Popis: Investigation of biological corrosion of concrete requires that composition of material, surface and aggressive environment have to be taken into account. Sulphate resisting cement, as one of the resistivity improving factors, was used for preparation of concrete samples studied in this experiment. Dependences of leached-out quantities of selected ions regarding bacterial versus non-bacterial environments were investigated and evaluated using correlation analysis. Leaching trends of calcium, silicon and aluminium strongly depends on the aggressiveness of medium which are the samples exposed to. A weak correlation was found for the leaching trends of aluminium and iron in both bacterial and non-bacterial media.
