摘要:
Geopolymer Mortar was prepared using Alkali-Leached Lead-Zinc Slag Powder (ALSP) and metakaolin (MK), and its properties were verified through mechanical analysis, XRD, and SEM. Results showed that the optimal conditions—an alkali activator modulus (M) of 1.0, a liquid-to-binder ratio (R ltb ) of 0.50, and an binder-to-sand ratio (R bts ) of 0.30—resulted in maximum 28-day compressive and flexural strengths of 44.49 MPa and 5.54 MPa, respectively. This is due to the formation of a complex, dense silico-aluminate gel from the reactive silico-a...
