摘要：

Several properties of the HPC samples without and with polypropylene fibres addition. It was found that the dispersed reinforcement with polypropylene fibres increase the compressive strength after heat treatment of samples at 100 degrees C to 600 degrees C. However, the permeability of samples was significantly increased. Also the water surface absorption of these samples was drastically enhanced. The author made the conclusion that this significant increase of permeability in case of HPC samples with addition of polypropylene fibres will cause the enhancement of durability of this concrete at elevated temperature.
