| Description | The paper is focused mainly on sulphate attack. Concrete samples from the Charles Bridge in Prague were examined. A succession of degrading mineral formation was suggested. Variations of efflorescence assemblages were monitored for ten years. Microscope methods represent a relatively new approach to solving the deterioration problems. They enable evaluation of the state of concrete constructions and in cooperation with hydro-geochemistry, mathematics and statistics permit prediction of the durability of a structure. |
