Abstract :

Expansive type of soil which is also called as black cotton soil expands suddenly and starts swelling when it comes in contact with moisture. This soil shows less strength and other properties of soil are very poor. To improve the soil properties it is necessary to stabilize the soil by different stabilizers. Black cotton soil shows unpredictable behavior with different kind of stabilizers. Soil stabilization is a process to treat a soil to improve the performance of soil. The construction on Black Cotton Soil has always been a big challenge to geotechnical engineers Very less work is found to be carried out in this field hence authors got inspired to do the work under consideration. In this experimental study the ick dust is added to the soil in order to increase the soil strength and other properties of it.. In this study, the potential of burnt ick dust as stabilizing additive to expansive soil is evaluated for the improving engineering properties of expansive soil. The evaluation involves the determination of the swelling potential, linear shrinkage, atterberg�s limits, & compaction test of expansive soil in its natural state as well as when mixed with varying proportion of burnt ick dust ( from 30 to 50%). The practices have been performed on three proportions 30%, 40%, and 50% with expansive soil. The research result shows considerable reduction in swelling of expansive soil . With increasing amount of stabilizer swelling decreases. Maximum decrement in swelling has been noted in 50% of replacement of soil by ick dust. Also by increasing stabilizing content linear shrinkage reduces. Maximum decrement in shrinkage has been noted in 50% replacement of soil by stabilizer. Maximum dry density of soil is improving and optimum moisture content is decreasing with increasing stabilizing content. For increasing content of stabilizing agent ick dust atterberg�s limit values are also decreasing
