Consolidation of Concrete By Internal Vibration

When moving concrete with the vibrator, the concrete will segregate; the lighter materials move (basically water) while the heavier materials (cement and aggregates) stay where the concrete was deposited. 3. The vibrator needs to be inserted into the previous layer about six inches.Онлайн-запрос

What You Should Know About Vibration| Concrete

In internal vibration, the vibrator is immersed in the interior of the concrete and the vibratory waves carry outward to the surfaces. In external vibration, the vibration is applied to the surfaces and the vibratory waves penetrate the interior. On any construction job the vibrators should match reasonably well the concrete mix being vibrated.
