Trials were made for reprocessing Egyptian blast furnace slag with and without additives or commercial batches to produce glasses. X-ray diffraction studies were done to identify the crystallization phases separated by two steps regime for controlled crystallisation. The corrosion behaviours of the prepared glasses and corresponding glass ceramics by different leaching solutions were done at both room temperature for 1 and 2 months and at 95 deg C for one hour through the grain method. A further corrosion test inside a gamma-irradiaiton chamber was carried out for both the reference vitrified slag and the highly promising glass sand glass-ceramic samples under direct gamma irradiation facility. Infrared absorption spectra of the prepared samples were measured to identify their structural building units.
