Abstract:
This work aims to investigate the buildability of geopolymer printing materials with silicon-to-aluminum (Si/Al) from 4.5-5.5 were prepared by addition different content of steel slag into printing materials matrix. Effects of Si/Al on the buildability of geopolymer printing were investigated by open time and rheology of fresh pastes. The results show that Si/Al ratios cause the change of buildability. Higher Si/Al of geopolymer printing materials is beneficial to buildability: longer open time, lower plastic viscosity, higher yield stress, and great thixotropic guaranteed the continuity and stability of structure in the printing system.
