The use of metallurgical slag for the synthesis of ceramics is considered as an alternative way to manage this waste. A significant effect on the physic-mechanical characteristics of ceramic materials when metallurgical slags are added is exerted by the heat treatment mode. Aluminosilicates were used as the main raw material metallurgical slags of lead and copper production were used as an additive-regulator of the properties of ceramics. It is shown that the addition of slag leads to an increase in mechanical strength. It was established that the maximum mechanical strength of 73.43 MPa is possessed by a sample obtained from a mixture of zeolite-bentonite-copper slag in the proportions of 50 % – 30 % – 20 %, at a moisture content of 15 % after calcination at 1,000 °C. © 2020, AIDIC Servizi S.r.l.
