✦ Synopsis

The simultaneous action of corrosive media and mechanical stresses on concrete leads to stress corrosion cracking phenomena. The flexural strength of mortar specimens in sulfate-solutions has been found to depend significantly on the external load being applied during the sulfatesolution exposure of the specimens. Low stresses cause a relatively higher specific decrease of flexural strength than higher stresses. The effects observed are of fundamental importance with respect to the evaluation of the durability of concrete structures subjected to corrosive media.
