Tartalmi leírás:
Biodeterioration can be seen as a process, which decreases value of materials and constructions and has been defined as the deterioration of materials of economic importance by organisms. Since the discovery bacterial genus
Acidithiobacillus
caused rapid corrosion of concrete especially
Acidithiobacillus thiooxidans
.This paper presents the results of concrete specimens’ biodeterioration study by bacteria
Acidithiobacillus thiooxidans
and
Desulfovibrio
genera under model conditions. Biodeterioration was carried out in laboratory reactor, where simultaneous effect of
Acidithiobacillus thiooxidans
and
Desulfovibrio
genera happened. The pH values of leachate, mass of concrete specimens change, Ca and Fe content in leachate were evaluated. After experiment the morphology of corroded surface were observed by scanning electron microscopy.
