摘要：

The objective of our research was to develop an optimum concrete mix for fire resistance, that is usable for hollow core slab prefabrication. Small-scale and full-scale tests were done, and the results were used to calibrate a numerical model that can be used to determine the temperature and load capacity reduction of steel rein-forcement. With the help of the calibrated model, the effects of geometric variables were examined. The thickness of the ridge between the cavities has no effect on the change in the maximum temperature of the protected side in the examined 30-minute range, but the minimum temperature decreased.
