With regard to the PN-EN 206-1 standard, the individual corrosive components
of water affecting concrete, criteria for evaluation of chemical corrosiveness of groundwater
and class of exposure were presented. The variability of particular corrosive components
was explained with the use of an example of Quaternary groundwater of the Warsaw agglomeration.
Those chemical components of groundwater which have statistically dominant
infl uence in evaluation of corrosive impact on concrete were indicated.
