This dataset contains the results of an experimental assessment of thermal conductivity. Additive Tectonics GmbH developed the tested material for large-scale applications of the Additive Manufacturing (AM) process of Selective Cement Activation (SCA). This material was used collaboratively for a façade demonstrator project "Breuer x AM" within the framework of the DFG-funded TRR277. The material mixture consists of a dry particle bed with portland cement and lightweight aggregates (lightweight expanded glass), which is selectively activated with liquid. The experimental thermal conductivity of the tested material accounts for overall 0.646 W/mK.
