Characteristic of Autogeneous Shrinkage of the Dam Concrete that used the Coarse Aggregate of the Full Size

Abstract

In this research, the test for autogeneous shrinkage strain of dam concrete specimens that used the coarse aggregate of the full size was executed, and the characteristic of autogeneous shrinkage of a dam concrete was examined. As a result, it was experimentally confirmed the autogeneous shrinkage strain was generated in a dam concrete that used the coarse aggregate of the full size. In the temperature regulation plan of a concrete gravity dam, it was clarified to have to analyze the temperature stress that considered the autogeneous shrinkage strain. Moreover, the validity of the method of test for autogeneous shrinkage strain about dam concrete specimens that used the coarse aggregate of the full size was confirmed by doing a two-dimensional finite element analysis and a three-dimensional finite element analysis.
