste rises and large bubbles stop. Longer doesn't help: it segregates the aggregate.
05
Withdraw slowly
Pull the head out slowly so the hole closes itself. Yank it and you leave an air channel inside.
06
Even, close spacing
Repeat on an even grid, spacing points ~1.5× the action radius so the circles overlap. If no paste shows between two points, move them closer.

Do this

Always insert vertically, on systematic, evenly spaced points.
When shiny paste rises and bubbles stop → withdraw and move to the next point.
On walls and columns, vibrate lift by lift as you pour.
Wash the head and hose when you finish.

Avoid this

Don't drag concrete with the head: you segregate the aggregate.
Don't over-vibrate: water and paste rise, aggregate sinks.
Don't hold the head against the formwork or rest it on the rebar: it marks the exposed face and loosens the steel.
Don't yank the head out: it leaves an air channel.

Safety

Rubber gloves and boots; you're in fresh concrete.
Mind the cable (electric) or hot exhaust (gasoline).
Don't force the hose into sharp bends.

Parts of a concrete vibrator: motor, coupling, hose and head

Every concrete vibrator has a motor, a coupling, a hose with a flexible shaft inside and a head that does the vibrating. What each part does, which ones wear and how to look after them so it doesn't lose power.

Why does concrete honeycomb, and how do you vibrate to prevent it?

Honeycombs are trapped air and poorly consolidated mix. Why they appear, the vibrating technique that prevents them (vertical, 5–15 s, overlapping points) and which SIMAQ vibrator fits each element.
