Abstract: Concrete lining of tunnel are sometimes exposed to very high temperature due to traffic accident. Concrete lining must be designed to having the fireproof performance. In recent years, various fibers have been mixed in concrete structure for higher strength and durability. Such fiber reinforced concretes (FRC) have been employed for tunnel lining, which is constructed rarely as RC structure. Such fibers in tunnel lining are most important to prevent of exfoliation of concrete pieces. However, the property of FRC under fire temperature has not been investigated enough. This paper presents behaviour of FRC obtained from the fire-heating test, and reports gases from plastic fiber after fireproof experiment of concrete element. The experimental result showed that explosion of PFRC was smaller than explosion of normal concrete or SFRC. It was confirmed that poisonous gas for human is hardly occurred from plastic fiber.
