摘要

•Sustainable binders incorporate limestone powder and a retarder/accelerator combination.•Matching limestone and cement surface area provides similar performance at various substitutions.•Rheology and calorimetry provide valuable quantitative information on potential printability.•Accelerator provides stiffening by reacting with available aluminates as opposed to silicates.
