This paper investigates the effect of curing environment on the strength and modal mineralogy of synthetically prepared acid sulphate soils (ASS) treated with lime and ground granulated blast furnace slag (GGBS). The treated samples were cured under various environmental conditions for up to 365days and tested for pH, unconfined compressive strength (UCS), and changes in modal mineralogy using powder X-ray diffraction (XRD). Quantitative analysis of XRD patterns (QXRD) was carried out using the Rietveld method. Results show that a lower temperature curing environment (15 wt ) are observed to have an adverse effect on the UCS after 180days of curing because of the formation of deleterious minerals (i.e.,thaumasite).
