Abstract
Expansive soils lack the required engineering properties for use in pavement subgrades, and as a foundation supporting layer under buildings. In the present study red mud, a byproduct of bauxite industry is stabilized with lime and in turn is used to stabilize the expansive soil. Compaction studies and unconfined compressive strength studies were conducted in order to see the efficacy of these materials in improving the strength of the soil. Red mud is stabilized with 4% lime and lime-stabilized red mud is added to the expansive soil in different percentages varying from 10 to 50% in increments of 10%. Tests are also conducted on soils stabilized with lime-stabilized red mud and flyash, adding them in equal quantities along with 4% lime. The results show that red mud as well as red mud–flyash improves the geotechnical properties of the soil.
