Analysis of some properties of model system from low-melting illite clay and fibrous mineral wool waste

In recent years, recycling of fibrous mineral wool waste has become an acute problem. The present paper addresses this problem by suggesting a promising technique based on using fibrous mineral wool waste and low-melting illite clay with appropriate additives. The results obtained have shown that by applying an adequate calculation method it is possible to predict the fusibility characteristics of a selected chemical composition. The SiO2-CaO- Na2O system with the oxides Al2O3, MgO and Fe2O3 influencing its fusibility is considered. Fusibility characteristics of the investigated systems have been calculated and their structural changes were analysed.
