Tag: Test method Test method with electrolyte solution representative of actual service DIBt test

Various failures of prestressed concrete structures caused by hydrogen-induced stress corrosion cracking at the beginning of the 1980s led to the development of a constant load test based on laboratory as well as on-site investigations.20,60 In  this test, the prestressing steel specimens as delivered were stressed in a stressing frame under constant strain to 0.8 Rm, at 50ëC. Based on the

The demand for a test to assess the susceptibility of prestressing steels to stress corrosion cracking dates back to when prestressing steels were introduced. Federation International de la Precontrainte published the first reports,58,59 which described the evaluation of SCC for various prestressing steels. The data were obtained from research and round-robin tests with different electrolyte solutions that did not necessarily
