Recycling of tunnel excavation using the example of the Koralm Tunnel, contract KAT2 – Status April 2015 / Verwertung von Tunnelausbruch am Beispiel des Koralmtunnels, Baulos KAT2 – Stand April 2015

Abstract: A 3D model for the prediction of the effective thermal conductivity of porous building blocks is introduced. Simulations are performed directly on the microstructure using voxel images and the finite element technique. Very good agreement with analytical solutions is achieved. The model is used to investigate the miscalculation effect of 2D simulations, clearly indicating the need for a 3D model. Furthermore, a method for incorporating radiative heat transfer at the microscale is implemented and applied on a s… Show more

“…The Koralm tunnel delivers a faster connection between the counties Styria and Carinthia. Contract KAT2 produced about 8.6 million tons of excavated rock and soil (Posch et al, 2015b), whereas about 50% of the suitable tunnel spoil was preliminarily screened, divided into four classes and used for concrete aggregate production including high-strength concrete with a main purpose of inner lining element casting (Posch et al, 2015b;. Investigations on iron and aluminium eluate concentrations were performed and included tests of selected additives such as cement or resin foam (Posch et al, 2015a).…”
