Abstract: In recent years, several fiber reinforced composites have been successfully used as prestressing materials for demonstration highway structures. Since these materials are relatively brittle and are subjected to high permanent stresses due to prestressing, their durability and ductility in an alkaline concrete environment is of utmost concern. This paper reviews results from recently completed tests to assess the suitability of advanced composites as pretensioning materials.
