Abstract

Aiming at obtaining good shape stability after extrusion, accelerators are used in extrusion-based 3D concrete printing. Instead of injecting a liquid accelerator into fresh concrete, limestone slurry is proposed as a carrier for the dry accelerator in this study. As such, two pumpable mixtures (a Portland cement-based mixture and a limestone powder-based mixture) and a combination of these two mixtures (a combined mixture) were prepared. The flow behaviors and structural build-up were investigated, respectively.
