PROPERTIES OF AGGREGATES OF STEEL-MAKING SLAG

During the latest period of time, a significant effort to fully use all kinds of by-products can be noticed both in our country and abroad. A lot of metallurgical and chemical production by-products that have hitherto commonly been piled up, are now tested for possible and effective use. In building industry, conclusive factors for the use of waste materials are their general properties and chemical composition, which should comply with valid technical standards. It is therefore necessary to continuously monitor the properties of waste materials, including steel-making slag, are dealt with. As in building industry it is possible to use waste materials and to build them in the road structure, it is important to know how particular waste materials will behave in particular structural layers and, of course, whether required criteria on particular pavement structural layers will be met when using waste materials. The use of steel-making slag for road structural layers requires a regular testing of its general and chemical properties. /Times New Roman, 12/
