Abstract
Corrosion of prestressing steel may lead to sudden, so called brittle failure, due to the special microstructure of the steel and the high tensile forces. Such brittle failure may seriously reduce the load capacity of a prestressed concrete structure. In principle all stressed high strength steel is sensitive to this process. This paper focuses on bonded post-tensioned steel, where the steel is surrounded by metal ducts, injected with cementitious grout. One of the factors involved is incomplete filling of the ducts
