Light concrete – Porous artificial aggregates are used to make lightweight concretes (expanded clay, glinoporyt, metallurgical pumice stone, granulated slag). The type of aggregate is largely determined by the location of the plant. Expanded clay is most often used. Blast and Portland cement are used as a binder.
Division …
Artificial aggregates are obtained from heat-treated rocks and industrial waste. The use of a specific type of artificial aggregate depends to a large extent on their production in a given region of the country.
Criteria for the division of artificial aggregates:
1. Due to the type of rock raw material …

High pressure spraying of material under pressure (the so-called. combined shower):
With combined high-pressure spraying, the material is compressed to pressure by a pneumatic piston pump 40-50 bars and pressed into the gun. The material is coarsely atomized as a result of the pressure drop after exiting the spray nozzle, after which …
Painting spray interiors.
Currently, electromagnetic spray guns are used for spray painting, in which the paint is pumped into the spray nozzle under the influence of vibrations of the metal diaphragm. According to the power of the gun, paints of different densities are used. It is generally defined as, …
