In India most of the place is covered with BC soil which causes damage to the structures. Stabilization is the
process to improve the Properties of the black cotton soil. Chemical stabilization is more expensive than other type of
stabilization. But the main convenient to use the chemical method is that to control the setting time and curing time. The
performance of Calcium carbonate stabilized soil was evaluated using physical and strength performance test namely
Atterberg’s limit, Specific gravity test, Free swell index, Compaction test, CBR and UCS etc, with varying percentage of
Calcium carbonate i.e.0.25%, 0.5%, 0.75% and 1% respectively.
From the experimental results, it has been observed that various properties of soil added with this stabilizer at certain
percentage show remarkable positive changes as compared to the natural soil obtained. The main objective of this study is
to increase the stability of the soil and reduces the construction of cost by using locally available materials. The
effectiveness of CaCo3 is stabilizing the black cotton soil is available in this work
