Abstract
Along with our rapid development of steel industry, the output of steel slag was increasing these yesrs. But all kinds of industrial waste emissions increased rapidly too. Application of good solid wastes such as coal ash and mineral powder is under low utilization rate, a large number of accumulation is serious threat to the environment and other issues. Therefore, research on the preparation of a new type steel slag ceramics with steel slag and coal ash is important to improve the industrial solid waste resource utilization. In this paper, the new type of steel slag ceramics was prepared by industrial waste steel slag and industrial waste coal ash, and the new type of steel slag ceramics was prepared by appropriate sintering process system. Meanwhile, the performance indexes of ceramic bricks were tested to determine the influence of different factors on the performance of the new type of steel slag ceramics.
Highlights
Steel slag, as a kind of solid waste slag formed in the process of iron and steel smelting, is mainly composed of different kinds of oxides such as calcium (Ca), iron (Fe), magnesium (Me) and aluminum (Al), and its composition is similar to ceramic materials

Summary
As a kind of solid waste slag formed in the process of iron and steel smelting, is mainly composed of different kinds of oxides such as calcium (Ca), iron (Fe), magnesium (Me) and aluminum (Al), and its composition is similar to ceramic materials. Application of good solid wastes such as coal ash and mineral powder is under low utilization rate, a large number of accumulation is serious threat to the environment and other issues. Research on the preparation of a new type steel slag ceramics with steel slag and coal ash is important to improve the industrial solid waste resource utilization. In this paper, steel slag and coal ash are used as the main solid wastes in the ceramic brick production process. Appropriate amount of industrial wastes such as coal ash are used to partially replace natural mineral materials. New ceramic materials of steel slag and coal ash are prepared by sintering method, and their properties and applications are studied
