Dataset of "Surface modification of bulk material for particle bed 3D concrete printing – effect on wettability, porosity, and mechanical properties"

This dataset includes the data of the paper "Surface modification of bulk material for particle bed 3D concrete printing – effect on wettability, porosity, and mechanical properties".In the publication the surfaces of three bulk materials where modified using three different surface modifiers at different concentrations.The bulk materials are: 1. sand A, 2. sand B, 3. sand B/cement 60/40The surface modifications are: 1. nano-SiO2, 2. nano-TiO2, 3. DEG In the files, the measurementdata is assigned to a certain mixture with three attributes:1. "Host Material" which is the bulk material material used2. "Additive" which was used as surface modification3. "theoretical SAC (-) / layer thickness (nm)" which refers to the concentration of the surface modifier (Surface Area Coverage (SAC) for nano-SiO2 and nano-TiO2 and layer thickness for DEG) The document Particle-Size-Distributions.csv contains the particle size distributions of sand A, sand B and cement. The document Bulk-Densities_and_Porosities.csv contains the measured masses of the bulk density measurement as well as calculated solid densities based on the density of the mixture components. Further, the mean bulk densities and porosities are included. The document Draw-In-Speeds.csv contains the draw-in speeds of water into the mixtures. Further, the draw-in speeds of hexane as well as the calcualted cos(Theta) are included for the sand mixtures. The document Printing_Results.csv contains the printing results (compacted particle bed density, printed specimen density and 28d compressive strength) without and with curing for the printed sand B/cement 60/40 mixtures. The documents Hydration_sand-B-Cement.csv, Hydration_sand-B-Cement_05nm-DEG.csv and Hydration_sand-B-Cement_50SAC_nano-SiO2.csv contain the hydration results for the unmodified sand B/cement 60/40 mixture, the sand B/cement 60/40 mixture modified with 0.5 nm DEG and the sand B/cement 60/40 mixture modified with 50 % SAC nano-SiO2. The document SEM-Images.zip contains folders with SEM images of the uncoated sand A as well as the sand A coated with nano-SiO2 or nano-TiO2 at different SACs. The folders are named in the scheme "sandA_"Additive"_"SAC".
