In order to prevent tendon from corrosion and to provide a sufficient bond between tendon and concrete, post-tensioning grout has been used. But, the normal mixture with w/c ratio of 0.40 and add the expansive agent for 1% was not support for specification(BS EN 445) compliance. Thus, it should add some supplementary cementitious materials to improve the properties. Therefore, based on this test result, not only evaluation of bleeding, volume change, fluidity, and compressive strength, but also estimation of the shrinkage of post-tensioning grout under restrained condition remains as a pressing need.
