More sustainable precast concrete elements are emerging utilizing high-performance, self-consolidating, fibre-reinforced concrete (HPSCC) reinforced with high-strength, lightweight, and noncorroding prestressed carbon fibre reinforced polymer reinforcement. One example of this is a new type of precast carbon FRP pretensioned HPSCC member intended as load-bearing elements for building envelopes. Their performance in fire must be understood before they can be widely used with confidence. It is known that the bond strength between both steel and FRP reinforcing bars and concrete deteriorates at elevated temperature and that high strength concrete tends to an explosive spalling failure when subjected to a fire. The bond strength reductions in fire, their impacts on the load-bearing capacity of prestressed concrete elements, and the spalling behaviour of HPSCC remain largely unknown. This paper gives insight in the fire behaviour of CFRP prestressed HPSCC slabs and presents selected results of an experimental fire test study on thin-walled slabs.
