Biodestruction of building materials
The paper presents a consideration of conditions resulting in development of thione, nitrification and other microorganisms at the surface and pore structure of building materials. Results of the microbiological analysis of the damaged building materials functioning in a specific environment characterized by sated moisture, mineral and organic dust and wastes of organic origin are submitted. Chemical destruction processes of structure forming ingredients of concrete are shown. Recommendations are given concerning the use of biocides for prevention of biodestruction processes.
