Article Description

This paper studies the effects of recycled glass cullets as fine aggregates for the material in construction 3D printing. A reference material with natural river sand as fine aggregate was used as the control and recycled glass cullet of similar grading was used to replace the natural river sand at 25, 50,75 and 100% by mass. The effects of incorporating the recycled glass on the rheological properties such as the static yield stress, dynamic yield stress and plastic viscosity were studied. 3D printing investigation was also conducted on the mixtures to evaluate the materials printability (pumpability and buildability). Mechanical properties such as compressive strength and interlayer bond strength by splitting tensile were also examined. Results show that the static yield stress decreases while the dynamic yield stress and plastic viscosity increases as the recycled glass cullets content increases. The change in rheological properties also affected the printability of the mixtures. In the mechanical properties test, the increase in recycled glass cullets content also reduces the compressive strength and interlayer bond strength of the specimens.
