Vibrator for concrete - application in construction

To date, monolithic construction is gaining increasing popularity, as a result of which specific requirements are imposed on cast concrete structures, their increased strength and uniformity of structure. The most popular and, in turn, modern and easy to use equipment is a vibrator for concrete, with which you can not only increase the amount of concrete, but also get a better solution.

Application

If you do not use any special devices and machines after the solidification of the freshly mixed concrete solution is complete, its strength indices will be far from the maximum parameters.

What causes the violation of the technological process?

The consequence of this is residual water and air bubbles that accumulate in the concrete solution. And when it finally dries, they form a porous structure, as a result of which the resulting structure will have very low strength characteristics. But this can be prevented by using a vibrator for concrete.

In addition, the negative impact on the performance indicators for the strength of the mortar has a violation of the technology of pouring concrete - its uneven distribution. But it is worth noting that it is difficult to notice visually. At strong influence of high-frequency oscillations causing vibration, there is a pushing out of similar impurities from a concrete solution on its surface.

Deep Vibrators

In addition, this method allows you to achieve maximum density and uniformity of the resulting surface from a solution filled in a volume. From this follows the conclusion that vibration treatment can significantly improve the strength and durability of concrete structures. The best result will be achieved if, during operation, the vibrator for concrete is placed in the thickness of the solution.

The special apparatus in its design has three main components: a vibration oscillator, a flexible hose and a vibrating mace that directly transfers vibrations to the concrete solution when immersed in it. One of the main classifications for concrete vibrators is their difference according to the principle of the device's motor operation, which generates oscillations.

Principle of operation

The vibrator for concrete can work by means of compressed air, liquid, electric energy (electric motor) or use fuel in a liquid state. The biggest time of autonomous work is the vibrators with internal combustion engine. However, the greatest popularity due to its high profitability was gained by an electric vibrator for concrete.

Price category

The totality of all technical features and characteristics determines the final cost of one or another type of equipment. They can differ as to the engine power and the frequency of oscillations reproduced by it, and by the use of certain innovations in the design.
