BIODEGRADATION OF HYDROTECHNICAL CONCRETE
Abstract and keywords
Abstract (English):
It is increasingly important to solve problems of increasing resistance of concrete to biologically aggressive media, since the species diversity of biodestructors is growing steadily. To develop new effective methods of concrete bioprotection, it is necessary to conduct complex research of corrosion processes in biologically aggressive media. The paper pre-sents a modern view on mechanisms of concrete destruction as a result of corrosion. The study determined the depend-ence of biological damage on the physical and mechanical properties of concrete, on the aggressiveness of biodegraders, as well as a number of factors accompanying this interaction. Cement concrete samples subjected to biofouling were used as objects of study. The study includes the main provisions which can be used to formulate the mathematical theory of biological corrosion. Finally, the study substantiates the condition of generality of the methodological approach to the modeling of mass trans-fer processes at biocorrosion and liquid corrosion of building materials.
