The strength of the building and its individual concrete structures and ceilings, both with monolithic construction and in collecting construction from finished concrete and reinforced concrete structures, directly depends on the quality of the concrete mixture used and its filling. The strength characteristics of the mixture are determined by the quality of the component fillers used and their ratio, as well as taking into account the temperature and humidity characteristic of a particular area, and the conditions in which the concrete mass will freeze.
As for styling, here the monolithic of the fill and the absence of cavities are crucial. When pouring, even if you produce it with a small stream, voids inevitably occur due to air and uneven distribution of the mixture. If voids occur near the reinforcement, its corrosion will begin over time, which will lead to a loss of strength of the concrete structure and its gradual destruction. Also, the micro-floods formed when pouring air are leading to the destruction of concrete under the influence of seasonal temperature fluctuations, and uneven shrinkage can cause cracks in the formation of cracks-all this reduces the strength and durability of the concrete parts of the building and can lead to deformation of the building as a whole.
In modern construction, when pouring concrete mass, special tools are used — deep vibrators. The deepest concrete vibrator is designed to compact concrete mass during pouring, as well as to ensure its uniform distribution and elimination of air cavities. The principle of operation of this device is that when the vibro -boula is immersed in the concrete mass, it transfers mechanical vibrations to this mass, thereby compassing it and releasing the air that enters the mixture during filling, and, thus, providing excellent adhesion with reinforcement. Depending on the volume of the constructed structure as well as on the distance between the segments of the reinforcement, vibro -boulaws of various diameters are used. In addition, devices differ in indicators such as the frequency and amplitude of the oscillations. The choice of these parameters depends on the size of the mixture fractions. For example, for concrete mass of a large fraction, it is recommended to use the tool with the maximum amplitude of the oscillations and their lowest frequency, which will provide the most uniform distribution of mass throughout the shape of the structure.
The use of devices such as the deep vibrator for concrete 19 can significantly reduce the time of erection of reinforced concrete structures and significantly facilitates the work of builders, ensuring the rapid and efficient laying of concrete mass with filling all possible voids and uniform coating of reinforcement.
