Incorporation of waste glass dust with pigments containing Cd, S, and Se into magnesium oxychloride cement for sustainable production using 3D printing
Original language description
This study explores the incorporation of ultra-fine coloured waste glass containing cadmium, sulphur, and selenium pigments into magnesium oxychloride cement (MOC) formulations for sustainable construction applications, including evaluating the preparation feasibility of the cementitious paste for subsequent 3D printing development. The glass waste, in the form of fine powder originating from red glass bead production, was added to MOC mixtures in varying amounts (3%, 6%, and 9%). The composites were evaluated for structural, mechanical, thermal, and environmental performance. Results showed that the addition of glass dust had minimal impact on porosity, thermal properties, and colour of the cement, while slightly improving compressive strength and water resistance. Microstructural analysis confirmed the presence of dense intergrown MOC phase 5 crystals, and leachability tests indicated negligible environmental risk. It was demonstrated that the material can be produced using 3D printing, and the setting time increases slightly with a higher glass dust content. The findings demonstrate the feasibility of reusing specialised industrial waste in high-performance, eco-friendly construction materials.
