Experimental results for mechanical and thermal properties of SCA material

This dataset contains the results of an experimental assessment of thermal conductivity as well as density and compressive strength of the same material. The material composition is currently under development within the DFG-funded TRR277 at TU Braunschweig. The group A01 at the Institute of Building Materials, Concrete Construction and Fire Safety is developing the tested material for large-scale applications of the Additive Manufacturing (AM) Selective Cement Activation (SCA) process. The material mixture comprises a dry particle bed with Portland cement, fine aggregates (quartz sand with a maximum diameter of 0.5 mm), and methyl cellulose granules selectively activated with liquid, in a volumetric mixture of sand/cement = 60/40 with the MC dosage being 1 wt.% of the total mixtures weight. The experimental thermal conductivity of the tested material without water treatment accounts for 1.319 W/mK, and the specimen with water treatment is 1.414 W/mK. The respective densities and compressive strength values are 1.70 g/cm³ and 19.37 MPa for the specimens without water curing and 1.78 g/cm³ and 24.40 MPa for specimens with water curing.     «

The thermal conductivity was determined on three post-processed (cut, ground, dried) prisms with 40x40x160 mm³. A Hot Disk TPS1500 with a 6.4 mm sensor (Kapton 5501) was used for the measurements according to the hot disc method described in ISO 22007-2:2015-12, with three measurements each. One specimen "Probekörper 2 (W)" was stored in water bath for 7 days. The density and compressive strength was similarly tested on 3 prisms with cut plane-parallel surfaces after 28 days according to DIN EN 196-1 perpendicular to the orientation of the layers.     «
