Set-on-demand Twin-Mix for concrete 3D printing Ghent University
A novel, set-on-demand concrete composition (“Twin-mix”) for 3D concrete printing applications was recently developed on a lab scale. Experimental proof-of-concept tests indicated that the Twin-mix concrete has significant advantages over the existing commercially available 3D printable materials, which include very high buildability/construction rate, low shrinkage, improved cost-effectiveness, and low environmental impact. Through this ...
