Physico-chemical characterization of slag waste coming from GICC thermal power plant

The new gas installations of combined cycle (GICC) thermal power plants for production of electricity are more efficient than conventional thermal pow er plants, but they produce a high quantity of wastes in the form of slags and fly ashes. Nowadays, these by-products are stored within the production plants with. until now, no applications of recycling in other industrial p rocesses. In order to evaluate the capability of these products for recycli ng in glass and ceramics inductory, an investigation for the full character ization has been made by usual physico-chemical methods such as: chemical a nalysis, mineralogical analysis by XRD, granulometry, BET, DTA/TG, heating microscopy and SEM/EDX.
