The expansive soils are known for their low compressive and shear strength and they present numerous challenges to geotechnical engineers during infrastructural development. The study is an effort to examine the utility of a leather industry waste product known as liming waste ash for enhancement of the compressive and shear strength of the soil. The effects of different curing periods on the relative parameters of strength have also been discussed. It was found that the curing of the soil-ash (LLWA) mix promotes the development of bond strength through formation of pozzolanic cementitious products and augments the shear strength parameters and the unconfined compressive strength (UCS) of the soil. An improvement of 270 and 380% was found in the UCS and cohesion of the soil respectively post 28 days of curing period along with substantial rise of internal friction angle up to 7 days of curing. The influence of LLWA and curing duration on the soil fabric and its relative effect on various strength parameters have also been explained at the microstructural level through SEM analysis on the uncured and cured soil samples.
