To obtain a cellular foam concrete, two main methods are used: the production of foam concrete using a steam generator installation and barototechnology. Basically, these two methods suggest the use of the same components and the same amount of raw materials, but the order of adding them to the main composition and the closing method differ. It is these technological differences that determine the different quality of the received foam concrete. Let us consider in more detail what one and other technology is and what advantages and disadvantages are characterized.

Obtaining a foam concrete on barotics is considered a mild and simple way, requiring less expenses and less time to produce a finished product. All components that are part of the manufactured foam concrete are placed in a special mixer, which should be sealed. These are sand, foaming components, water, hardening accelerators. With the help of high pressure, a certain amount of air is pumped into this mixer, and in the process all components are well mixed. If the composition of the foam concrete is still filled with aeronautics additives, then the solution is more air. After mixing, the solution enters the pipeline, and is poured from it by special forms. Only at the last stage in cast forms does the solution cease to be under high pressure, and the volume of the mixture increases significantly.
Barotechnology is used as a more economically and economically profitable way to obtain foam concrete. The low cost determines the use of inexpensive equipment, and the production process itself can be organized anywhere. In addition, the manufacturing process in this way takes less time than the technology for the production of foam concrete using a steam generator.
But for all these advantages, barotics has a number of disadvantages. The composition needs to introduce more water so that the whipping process is more effective. The manufacture of foam concrete in barotics gives a large-porous structure with large voids (more than 2 millimeters). This reduces the strength of foam blocks, which is why the bearing capacity of the walls decreases.

The use of powerful steam generators requires absolutely accurate observance of proportions when mixing the main components of the solution. Cement and sand are poured into the mixer with special dispensers, and sometimes the ash of the monos is added instead of sand. The zola of the healing helps to reduce thermal conductivity, due to which heat conservation increases. After mixing the bulk components, water with additives dissolved in it is introduced into the mixer. As a result of mixing, an absolutely uniform composition resembles ordinary concrete should be obtained. Next, using a steam generator installation, foam is added to the finished solution. The number of foam depends on what density foam concrete should be obtained. The steam generator production of foam concrete, the video of the process can be found on the Internet, allows you to get better raw materials for construction. Accordingly, the costs of such a production process will be much higher than the costs of barotics. This also affects the final cost of finished products.
Foam concrete, obtained in the process of production with a steam generator, is characterized by a more correct and high -quality structure in which there are no large air por. This explains the high strength of the material.
Thus, two considered technologies for the manufacture of foam concrete have supporters and opponents. Those who are more interested in quality choose foam concrete, made using steam generator technology. Those who set themselves the goal of saving can buy a cheaper and less high -quality foam concrete received by barotics.
Any foam concrete technology should provide the possibility of safe transportation of finished raw materials over long distances. In this case, the integrity of the structure should be preserved. Foam concrete should differ in resistance to possible shrinkage, stratification. In construction, foam concrete with a small porous structure is considered more valuable and reliable. It provides higher stability of buildings by increasing the strength of the supporting structures.
