In this study, experiments on shrinkage and expansion behaviors of high-strength concrete containing reactive aggregate were carried out. The strain distribution in the cross section was examined, and the effects of seal curing, cross sectional size, environmental conditions up to 14 days and dry-wet repetition on the shrinkage and expansion behaviors were investigated. The results proved in the case of high-strength concrete that the expansion caused by alkali-silica reaction started from outer layer under the condition of 40_??_ and of 97.5%R.H.. Further, it was found that the expansion caused by alkali-silica reaction came about at a small value of strain affected by autogeneous shrinkage.
