Abstract
This paper presents the performances of a 3D printable ductile fiberreinforced geopolymer composite (3DP-DFRGC). An ambient temperature cured one-part geopolymer was utilized as the binder for manufacture of the developed 3DP-DFRGC, which eliminates the necessity for curing at elevated temperature and handling of user-hostile alkaline solutions. Herewith, it considerably enhances the possibility of in-situ applications and commercial viability of the 3DP-DFRGC. The rheological behavior and mechanical properties of the 3DP-DFRGC were experimentally characterized. The mold-cast DFRGC was also prepared and tested for comparison. The 3DP-DFRGC exhibited pronounced deflection-hardening behavior under bending. The modulus of rupture and the corresponding deflection of the 3DP-DFRGC were 18% and 28% higher, respectively than those of the mold-cast DFRGC. This can be due to the preferential orientation of fibers in the 3D-printed specimens.
