Originální abstrakt

The article addresses the laboratory and technological verification of selected industrial waste as the corrective fuel component in the technology for the production of artificial sintered aggregate. The effect of the type of tested fly ash is also evaluated. Coal tailings, sludge from the paper industry, sludge from waste water plants and fly ash from incineration plants for communal waste were selected as alternative raw materials. Experiments showed that in addition to the fuel component, alternative raw materials have a high loss from drying. This significantly influences the course of granulation and consequent firing. Less suitable from a technological viewpoint was the sludge from waste water treatment plants and the paper industry. In addition to standard coal dust, the use of black-coal fly ash with an above-limit content of combustible substances or black coal tailings can be recommended. The optimal alternative correction component is brown coal tailings which contain a sufficient volume of combustible substances and clay component which increase wither manipulation, as well as the final strengths. In this manner, artificial aggregate can be acquired with comparable properties as the aggregate corrected by fine coal. Any negative effect on the environment was not proven.
