Many building materials lose their original properties due to the impact of the aggressive environment on them. These can be temperature changes, contact with water, salt or carbon dioxide. The consequence of these influences is often the appearance on the surface of corrosion materials. As practice shows, corrosion processes do not bypass the concrete structure, including concrete floors. Of course, the surfaces created from such material require a certain protection so that corrosion does not destroy their structure, but the processing method must be selected correctly. The choice of concrete protection technology is often affected by the causes of the occurrence and spread of this negative phenomenon, as well as the type of corrosion.
So, what is the main reason that corrosion appears on the surface of the concrete floor? Creating a floor of concrete, it is important to understand that this material most often has a mineral base and a capillary-porous structure, which is a prerequisite for the spread of corrosion on its surface. This is explained quite simply – due to the effects of atmospheric factors in the pores of concrete, crystals are formed, which with abundant quantities can create cracks. In most cases, building structures and materials also suffer from chlorides, carbonates and sulfates that dissolve in the air and fall on a one or another surface.
Concrete protection is a very complex and complex process, but, as mentioned earlier, to achieve the maximum result, it is important to accurately determine not only the cause of corrosion, but also its variety. To date, when classifying corrosion, experts are guided by one criterion – and this is the degree of deterioration in corrosion properties and characteristics. Accordingly, there is the first degree of development of corrosion when the components of concrete are washed out; The second degree implies the formation of corrosion manifestations without the so -called astringent characteristics; The third degree is the accumulation of crystallizing type salts, which do not dissolve and as a result increase their volume.
After clarifying all the important points regarding corrosion processes and the degree of their distribution, it is necessary to decide on the methods of protecting concrete structures and structures. Professionals in this matter recommend using the protection of primary and secondary type. Primary protection should be understood as the use of special modifying additives for these purposes, which in turn are divided into plasticizing, water retaining, stabilizing. In addition, there are additives that regulate the degree of grasping of concrete mixtures used and their porosity. If we talk about the secondary protection of concrete, then, as a rule, this is the use of biocide materials that fight fungal formations, glogue coatings (polyethylene film, oil cells, polyisobilen plates), sealing impregnations (epoxy-polyurethane or polyurethane compound), acrylic and lacoma coatings (liquid plastic, polyurethane enamel, etc.), paintwork mastic coatings. Quite often, concrete floors and other surfaces from this material are not processed manually, but with the help of special equipment, and it can be grout machines, grinding equipment, automatic washing machines that are supplemented with special brushes, and others.
