Concrete vibration

The concrete vibration is a crucial step in the construction of any concrete work. It ensures the quality, durability and strength of the structure by removing the trapped air bubbles and ensuring homogeneous distribution of the material. To achieve these objectives, it is essential to have adequate vibration equipment and equipment. In this article, we will explore in detail the various types of concrete vibration equipment available on the market and discuss their importance to achieve optimal results.

Internal vibrators

Internal vibrators, also known as immersion vibrators, are one of the most commonly used types of concrete vibration equipment. They are composed of a vibrating head and an electric or pneumatic motor that generates vibrations. These vibrators are inserted directly into the fresh concrete, allowing the material to be compacted by removing the voids.

There are different sizes and shapes of vibrating heads to adapt to different applications, such as slabs, posts, walls, etc. In addition, internal vibrators can be used manually or mounted on machines to facilitate work on large surfaces. Their versatility and efficiency make it one of the most essential tools to ensure a good concrete vibration.

External vibrators

External vibrators, also known as surface vibrators, are another type of vibration equipment of the widely used concrete. Unlike internal vibrators, external vibrators are placed on the surface of the concrete and generate vibrations that spread through the material.

These vibrators are particularly suitable for applications where access is limited or where extended areas need to be drained. They are commonly used for concrete slabs, roads, bridges and horizontal surfaces. External vibrators are usually powered by electric or hydraulic motors and are equipped with vibrating plates or rollers to create vibrations necessary for the consolidation of concrete.

High frequency surface vibrators

High frequency surface vibrators are a specialized type of external vibrators that are distinguished by their high vibration frequency. These vibrators are designed to work at frequencies of up to 10,000 laps per minute, allowing for better concrete consolidation in a shorter time.

High frequency surface vibrators are particularly useful for concrete with low water content and high plasticity, where effective consolidation can be more difficult to achieve. They are also effective for applications requiring smooth and uniform finish, such as industrial floors and architectural surfaces.

Vibrating tables

Vibrating tables are another vibration equipment of the commonly used concrete, especially for prefabricated concrete elements. They consist of a vibrating horizontal table on which moulds or prefabricated elements are placed before being filled with concrete.

Vibrating tables use low frequency vibrations to compact and consolidate concrete in mussels. They are generally equipped with electric or hydraulic motors and can be programmed to adjust the frequency and intensity of vibrations according to the specific needs of the material.

Concrete vibration equipment: The key to the quality of your work

The use of good concrete vibration equipment is essential to ensure the quality and durability of concrete works. Whether with internal vibrators, external vibrators, high frequency surface vibrators or vibrating tables, each type of equipment plays a specific role in the consolidation and homogeneous distribution of concrete.

When choosing your vibration equipment, take into account the size of your project, concrete specifications and access constraints. Investing in quality vibration equipment will allow you to achieve optimal results, improve the strength and durability of your concrete works, and ensure the satisfaction of your customers.
