- Synopsis
- This paper presents the technical development on practical application of highly durable pretensioned PC beam with epoxy-coated PC strands for salt attach region. Bond performance of the PC beams is verified by the induced concrete stress at the transfer length just after prestressing. Also, bending tests for the PC beams with epoxy-coated PC strands and normal PC strands are presented and the results conclude that both beams have the same load carrying capacity.
