• Abstract:
  The service life of prestressed concrete piles is, in part, dictated by the time required to corrode the steel once ; chloride ions are at the surface of the steel. Stainless steel materials, although limited in availability in strand ; form, have a higher tolerance to chloride ions and hence can provide a means to extend the service life. This ; study scrutinized the corrosion and structural performance of three candidate high strength stainless steel ; materials, XM-29, 2205 and 316 with the goal of identifying a possible solution that uses stainless steel for ; prestressed concrete piles. ; Laboratory studies were conducted to characterize mechanical and stress-corrosion resistance of the different ; materials. Subsequently, four, 14 in square, 75 ft long prestresed instrumented piles were fabricated at a ; commercial prestressing facility for future testing by FDOT. Three of the piles were made using the three ; different stainless steels evaluated; the fourth was made using a low relaxation carbon steel as a control. The ; study showed that it was feasible to use all three stainless steel materials for prestressing piles but 2205 was ; most suited for this application.
