Abstract:
A coating material for a tendon for prestressed concrete includes a curing composition, the curing time of which is so controlled that the composition is held in an uncured fluid state for a predetermined time after the concrete hardens. After the predetermined time passes, the composition cures. By coating a tendon for prestressed concrete with the coating material having such properties, an antirust effect of the tendon, an improved adhering force of the tendon to the concrete and a decreased cost of manufacturing prestressed concrete can be obtained.
