Effect of pozzolanic additives on index properties of expansive soils

Expansive soils are highly problematic by virtue of their innate capacity to undergo volumetric changes corresponding to changes in moisture content. These soils can be identified by their index properties sch as free swell index and liquid limit and plasticity index. This book is an experimental work on the effect of pozzolanic additives such as lime, cement, fly ash and pond ash on the index properties of expansive soils. Significant index properties such as liquid limit, plastic limit, plasticity index and free swell index were studied at varied amounts of lime, calcium chloride, cement, fly ash, pond ash and GGBS.
