Defining patterns in the influence exerted by the interelated biochemical corrosion on concrete building structures under the conditions of a chemical enterprise

The effect of microbial and chemical corrosion on concrete structures operated in the conditions enterprises has been established that makes it possible to reliably predict timing their decommissioning order prevent industrial disasters. Even though construction complies with all building codes, eventually undergo biological corrosion. innovation proposed this study implies investigating depth degree damage at microscopic level by method raster electron microscopy. In addition, TPD-MS suggested for determining quantitative qualitative state carbonate components sulfur compounds. This found samples from titanium dioxide production plant, amount carbon release is twice less than control t=600 °C while dioxide, contrary, increases. due ability thionic bacteria accumulate sulfate acid destroys cementing component concrete. reported results confirm impact products activity Acidithiobacillus thiooxidans microorganisms processes when using method, was storage room finished product heating sample leads a significant СО2 t=580–600 °C. However, experimental are almost lacking compounds because metabolites microfungi interfere its formation. Microscopic REM studies revealed localization Aspergillus fumigatus patterns related mechanism forms metabolism
