Abstract:
This specification covers uncoated high-strength steel bars intended for use in pretensioned and post-tensioned prestressed concrete construction or in prestressed ground anchors. Two types of bars are considered: Type I bar, which has a plain surface and Type II bar, which has surface deformations. The bars shall be rolled from properly identified heats of ingot cast or strand cast steel. The bars shall be subjected to cold-stressing and then shall be stress-relieved to produce the prescribed mechanical properties. Yield strength, elongation, and tension tests shall be performed.
