The Role of the Granulated Blast Furnace Slag in Sustainable Cement Production and Waste Management
The Role of the Granulated Blast Furnace Slag in Sustainable Cement Production and Waste Management

Summary/Abstract: Sustainable development is a call to prudence and moderation efforts to reconcile key areas for humanity: ecological, economic and social development. Consistent with the idea of sustainable development is the use of by-products from other industries for the production of clinker, cement and concrete. These products can successfully replace natural minerals or clinker in cement production. This considerably reduces the extraction of natural resources and increases the economy of the process, without compromising the quality of the product. In cement production technology increasingly important role starts to play also active mineral additives. In the world's cement production process it has economic, ecological, but also technological base. The aim is in fact to obtain such cements whose properties will receive high durability concrete, and the use of suitable mineral supplements can be helpful in this. Known mineral additive is granulated blast furnace slag - waste coming from the steel industry. This material is increasingly being used also in the process of solidification of hazardous waste. The use of granulated blast furnace slag in the cement industry and in the process of solidification of galvanic sludge is presented in the paper with the presentation of the author's own research in this field.
