BASIC CONTROL PRINCIPLES FOR PRODUCING A HIGH PERFOMING NEW CERAMIC GLASS BY MIXING FLY ASH, FERRONICKEL SLAG AND WASTE GLASS

The combined land filled quantity of the fly-ash produced by a power plant and the slag produced by a ferronickel plant amounts to 3 (three) million tons per year in Kosovo. Due to environmental considerations, using this waste to produce new value-added materials constitute an efficient way to achieve waste sustainable processing.Development of technological processes for producing of high performing ceramic-glasses through mixing of waste glass, fly ash and ferronickel slag has been undertaken in cooperation with Canadian company FLOGEN. Fly ash from “Kosovo Energy Corporation” (Kosovo) and ferronickel slag from “New Co Ferronikeli” (Kosovo) (containing SiO2, CaO, MgO, FeO, Fe2O3, MnO, P2O5, Cr2O3, CaS, MnS, FeS as main components) and waste glass are jointly treated in order to produce a new ceramic glass with improved E-module and flexural strength (fracture) as compared to those produced by traditional aggregates. Depending on the mixing of components (fly ash, slag, and waste of glass) the ceramic glass semi-products can be used for the production of silicate tiles, pipes, decorative brick wall, etc.The purpose of this paper is to describe the basic control principles to achieve high performance properties based on the process parameters, treatment procedure, mixing ratios, concentrations of components.
