Abstract

A new method for the disposal of hazardous asbestos bearing wastes is described; it is based on low temperature sintering of asbestos fibres-unzeolitized tuffs quarry dusts mixtures. Ceramic products similar to gres employable as floor covering both in public and industrial installations, have been produced. Mixtures containing up to 50 wt% asbestos fibres were prepared and moulded by dry grinding and pressing. In spite of the low moisture content, the presence of the fibres produces high strength moulded green bodies which were, without drying, fired at temperatures ranging from 1060 to 1180°C.
