A series of compaction tests and one-dimensional swell tests were conducted to study the effect of addition of various percentages of rice husk ash, fly ash, and stone dust on compaction and swelling behaviour of black cotton soil. Specimens were prepared by adding 4, 8, 12, 16 and 20% by weight of various industrial waste materials to the black cotton soil. Standard proctor test was adopted to study the compaction behaviour of mix. For swelling behaviour one-dimensional swell test was performed by fixed ring consolidometer. Test results have shown that the optimum moisture content (OMC) increases due to addition of rice husk ash while maximum dry density (MDD) decreases. However, slight decrease due to the addition of fly ash and no significant change due to the addition of stoned dust in MDD have been observed. Decrease in the OMC was observed due to the addition of fly ash and stone dust. Swell potential and swell pressure of the soil decrease with the increase in percentage of additives. It is found from the swelling tests that all stabilizers can effectively suppress the heave and swelling pressure, but rice husk ash is more effective in suppressing the swelling behaviour.
