摘要：

This work characterizes the mineral composition, amorphous fractions and microstructure of various iron and steel slags by chemical analysis as well as by X-ray diffraction and electron microscope investigations. The results show that different German iron and steel slags differ in their chemical and mineralogical compositions as well as in their characteristic parameters, such as basicity and proportion of amorphous constituents, and in the levels of periclase. and free lime that are responsible for possible changes. The investigations have been carried out so that iron and steel slags can be put to appropriate use in the building materials industry. In particular, it was intended that the iron and steel slags could be used to reduce the risk of an alkali-silica reaction (ASR) in concrete.
