ABSTRACT
The addition of lime to a soil has a pronounced effect on its physical and chemical properties. Two changes take place when lime is added to soil; the physical characteristics of the soil particles are altered and cementitious compound form resulting in some bonding of the particles. Lime fixation capacity (LFC) and initial consumption of lime test (ICL) were performed to compare and establish mix design for lime modification. Unconfined compression test was conducted to determine the strength development. Lime content at mix design has contributed to the increase in unconfined compressive strength (UCS) even to 10.5 times of the untreated soil strength. Crystallisation of cementitious compounds can be identified from X-ray diffraction (XRD) analysis and their morphology from scanning electron micrographs (SEM).
