Upcycling of roadway slabs with CO2 storage
Abstract
The use of recycled building materials holds great potential for resource-conserving and thus sustainable construction in civil engineering. Particularly in the case of larger infrastructure structures, such as track-bound roadways (Wiener Linien network: 253 km of underground railways and 417 km of tramways; ÖBB: > 5,000 km of rail network), large volumes of potentially reusable "building materials" are produced. The aim is therefore to reuse and install the track support slabs to be replaced as recycled aggregates for the production of new support slabs as close as possible to the installation site. For this purpose, a number of steps have to be investigated, such as the removal, the control of the mechanical stock parameters, the preparation process including the washing operations, the maximum reuse of the prepared concrete recyclate, a low demand for additional sands, the use of low-emission cements and reinforcement materials in the context of an optimised structural component design and the optimisation of the stripping and installation periods.
