Clay soil can be stabilized by the addition of small percentages, by weight, of lime, thereby enhancing many of the engineering properties of the soil and producing an improved construction material. As lime stabilization is most often used in relation to road construction, the tests were chosen with this in mind. This study describes a study on the performances of lime slurry stabilized kaolin clay. This study, effect of lime on kaolin clay soil has been investigated. The lime slurry was used in this study. The kaolin clay was mixed with various additions of lime slurry in four different proportions which are 10%, 20%, 30% and 40% lime slurry. The samples were cured from immediate to 14 days. In order to illustrate the strength of the samples, unconfined compressive stress tests were conducted by its curing period. The results of the study show that the soil maximum dry density is found to decrease while the optimum water content is found to increase with increase in the lime slurry content. The unconfined compressive stress increases with increasing addition of lime slurry and the time length of curing the samples. From the results the optimum mixture of lime slurry for kaolin clay was found at 20% addition lime slurry.
