Abstract

The advent of robotic additive manufacturing (AM) techniques using cementitious mortars heralds a transformative era in the construction industry, albeit with challenges in assessing the properties of such innovative materials and technologies. This research investigates the geometric and mechanical properties of cementitious mortars tailored for robotic AM, highlighting the need to determine how different techniques and the incorporation of reinforcements affect their properties. Variants of mortars with no fibres, natural fibres (NF) and metallic reinforcements were formulated to assess the influence of these reinforcements on the properties of the mortars. The performance of these mortars was assessed using flexure and compression tests, and also digital twin (DT). The results show that the obtained material is orthotropic. Depending on the test, the directions with the lowest or highest resistance are different. It has also been observed that the incorporation of coconut fibres (CF) or screws can, under certain conditions, improve mechanical performance at the expense of poorer geometric performance. On the other hand, sisal fibres (SF) cause a loss of strength but guarantee geometry consistency.
