Abstract: The present study investigates the use of natural pozzolana combined with lime for ground improvement applications. Laboratory tests were undertaken to study the effect of natural pozzolana, lime or a combination of both on the physical and the mechanical characteristics of cohesive soils. Natural pozzolana, lime and natural pozzolana-lime were added to two cohesive soils at ranges of 0-20 and 0-8%, respectively. Consistency, compaction, undrained traxial shear and unconfined compressive strength tests were performed on untreated and treated soil samples to assess the physical and mechanical characteristics of the soil. Treated samples were cured for 1, 7, 28 and 90 days. The results show that the cohesive soils can be successfully stabilized by combining natural pozzolana and lime.
