The present investigation brings out the experimental outcomes of the influence of two industrial solid wastes on black cotton soil. It evaluates the changes in compaction and strength characteristics of the black cotton soil on addition of these solid wastes. Disturbed soil sampling had been done and as per Indian classification system the soil is classified as CH soil. The virgin soil is mixed with varied percentages of Silica fume and Induction furnace slag independently and its effect on compaction characteristics was ascertained. The proportions identified for silica fume and Induction Furnace slag are in the order of 5 to 20% of dry weight of soil with an incremental increase of 5%. The optimum percentage of silica fume was obtained from the compaction characteristics of the soil. After choosing optimum percentage of silica fume, further the compaction and strength characteristics of the soil was ascertained with optimum percentage of silica fume and varying percentage of induction furnace slag ie 10 to 20% with 5% increase. The results shows that maximum dry density for BC soil + 10% SF +20% IFS is 1.63 g/cc and UCS for BC Soil + 10% SF +15 % IFS is 138.76 kPa.
