Abstract
The article points out the lack of radically effective worldwide methods of anti-biocorrosion protection. The author considers the role of microorganisms on concrete corrosion, describes the mechanisms of biological effect and biofilm formation on concrete surface. The article focuses on the determination of causes and peculiarities of cement concrete biocorrosion in conditions of high humidity. According to the author, biocorrosive impact reduces strength characteristics of concrete and causes its fast destruction. The author has revealed changes in structural-phase composition of concrete during surface biofouling. Although there are available methods to increase the bio-resistance of cement-based concretes, it is problematic to guarantee their preservation because bio-destructors have the ability to adapt to the work environment. The paper attempts to assess and predict the resistance of a building material in a biologically aggressive environment properly
