What is it about?
The topic of paper is bond and re-anchoring of post tensioned tendon in case of strand failure inside cement grouting with voids. In the study the a set of tests were conducted to find how does the incomplete grouting affect on bond and re-anchoring of steel tendon. In this paper it is shown that failed tendons can re-anchor within limited length in incomplete grout.

Why is it important?
Grouted tendons are commonly used in construction of bridges and other structures. The quality of grouting is essential to provide the durability and robustness of the structure. A defetive grout can make tendon strands prone to corrosion and failure. In this paper, the bond and re-anchoring of post-tensioned tendons in grout in case of tendon failure is assessed. A limited re-anchoring length of tendon in incomplete grout increases the robustness of the structure, as the broken tendon can maintain its effectiveness outside of the failure region.
