Improving the Properties of Swollen Clay Soil by Adding Lime

EasyChair Preprint 12722

Abstract

Clayey  soils  are  widespread  in  world.  Because  of  their  disadvantages,  the  need  to  be stabilized  becomes  more  and  more  urgent.  Enhancement  of  clayey  soils  using  mineral additives was well established in the literature.

This research aims to add lime in certain proportions to study the improvement of soil properties. We studied the effect of lime on swelling properties and soil texture.

The results of this study showed, with an increase in the percentage of lime, a decrease in both the plasticity index, shrinkage, and fluid limits. The plasticity limit increases at first with an increase in the percentage of lime and then decreases slightly.

Regarding the volumetric variation, the shrinkage and swelling capacity of the soil improved with lime decrease, and the swelling pressure and free swelling become almost negligible with 4% of lime..

Keyphrases: Key Words: swelling, clay lime, clayey soils, shrinkage
