Researchers at Nanyang Technological University, Singapore, have developed a 3D concrete printing process that captures and stores carbon dioxide (CO) during production. The method incorporates CO and steamby-products of industrial processesinto the concrete mix, where CO chemically bonds into a solid form.The method, described in Carbon Capture Science & Technology, demonstrates a reduction in cements carbon footprint, a material responsible for 8% of global CO emissions. The process has shown improved mechanical properties, including a 36.8% increase in compression strength and a 45.3% improvement in bending strength, and traps 38% more carbon compared to conventional 3D concrete printing.Additional findings include:Reduced Porosity: Open porosity decreased by up to 72%, improving durability and resistance to environmental factors. Enhanced Printability: The process improves printability, allowing structures to be built with a 50% increase in build height capacity...
