Abstract
The durability problems highlight the importance of controlling corrosion in posttentioned concrete. The four key factors of corrosion protection of normal posttentioned tendon are presented before grouting, grouting and after grouted. The duct, the voids in grout, the pitting corrosion in coated strand and the anchorage system must be got more attention, and corrosion mechanism, research field and the measurement method of them are also discussed in the paper.
