According to test results, the conclusions that were extracted from the study were given as following. Soda lime
glass powder has an ability to improve the engineering properties of clay soil, and also it has a positive effect on
MDD, OMC and atterberg limits. California bearing ratio of clay soil increased when soda lime glass powder
increased. The results show that the addition of soda glass powder to clay soil can be used efficiently to reduce the
swell potential of soil. An improvement was observed for swelling potential of soil with respect to addition of 12%
soda lime glass powder to clay. Swelling value of the clay decreased from 5.5% to 1.65% incorporating with 12%
soda lime glass powder. With increasing curing time from 3 to 28 days, the hydration process is increasing between
the soil clay particles and glass powder, that's lead to increase the values of unconfined compressive strength of clay.
