Abstract

In this paper the results of an experimental study on the behaviour of High Performance Fibre Reinforced Cementitious Composites under static and dynamic tension loading are described. This material has been de-veloped for new segment tunnel resisting to fire and explosion. Results have shown the influence on its mechanical behaviour in tension of high temperature and strain rate. The dynamic strength increases with high temperature exposure, and toughness is progressively reduced. A change in the failure mechanism has been observed in dynamic tests by increasing the exposure temperature.
