dc.description.abstractThis paper comprehensively focuses on the wetting-drying (W-D) behavior of carbonated marl soil, treated by a geopolymer utilizing alkali-activated milled recycled glass (MRG) and ordinary Portland cement. The effect of the stabilizer ratio (5%, 10%, 15%), curing times and temperature (24 h under 25 degrees C and 50 degrees C), sample preparation procedure (curing under a pressure of 200 kPa and in an oven), alkaline concentration (2, 4, 6 mol/L), pH, and different W-D cycles (1, 3, and 12 cycles) were assessed. Furthermore, this article explores the failure behavior of samples, a fact that has received limited attention in previous studies. Binding phases were examined using XRD, FTIR, and SEM-EDS techniques to analyze crystallinity and functional groups in stabilized specimens. The findings indicated greater efficiency in stabilization with lower alkaline activator concentration (2 mol/L), higher glass powder content (15%), and longer curing (90 days), which is abbreviated as 15S2M. Nonetheless, an excessive alkali content of 6 mol/L had adverse effects, leading to a decrease in the strength of the final product and a change in the failure pattern. Visual observations post UCS testing revealed four distinct failure modes, varying based on specific mixtures and curing times. In natural marl samples, irrespective of curing time, the failure surface and deformed shape exhibited a variation in cross-sectional area, with unclear failure planes resulting in a bulging or buckling failure mechanism. Notably, in low alkaline concentration scenarios and high MRG content, as well as in cement-stabilized samples, identifiable failure planes were observed, indicating shearing along a single plane or a sliding mode. The results also demonstrate the superior durability of cement-based samples during W-D cycles.en_US
