The fire performance of highly flowable reactive powder concrete (RPC) is of importance and necessary to be investigated prior to the application to building construction. By conducting a series of fire resistance tests, it is found that the residual compressive strength of RPC decreases with increasing fire duration. As compared to high performance concrete (HPC) and ordinary concrete (OC), the studied RPC not only has a higher fire endurance temperature but also possesses a larger residual compressive strength after fire. In addition, the experimental results of thermogravimetric analyses on RPC, HPC and OC specimens suffered from the same fire temperature and duration indicate that the total weight loss of RPC is lower than others. Besides excellent workability and high compressive strength, the studied RPC could provide better fire resistance than HPC and OC, and thus is applicable to building materials.
