Abstract: The alkali-activated materials (AAMs) have demonstrated a noteworthy impact on both CO2 emission reduction with enhanced compressive strength (CS) and flexural strength (FS). In this work, the primary precursors hydrated lime (LM), paper sludge ash (PS), and fly ash (FA) were used for one-part AAM preparation. Waste foundry sand (WFS) was utilized as a substitute for the river sand. Impacts on the different characteristics of one-part AAM were evaluated under various mix designs.

The fluidity and rheology characteristics were assessed in the fresh state just after mixing, while the CS and FS tests were done at different ages after casting in the molds. The results revealed that FPL5 has maximum CS and FS in all the AAM mixes. The CS of FPL5 after 28 days is 31.6 MPa and FS is 5.94 MPa, which are 5.38% and 2.62% less than the CS and FS of the control sample (SC) respectively. The rheological data indicate a positive correlation between the plastic viscosity and the WFS. Yield stress rises as paper sludge (PS) content grows but decreases as WFS content increases. This suggests that the integration of waste foundry sand can enhance the mechanical properties of AAM. Furthermore, the rheological analysis indicates changes in fluidity and viscosity based on the proportions of paper sludge and waste foundry sand. Overall, these findings contribute valuable insights into optimizing sustainable and high-performance one-part AAM formulations, offering potential solutions for reducing CO2 emissions and advancing the field of eco-friendly construction materials.
