In this paper, we describe the experimental results of soil stabilization, using the calcic refuse of the chemieal industry. A slaked line has been used as an addition for the stabilization of cohesion soil. This calcic refuse consists of Ca(OH)_2 (22.5%), CaO (5.8%) and CaCO_3 (56.8%) and it was mixed in soil at the rate of 5%, 7.5%, 10% and 15% power unit weight. At this result, it was cleared that this refuse is effective on the soil stabilization as same as a slaked lime is.
