The paper presents the Clay soils have the tendency to shrink when their moisture content is decrease and swell when their moisture content is increased. CCR is the one, which is produced in plenty of quantity. In each crusher unit about 20-25% of the production is CCR. In bulk use of CCR is possible through geotechnical applications as, Back-fill material, embankment, sub base material. It is a by-product of the acetylene gas production. CCR (Calcium Carbide Residue) as a treatment of soil is a technique to save Money and time on construction projects. Transform of clay soil into workable, compactable, friable material when CCR used. By CCR stabilization chemical changes in unstable clay soil which have long term effects. Experiments performed on CCR combined at different percentage with expansive soil .The test results such as Standard Proctors test, direct shear test, and unconfined compression strength obtain on clay soil. From this study conclusion drawn that the combination of equal amount of CCR is more effective, which is (5, 7, 9%) than the addition of CCR, to the clay soil in controlling the swelling behaviour.
