Résumé
This study investigates the anisotropic properties of a novel and sustainable graphene derivative, specifically a date syrupbased graphene-coated sand hybrid (D-GSH), incorporated into 3D-printed cement mortar (3DPC).The flexural strength of 3D-printed beams was determined after 7 days of curing by varying the loading directions, i.e. parallel and perpendicular to the printing direction for the mixes containing D-GSH, and the results were compared with a mix containing silica fume.The flexural strength increased when the force was applied parallel to the printing direction, which is due to better load distribution and stronger bonding of the 3DPC.In contrast, when the load was applied perpendicular to the printing direction, the strength was reduced due to weaker interlayer bonding.For example, a mixture with 5% silica fume showed a 25% increase in flexural strength when the load was applied parallel to the printing direction as opposed to perpendicular.On the other hand, mixes with 0.3 wt% D-GSH and 0.5 wt% D-GSH showed improvements of 11.6% and 9.5% respectively.As a result, adding D-GSH reinforced the layer interface and reduced the variance in flexural strength between the two loading orientations, thereby enhancing interlayer bonding in the 3D-printed structures.
