Abstract

The uncontrollable setting time of white Portland cement restricts its application in 3D printed architectural decoration field. This study systematically investigated the effect of aluminum sulfate (AS) on the early-age rheological properties, hydration kinetics and structural build-up of 3D printed white cementitious materials (3DPWCMs). AS enhanced the dynamic, static yield stress (SYS) and thixotropy as well as structural stability of 3DPWCMs, among which 2% was considered as the optimized content due to moderate yield stress and reduced structure deformation. This improvement is attributed to accelerated formation of C-S-H gel and ettringite, driven by faster hydration of C3A and C3S with AS. In addition, a strong correlation was observed between bound water content and rheological properties evolution of 3DPWCMs with 2% AS over 50 min. Elastic modulus was found to be more reliable for predicting the printability of 3DPWCMs with AS. These findings offer mechanistic insights into the interaction between hydration and rheology during the critical early stage of 3D printing.
