Porous concrete having continuous void of approximately 20% is one of the attractive cement based material. It has been applied to a drainage pavement and a river revetment, which requires a design based on flexural strength. There is, however, no data to discuss about size effect on flexural strength of porous concrete. This paper presents the size effect on flexural strength of porous concrete experimentally. Flexural strength of porous concrete became slightly lower with increasing of specimen depth. In this study, the size effect on flexural strength of porous concrete was as large as that of ordinary concrete. It was also revealed that the size effect due to increasing of specimen lengths was larger than that of ordinary concrete.
