Curable composition for tendon for prestressed concrete and tendon

摘要

A curable composition for application on the surface of a tendon for prestressed concrete contains at least one epoxy resin and at least one moisture-curing type curing agent. In the curable composition, the tensioning-permitting time L at 90 DEG C is at least 20 hours, and the number of days M required to cure at normal temperature is at most 1095 days. The curable composition permits complete prevention of corrosion without relying on injection of a grout into a sheath and can be used even when the curable composition is heated to a high temperature such as is generated upon hardening of concrete. <IMAGE>
