The problem of corrosion destruction of building structures, despite the existing scientific and engineering achievements in this area, does not lose its relevance. The purpose of the study is to determine the degree of impact of various types of microorganisms on the physical and mechanical properties of concrete. We carry out the assessment of the possibility of concrete to serve as a substrate for various types of biodestructors by determining the moisture absorption and pH of the extract of the concrete samples. As a result, we experimentally determine the mechanism of action of various microorganisms on concrete. Also we define the taxonomic composition of the most aggressive microorganisms for concrete. During the study we assess the effect of biofouling on the physical and mechanical properties of concrete. The results of the study serve as a basis for the selection of the most effective corrosion protection methods for concrete structures operated in biologically aggressive environments.
