Abstract: 
It is often said that concrete that has suffered from an explosion has internal damage. The damage might affect the strength and durability of concrete. However, only a few researches have been conducted to study the influence of damages on the strength and durability of concrete, because concrete structures damaged in explosions and fire are generally demolished. Hence, this research is aimed at investigating the durability of reinforced concrete members that have suffered hydrogen detonation. In their last study [1], the authors investigated the influence of damage due to C4 explosion on the strength and durability of concrete. The results found in the study revealed that concrete that has suffered detonation exhibits decrease in strength, and increase in moisture sorption and air permeability. In this study, the authors investigated the strength and durability of concrete that has suffered hydrogen explosion in order to replicate the severe accident of Fukushima Nuclear Power Plant. For this purpose, compression, absorption, and bending tests were performed. Furthermore, the damage rate of concrete was quantified via a non destructive test performed using a double-chamber vacuum cell developed by R.J. Torrent. This paper presents the condition assessment of concrete damaged by hydrogen detonation.
