In this research on the influence of the mass ratio of tailings to ceramic crucible residues on the compressive strength of alkaline mortars, finely ground powder from tailings and recycled ceramic crucible residues was used. Mechanical tests, according to ASTM C109, were conducted on cubic samples of 5x5x5 cm. The mass ratios of tailings and recycled crucible powders (5/7, 1/2, 1/3, 1/5, 1/11) were pre- experimentally selected based on compressive strength. The binder-aggregate ratio remained constant (2:1), while the binder-alkaline solution ratio was kept at 0.75. Alkaline activation was achieved with a NaOH solution (5M). The results indicate that the pre-selected mass ratios impact compressive strength, with the 1/3 ratio showing the most significant increase at 34.88% compared to 5/7. FTIR characterization revealed the presence of aluminosilicates in recycled ceramic crucible powders, and Si-O and Al-O bonds indicated the geopolymerization process. Modifications in functional groups, especially between 700 cm-1 and 1500 cm-1, suggest significant changes during alkaline activation. Furthermore, an inverse relationship between defects in alkaline mortars and compressive strength was observed, with values being directly proportional to curing time. The maximum average compressive strength value was 13.30 MPa for the 1/3 ratio, showing a 34.88% improvement compared to the 5/7 ratio (9.86 MPa). These findings suggest a crucial correlation between mass ratios and alkaline activation in enhancing compressive strength in these mortars.
