Vibrators are commonly used as a way of compacting concrete on site. In case of vibration, compacting gets effected by reduction in internal friction between various particles of concrete due to oscillation of particles which results in a dense and compact mass of concrete. Vibrations can either be Produced in the interior of the concrete […]

Most internal vibrators are high frequency vibrators designed to operate at 12,000 to 17,000 vibrations per minute (vpm) Amplitudes range from 0.015 to 0.08 inches. Frequency is the number of complete orbits per unit of time. Amplitude is the maximum deviation from the point of rest.
These Concrete Vibrators are designed to consolidate concrete and cement with a range of different sized vibrator heads, flexible shafts with electric and gas power sources to pick from. Northrock's design of concrete poker vibrator heads are available in both rounded steel and …
Consolidating and compacting freshly placed concrete with an internal vibrator is a fairly simple and straightforward process. However, precast concrete manufacturers are continually spending unnecessary amounts of time and money repairing defects often associated with the improper use of internal vibrators.

Types of concrete vibrator. According to the method of transmitting vibration, there are three types: internal vibrator, external vibrator, and surface vibrator: 1. Internal vibrator is also called a plug-in vibrator. When working, the vibrating head is inserted into the concrete, and its vibration wave is directly transmitted to the concrete.

Compared with other plug-in concrete vibrating plate, the pocket-100 vibrating plate is very easy to carry, and can be used in a wide range of small concrete slab construction to improve the efficiency and quality of construction.
The typical vibration frequency of concrete vibrators is approx. 200 Hz. This frequency is required to achieve a sufficient vibration performance with compact construction equipment. The performance efficiency of the concrete vibrator has a great influence on the economic efficiency of the compaction process and the quality of the work results.
Concrete Vibrating Tables Applying proper vibration is the ideal way to prevent common problems found in concrete elements, such as bugholes, honeycombing, and cold joints. Vibratory Tables speed up production and eliminate the safety issues experienced when employees are exposed to the lifting and moving of internal and external vibrators.
External vibrators shall be used to reach the center while the internal vibrator can be used to consolidate the center portion of the concrete mass. Lack of consolidation can cause voids, rock pockets, honeycombing, and poor bonding with the rebar. In extreme cases, improper consolidation can affect the structural integrity of the walls.
