In this research the influence of the fineness of natural
pozzolana and lime on the properties of compaction ,
unconfined compressive strength and linear shrinkage of
clayey soil was experimented the finessess of natural pozzolana
used in this re
earch were 3500,4000,4500 cm²/g , finessess of
lime 4000 , 5000 , 6000 cm²/g.
With the widespread of oil facilities, distribution centers of oil and oil tanks, it has become a must in this article to study the impact of these materials on the physical and mechanical properties of soils, especially at coast to avoid distortions
and changes in the properties of these soils.
We tried in this research to study Clay coastal soil. Two main samples were studied: one polluted with materials leaked from these sites and the other was not. The samples were taken from both types and transported to the laboratories of the Faculty of Civil Engineering at the University in October. In the laboratory, we conducted experiments and evaluated their results.
