| Research Abstract |
Shrinkage strain of concrete sometimes shows much larger than previous values because of aggregate becoming worse. However, it is difficult to restrain to use this aggregate, because the testing method to measure shrinkage strain has not been established. In this study, a new testing method was proposed. Finally it becomes clear that autogeneous shrinkage strain before 7days age and drying shrinkage strain after 7days age are measured at same testing specimens using proposed testing method
