Abstract

This paper presents the influences of nano-CaCO3 (NC) on the fresh-state and hardened performances of 3D printing cementitious materials (3DPC) with limestone powder (LS). The LS was added at a rate of 15%, while 0, 1, 2, and 3% NC as a partial replacement for LS. Results show that the addition of NC accelerates the hydration reaction of Portland cement through nucleation. Besides, 15% LS increased the fluidity and vertical displacement but decreased the yield stress and green strength of fresh-state 3DPC. NC improved fresh-state performances of 3DPC significantly thanks to the high specific areas of NC. Mixtures containing 15% LS exhibited lower flexural and compressive strength than that of reference at all ages. However, mixtures containing 14% LS and 1% NC resulted in enhanced strength at all ages compared to mixtures containing 15% LS.
