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

Abstract

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 and with the appropriate additives. The results obtained in the present investigation have shown that applying a corresponding calculation method it is possible to predict of the selected chemical composition fusibility characteristics. In the present investigation a system SiO2-CaO-Na2O with the oxides Al2O3, MgO and Fe2O3 influencing the system's fusibility is considered. Fusibility characteristics of the investigated system are calculated and its structural changes are analysed.
