Abstract
The study investigates the effect of three chemical accelerators, nano-C-S-H solution agent (NCSH), organic composite accelerator (OC), and an aluminum sulfate-based accelerator (FA), on the performance of lowclinker 3D printing mortar. The mixture with 80% clinker replacement, consisting of 20% cement, 40% limestone filler, and 40% slag was set. Using 2% OC significantly enhanced the compressive strength, increasing 3- and 28 day compressive strength by 47% and 18%, respectively, compared to ref mixture. Adding 2% OC can accelerate setting time by 35%, compared to the ref mixture. The OC-type accelerator was recommended for low-clinker 3D printing mixture.
