Building underground constructions results in huge amounts of excavation material, which is usually dumped or used as bulk material. But this material is a potential substitute for mineral resources. The intended purpose results in saving resources of mineral raw materials and has a positive effect on the environment. The usage of excavation material depends on petrological properties and the industrial demand for raw materials. Companies that process mineral raw materials are often situated close to a tunnel-project. The requirements for raw materials by those companies often correlate with the mineralogy of tunnel excavation material. For example, for the presented infrastructure project within this thesis the focus is on the chemical properties of mineral raw materials. If the excavation material correlates to the chemical requirements of the industry, it can be used directly by these industries. The excavation volume of the 27 km long Semmering Base tunnel with two tubes will be about 5 Million m³ which are planned to be dumped on a disposal site. To tap the full potential of raw materials, ranges of higher valued applications are shown for the lithologies in the project-area. In detail, the chemical compositions of the relevant rocks are compared with the requirements of the product processing industry. If the excavation material correlates to chemical requirements of the product processing industry, they can be supplied with tunnel excavation material. The goal is to provide the industry in the project-area with the usable tunnel excavation material. As part of this thesis, an existing evaluation matrix for tunnel excavation material was improved. The evaluation matrix was extended with the requirements of the raw material industry and demonstrates the potential for application of excavation material.
