The term concrete refers to artificial stone, a building material obtained by molding and solidifying a multicomponent mixture. In the classic version, it consists of:
· (cement);
· (sand, gravel);
· water.
If necessary, additional additives are added to the product, increasing the frost resistance of the mixture, increasing its plasticity, etc.
What are the advantages of concrete? Firstly, we are talking about the impressive technical characteristics of the material – its high mechanical strength, resistance to aggressive environments, and durability. Secondly, monolithic construction technology is optimally suited for making complex engineering solutions a reality. The main thing is to decide on the choice of formwork – a structure into which a cement–sand-crushed stone mixture is poured. In order for the composition to acquire its design strength during hardening, a deep vibrator for concrete is used. This is the name of the equipment that seals the multicomponent mixture during its pouring into the formwork. The components of the technical equipment are: a mace (vibrating tip), an electric motor and a flexible shaft.
How does it all work? The vibrator's power unit is responsible for generating vibrations, and the vibration tip is the pulse source. A flexible shaft with a club is placed inside the working mixture – as a result of the operation of the technical device, excess air and moisture residues are removed from the concrete, which makes it much stronger.
What kind of equipment is used in practice? Classic-style deep vibrators are in high demand. During operation, their tip vibrates at a frequency of 12,000-20,000 vibrations per minute. The flexible shaft transmits rotation to the vibration tip from the power unit by means of an eccentric.
Portable deep vibrators are found at many facilities. They differ from the devices described above in more modest dimensions and power. They are equipped with collector type electric drives. According to experts, the price-quality ratio of these devices is optimal.
High-frequency deep vibrators have maximum performance. They have a different vibration method than in the installations described above. The electric drive of such equipment is directly a vibrating tip. The vibrators are powered by a current with a frequency of 200 Hz.
