A two and a half year research project by the German research association Kalk-Sand and the Institut für Baustoff-Forschung FEhS shows a new, environmentally friendly use for various metallurgical slags. Instead of natural stone such as basalt, they can be used in sand-lime bricks to increase sound insulation and compressive strength and to reduce the cost such as CO2-intensive use of lime. In the research project funded by the Federal Ministry of Economics and Climate Protection BMWK via the Working Group of Industrial Research Associations AiF, various steel mill slags as well as copper slags, ferronickel slag and rutile sand were examined. The FEhS Institute was primarily responsible for the characterization of the material and the assessment of the environmental compatibility of the stones, while the research association Kalk-Sand essentially oversaw the production of the stones in the technical center and in factory tests and determined typical stone characteristics.Further investigations are planned.
