This swell and shrink properties of soil might be quite dangerous for the structures build upon it as it would be responsible for the non uniform settlement due to which many heavy structures built upon it get collapsed which is the threats to the life of many human beings. These factors makes a lot damages to lightly loaded structures also like foundations, canal beds, canal linings, pavements etc. and this leads to a great problem for civil engineers. So it becomes necessary to enhance the geoparameters of such problematic soil with the help of stabilization technique. Soil stabilization is the easiest way to enhance the geo-parameters of soil with blending of additives. In the process of stabilization cementitious materials are found to improve the engineering properties of virgin soil. Utilization of industrial waste materials in improving the soil properties is an eco-friendly as well economical method.
covered by soil which is expansive in nature which is quite risky for the structures constructed over it, as it deteriorate by severely damaged due to expansion and contraction of expansive soil . So, proper modification method is needed to improve the engineering performance of swelling clays. The use of different additives like cement, lime etc as a stabilizing material is quite common. The use of industrial waste products as an alternative for these conventional binders is gaining more attention in recent times.
Around 85% of the residual product is still dumped into the ocean or stored in ponds or leaps them without purification. This kind of disposals causes harmful contamination. Reduction in the disposal of this by-product has economical and environmental benefits. The present work is carried out to establish the viability of using the combination of Brick Kiln Dust and calcium chloride and Rubber Fiber for stabilizing expansive soils. In experimental evaluation, the observations are made for different mixes like soil-Brick Kiln Dust, soil-Brick Kiln Dust- calcium chloride and Rubber Fiber at different proportions. Calcium Chloride has to kept constant for all mixes to obtain the base line values at 15 % and brick kiln dust percentage mixed in samples varies at 15%, 20%, 30% and 50% has been added to untreated soil with Rubber Fiber at the variation of 0.5%, 1%, 1.5% percentage. Test specimens were subjected under various tests such as unconfined compressive tests at 3, 7, 14 and 28 curing days. Free swell index test and Atterberg’s limit test were conducted. It is concluded that mixes with calcium chloride exhibited high strength, low plasticity index and low free swell index.
The effect of CaCl2, Brick Kiln Dust and Rubber Fiber on the soil and found that; the strength performance of modified mixtures is strongly influenced the weak soil by cement content, curing time and compaction energy. Increase in these variables lead to higher values of UCS. The types of cement used has negligible effect on strength development. With increase in the C3A (Tri-calcium Aluminates) content present in the cement leads to a decrease in the UCS of the mixtures for longer curing periods (A. B. Parreira, 2003). Brick Kiln Dust is an industrial waste which imposes many health and environmental hazards. Dumping Brick Kiln Dust in open area is not environmentally suitable measure as it degrades the quality of soil and water nearby the dumping area. Consistent infiltration of Brick Kiln Dust and Calcium chloride in the agricultural fields may infertile the agricultural land. On similar lines, Rubber is also the waste which can be utilized in constructional activities through Rubber Fiber that has been used in many roads' work across the country. (Rajagopalan Vasudevan, 2018) Padma Shri awardee pioneered the art of using plastic in road construction works and through this study

1.INTRODUCTION In India, there are several types of soil exists in which one type of soil is clayey soil which is very expansive in nature named as clayey soil, it contains some minerals of montmorillonite in it which makes it swell while
