In this paper, the authors investigate the possibilities of in-situ carbon capture and sequestration to eliminate spatial constraints from a chamber confined curing solution via CO₂ and steam integrated 3D concrete printing. The presented technology involves a two-step extrusion-based system that sequesters captured CO₂ directly into concrete prior deposition at the nozzle printhead, so as to achieve artificially accelerated carbonation reactions with enhancement of mechanical properties.
