The purpose of this research is to study the improvement of soil properties by the
addition of lime in certain percentages. The soil used in this study was obtained from the
Baseet region, which is located by the Syrian coast. We have studied the e
ffect of lime on
the consistency, the swell characteristics and the shear strength of soil.
The results of this study have shown a remarkable reduction of both liquid and
shrinkage limits, and the plasticity index with the increase of lime percentage. As for
plasticity limit, it increases in the beginning then decreases slightly with the rising of lime
percentage.
For the volumetric variation, the susceptibility of swelling and the shrinkage of
improved soil with lime decrease, and the free swelling and the swelling pressure become
almost negligible with 4% of lime.
Based on the shear strength results, we can indicate a notable increase in the friction
angle and cohesion of soil with increasing of lime percentage up to 8% of lime. After that,
these two factors decrease.
Through the soil stabilization we follow improvement of the physical
properties of the soil by adding chemical binding materials. This paper deals
with the treatment of soil samples collected from four locations in the south of
Syria, that would b
e used in irrigation canals basement . The binding
material used for the soil treatment is quicklime (CaO). After different
treatments the soil samples have a different behaviour after addition of Lime in
the same percent which reflects their ability to be stabilized.
