To create concrete of good quality and the desired homogeneous structure, special tools and various devices are used. For example, there are internal vibrators that are used to compact solid concrete structures or reinforced concrete products for prefabricated construction. This installation is very useful when creating foundations, floors, and concrete floors.

Such equipment improves the properties of the concrete mixture by removing excess air remaining after mixing the ingredients, simplifies the process of producing structures, and also reduces costs and construction time. Types of vibrators may differ in design and application, but the principle of operation is the same for all.

Pros and cons of using

When working with a vibrator, the following advantages are distinguished:

• durability of a single base, in the installation of which a concrete vibrator is used;
• no manual work required, the process is automated, which reduces labor costs;
• when working with vibrators, the time for work processes associated with concrete is reduced;
• the construction of structures is accelerated, since compaction with a vibrator increases the solidification rate;
• the seal can be transported without problems;
• the range of products differs in quality and price category;
• the sealing mechanism for removing air bubbles in concrete does not create much noise and creates comfortable use;
• a manual mechanism for compacting the solution requires a workforce of one person;
• hand-made is possible;
• 220 volt concrete vibrator increases adhesion between concrete mortar and reinforcement, which improves the strength characteristics of the structure.

The 220 V concrete vibrator has the following disadvantages:

• high cost;
• poor protection against possible mechanical damage;
• electricity costs.

Purpose

The prepared concrete solution, despite thorough mixing, remains heterogeneous, which reduces the characteristics of the monolith. In addition to cement laitance, crushed stone and sand, it contains water and air bubbles.

If concrete is simply poured into the formwork, the result will be a structure that is heterogeneous in structure. The use of a vibration compactor for concrete increases the fluidity of the mixture without additional additives, due to the movement of its components. Air inclusions are pushed onto the surface of the monolith, and the fillers are evenly distributed throughout the volume.

After vibration compaction, the volume of concrete poured into the formwork is reduced by 30%. This effect occurs due to getting rid of air-filled voids and more dense packing of sand and crushed stone. As a result, the strength of the massive structure reaches its maximum value and high density for a given grade of concrete.

Operating principle

A concrete vibrator has the following principle of operation: a vibrating tip is immersed in the mixture, which transmits vibration through the nearby layers of the solution. This helps to reduce viscosity and acquire heavy liquid. The process of filling the mixture under the influence of gravitational forces occurs. The result is a dense mixture with a homogeneous structure and no air bubbles. The compacted solution acquires high strength and quality, which increase the service life of the structure being built using a concrete mixture.

Signs of sufficient compaction of the concrete mass

One of the signs is the absence of bubbles in the concrete mixture.
Compaction work with concrete can be carried out in two ways: manually and mechanically. However, it is difficult to achieve good results with manual compaction. Vibration is also not always possible to obtain the required homogeneity. On the one hand, the mixture may not be completely compacted, and on the other hand, it may delaminate due to excessive vibration.

The degree of compaction can be correctly determined using several parameters:

• there is no settling of liquid conglomerate;
• laitance with sand floats to the surface;
• there are no air bubbles;
• After removing the vibrator nozzle, the surface of the conglomerate quickly closes.

Types of vibrators for concrete

There are different types of vibrator for concrete:

• Surface, which is used for floor slabs, screed pouring and for large working surface areas.
• Construction, used in the process of erecting heavy structures. When constructing private houses, they are used to construct foundations and monolithic walls.
• The electric compactor operates from a two-phase network and single-phase 220 V. A 220 V electric vibrator is more often used in the construction of private buildings. The most common compactors are electric deep ones, which are required for particularly important purposes, namely when pouring a foundation.

The 220 V concrete vibrator is different:

• vibration characteristics (low-frequency, medium- and high-frequency vibrations);
• influence on the solution, namely internal and external;
• types of engine.

Seals according to engine type are divided into:

• hydraulic;
• motor;
• electromagnetic;
• pneumatic;
• electromechanical.

Surface (area) models

This type is less common, but it can also be used in private housing construction, and in particular for the construction of baths. When constructing small structures, foundations are rarely very deep, often have a medium or shallow depth, so the use of surface concrete vibrators will also compact the solution well. In addition, it can then be used when pouring floor screed.

The selection parameters are the same - amplitude and frequency of oscillation, number of hours before failure, range of action. The vibrator motor itself is installed on the platform and tightened with bolts.

One of the options for a surface concrete vibrator

When working, it is important to tighten the bolts at the attachment points of the working platform. This will ensure better transmission of vibrations and will also prevent the motor from jumping off the mount. This must be done regularly - at least twice in a quarter of an hour.

Before work, the installation must be grounded, then turned on and slowly moved along the plane. To achieve a good effect, the treatment strips should overlap by approximately 10-20 cm.

How to use it correctly?

In pouring concrete screeds, concrete vibrators are increasingly used.
When working with a sealing mechanism, to obtain maximum effect, the subtleties of its application are taken into account. Thus, each type of seal has requirements for its use. Deep equipment consists of a flexible shaft, which is immersed in the solution depending on the length of the shaft. The vibrating tip should not come into contact with the walls of the form and a distance of more than ten centimeters should be maintained from the formwork.

To assemble the vibrator, follow these steps:

• attach the vibrating tip to the flexible shaft;
• connect the opposite end of the part with torque to the engine;
• fill the joints with sealant;
• fix the shafts.

Upon completion of assembly, the equipment is tested for possible damage. If no faults are found, start a test run. Install the equipment on a flat surface and easily hit the formwork, so as to create vibration waves.

When using this sealant, vibration is transmitted to the solution along the surface that touches the equipment body. Before turning on the sealing mechanism, it should be checked for possible damage and the strength of the threaded joints. After this, the tamping equipment is placed on the workplace and secured with bolts. It is important to make grounding for the safe operation of the vibrating mechanism. During the tamping process, the bolts are tightened after five minutes and one hour of using the equipment, then the possibility of the device loosening and the bolts popping out is eliminated.

Tips for choosing

If you are going to buy, rather than construct, a vibrator for concrete with your own hands, then the choice is influenced by the types of work for which it is used - for fine-grained concrete, purchase high-frequency compactors, and for coarse-grained concrete, low-frequency devices are suitable. Also pay attention to the size of the tip. The wide vibrating tip is used to cover large areas.

When choosing equipment, you need to pay attention to the depth of the flexible shaft.

When choosing equipment, they look at the depth of the flexible shaft, which affects the depth of entry into the concrete solution. The length of the flexible shaft depends on the type of construction. The use of an overly long shaft will result in a decrease in effect due to loss of productivity on the way to the concrete solution. A shaft with a short length does not provide the required immersion.

When choosing tamping equipment, pay attention to the diameter, which indicates the possible spanning distance. With a large diameter of the working surface, the vibrator will have to be immersed fewer times. When choosing equipment, take into account the characteristics of the conditions in which it is planned to be used.

The pneumatic vibrator operates under conditions of constant air supply at the required temperature. They are used in industry and in the construction of heavy, large-sized structures. An electric vibrator requires constant access to electrical networks, which creates difficulties during construction. To simplify the working process with an electric vibrator, use equipment compatible with gasoline.

If reinforcement is present in a concrete structure, a surface vibrator is used that does not come into contact with the metal structure. When choosing equipment for compacting concrete mortar, pay attention to the price, which is one of the main indicators of quality. Having the desire to save money and purchase a cheap mechanism, there is a risk of rapid failure of the working equipment.
