ANALYSIS OF CORROSION PRODUCTS FROM WW2 CONCRETE BUNKERS IN CZECHIA

The paper deals with analysis of corrosion products from historic concrete bunkers which were built in the 1930’s. Most of these objects evince numerous failures due to water penetration into the concrete structures. Two heavy bunkers became the target of research which was focused on chemical and biological analysis of corrosion products from concrete structures. The results showed that concrete used for two analyzed fortifications successfully resisted the long-lasting effects of chemical corrosion as well as bio-corrosion (this corrosion causes only aesthetic defects)
