Abstract: This review gathers the methodologies, issues and challenges concerning to large-scale fire experiments on concrete tunnel lining. Firstly, the study reviews fire testing of concrete tunnel lining, large-scale rather than small-scale and effect of tunnel fire on spalling of fireproof concrete. Secondly, issues surrounding the tests, including new fireproof concretes which involves high strength, high performance which normally containing various pozzalanic cementitious materials such as fly ash, silica fume and nanosilica which are very dense and behave explosively during fire are discussed. The main challenge for large-scale testing is that the influenc es of the specific spalling measures are difficult to predict and compare with others given the distinctions in testing setups and types of fire curves that are applied to obtain results. Current contributions in large scale fire testing are to improve fire-resistant concrete and to support the advancement of the large-scale fire testing of concrete tunnel lining.
