Abstract: In this study, standard fire test were carried out on SCC with water/cement ratio of 0.41 and 0.48 and HPC with w/c ratio of 0.33, on specimens 300 × 300 × 150 mm. Polypropylene fibers (PP fibers) were added to the concrete in order to examine the reduction of spalling damage at elevated temperatures. The experiments were carried out at curing ages of 3 months and 9 months. The temperature increase in the furnace followed the standard ISO 834 curve. It was concluded that explosive spalling occurred on some SCC samples after about 20 minutes of fire exposure. The relations between temperature history, internal pore vapour pressure and microstructural changes of SCC at high temperatures are discussed.
