The amount of different minerals in tunnel excavation material varies in a large range. Therefor industrial clients-who could be interested in raw materials extracted from underground construction sites were investigated. Parallel to the development of advanced online technologies for analysing the excavated materials research is looking for important information regarding requirements for raw materials used in industrial process-es, which are grain size distribution, mineralogical composition, geochemistry as well as different water content-and water absorption properties.
