Durability of GGBS based alkali-activated binder treated peat through wetting-drying cycle
This research is aimed at investigating the effect of wetting-drying (NWD) cycles on pH, electrical conductivity, unconfined compressive strength (UCS), and mass loss of ground granulated blast furnace slag (GGBS)-NaOH stabilised sapric, fibric, and haemic peat. The ordinary Portland cement stabilised peats were selected as control samples for comparison. The microstructure of GGBS-NaOH stabilised peats before and after NWD cycles were analysed through X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), and Fourier transform infrared spectroscopy (FTIR). The pH, electrical conductivity decrease with increasing NWD cycles. The GGBS-NaOH-treated peats exhibits higher UCS values of 3.1, 4.2, and 1.2 times more than cement-treated sapric, fibric, and haemic peats respectively. The FESEM micrographs reveal the presence of smooth and dense cementitious materials before NWD cycles, and the presence of microcracks after NWD cycles. Further, the FTIR confirms the presence of physical water in cavities of treated peats after NWD cycles.
