Study on the effect of additives on the properties of mortar used in 3D printing technology with a small-diameter nozzle

This study evaluates the effect of admixtures on the properties of mortar used in 3D printing with a nozzle diameter of 5mm. The plasticizing additive Sika Plastiment 96 and the shrinkage-reducing admixture Sika Intraplast Z-HV, at varying dosages, were employed to design 20 mortar mix trials.
