Abstract

This note presents the effect of lime, cement, fly ash and ground granulated blast furnace slag (GGBS) on free swell index (FSI), liquid limit (LL), plasticity index (PI), compaction characteristics, hydraulic conductivity (k) and strength characteristics of an expansive soil. The effect of the above chemicals on California bearing ratio (CBR) was also presented. Lime content was varied as 0%, 1%, 2%, 4% and 6% and the amounts of other additives were varied as 0%, 5%, 10%, 15% and 20% by dry weight of the soil. FSI, LL and PI decreased significantly with increasing additive contents. Compaction characteristics also improved with increasing additive contents. Strength characteristics showed improvement at higher additive contents especially at higher curing periods. CBR (determined in soaked condition) also increased significantly with increasing additive contents.
