Abstract

Stabilization of Black Cotton Soil (BC soil) is studied by using Marble dust, cement kiln dust and polypropylene fibers. BC soils are highly clayey soils (Montmorillonite clay mineral). The moisture changes in BC soils, compressibility and plasticity nature can be greatly improved with the addition of marble dust, cement kiln dust and polypropylene fibers. This paper includes the evaluation of soil properties like Optimum moisture content, dry density, and Shear strength. Different quantities of marble dust, cement kiln dust and polypropylene fibers (% by weight) are added to the BC soil and the experiments conducted on these soil mixes. The result shows that the use of marble dust, cement kiln dust and polypropylene fibers increases the strength of soil to a great extent. An experimental programme was undertaken to investigate the effect of marble dust, polypropylene fibers and cement kiln dust on the strength of Black cotton soil. In the present investigation soil is compacted at various percentages of marble dust (i.e.5%,10%,15%,20% by weight of soil), polypropylene fibres (i.e.0.05%,0.15%,0.25% by weight of soil), cement kiln dust (i.e.4%,8%,12%,16% by weight of soil). In above percentages of admixtures, we got 15% of marble dust by weight of soil, 8% of cement kiln dust by weight of soil, and 0.15% of polypropylene fibers by weight of soil has an optimum value. Again compaction is carried out for combination of black cotton soil with marble dust, cement kiln dust, and polypropylene fibres(i.e.15%,8%,0.15% by weight of soil respectively) and unconfined compression tests were carried out at immediate,7,14,21 days curing period .The test results indicated that the addition of marble dust, polypropylene fibres and cement kiln dust in black cotton soil shows an increase in unconfined compression strength, decrease in the dry density, increase in optimum moisture content. The results show increase in strength of expansive soil.
