Abstract
In this research low plasticity clay (CL) has to be mixed by varying percents of gypsum and after that this mixture would be treated with different amounts of lime, in two methods: regular application and Double application. The swell examinations would be done on these samples; and the influence of sulfates and mixing method on different quantities of swell will be taken into consideration. The results show that the presence of sulfates causes an incredible increase in the swell. This increasing also is at times much more than the thing that is revealed in unimproved samples; but in improved samples from Double process mixing method the quantity of the swell would be decreased in large volume in comparison with regular method.
