This paper aims to investigate the extrudability (flow-ability and shape-stability) of concrete mixtures by using contour crafting (CC) as an automated construction process.
Several experiments have been performed for flow-ability and shape-stability of concrete mixtures. Experimental results were compared to understand significant factors and their interactions. After developing the empirical model for flow-ability, the model was validated.
The experimental investigation of varied combination of concrete components developed a mixture within constrains of the CC nozzle and improved the quality of the extruded part.
Several experimental samples were fabricated using CC, and the derived empirical model was validated after more than 700 h of work.
