Feasibility study of using desalination brine to control the stiffness and early-age hydration of 3D printable cementitious materials

This paper proposes the use of desalination brine as a setting and hydration activator in set-on-demand 3D concrete printing. A series of tests were conducted to investigate the effect of adding different concentrations of desalination brine on stiffness evolution and early-age hydration of Portland cement mortars (PC mixtures) and limestone...
