| Outline of Final Research Achievements |
In general, as for test of drying shrinkage of concrete, 100 by 100 by 400mm prism specimen is used, and test period is more than 180 days. In this study, the method to estimate a drying shrinkage value measured using a 100 by 100 by 400mm prism test specimens at the 182 days in the period when it had a short. Various kinds of concrete made in laboratory or in ready mixed concrete factory are used in this study. As a result, it is shown that the drying shrinkage strain measured by core test specimen of φ50 by 100mm at 42 days was equivalent the drying shrinkage strain measured by prism specimen of 100 by 100 by 400mm at 182days.
