Title: Neutralization of cement-asbestos waste by melting in an arc-resistance furnace

Abstract

Highlights: • Interesting possibility for cement-asbestos wastes utilisation. • Product of thermal treatment of cement-asbestos may be considered as useful secondary raw material. • Complete destruction of asbestos fibrous structure by melting process in arc-resistance furnace. • Reduction of cement-asbestos waste melting point by flux addition. - Abstract: The paper presents the results of research on asbestos waste disposal by the melting process. The tests were carried out in a laboratory arc-resistance electric furnace. The obtained results showed that the fibrous structure of asbestos contained in cement-asbestos waste was completely destroyed. This led to the formation of new mineral phases without dangerous properties. The melting test was conducted on raw cement-asbestos samples without any additives and with a content of mineral compounds, the aim of which was to support the melting process. The additives were selected among others on the basis of the computer simulation results carried out using FactSage database computing system. The research results indicate that the melting process of asbestos wastes is a potential and interesting method of neutralizing hazardous asbestos waste, which allows for further treatment and material recycling.
