CONCRETE VIBRATOR SET - EY20+F+C+32MM

A concrete vibrator is a concrete tool that produces stronger
 concrete by vigorously shaking the concrete
 right after you pour it to eliminate the air bubbles or air pockets.
 
As wet concrete is poured, air bubbles become 
trapped within the mixture creating cavities or
 honeycomb-like spaces. Left untouched, 
“honeycombing” can compromise the cement's longevity and strength.
 Vibrators force the trapped air out of the mixture leaving
 the final product a more compact and level slabE.

Vibrating concrete is critical because by removing air pockets
 & packing the aggregate particles together,
 it increases the density and strength of the concrete. 
Tightly packed particles will result in a stronger,
 more durable concrete structure.
