Concrete is generally accepted to have good fire resistance. It mainly relies on the assumption that concrete has low heat-transfer characteristic and spalling does not occur during the course of a fire. However, the significant numbers of fire accidents have shown in recent years that incidence of spalling has caused sever damages to many structures. This research has investigated a series of catastrophic tunnel fires and tested on the behaviour properties of concrete in association with loading in fire. This paper present that the theoretical consideration and experimental results are used the information of concrete spalling.
