Abstract: Concrete structures severely deteriorated by alkali silica reaction(ASR), which has reduction of strength in internal concrete and occurrence of yield and/or rupture of steel bar due to excessive ASR expansion,have been reported in 2003. In this study, unreinforced concrete prism (10x10x40cm), reinforced concrete prism (10x10x40cm), reinforced beam (10x20x100cm) and reinforced cubic specimen (40x40x40cm) were made. And the expansion of specimens and strain of steel bars occurred by ASR expansion in the reinforced concrete was measured. As the results,it was recognized that as teel bar yielded by the ASR expansion force in reinforced concrete. In reinforced concrete beams, cracking could not be seen near steel bar. In reinforced concrete cubic specimen containing large amount of pores ,th e expansive coefficient became small values.
