Abstract

Expansive soil is found in many regions in Egypt, especially in the new desert cities including New Sohag City(town in upper Egypt). In this study, The soil samples were taken from the place of the Faculty of Veterinary Medicine at New Sohag University from a depth of 5 meters and it's used in the experimental program. The physical and mechanical properties of the natural soil were obtained. Then the soil was treated with chemical additives (Addicrete P and Addicrete BV) 0.5%, 1% and 2% by dry weight of soil. After treatment of soil the properties of the samples were investigated. The natural soil properties were used as control points for comparison purposes. The main results show that with increase of Addicrete P the plastic limit increases and liquid limit decreases, hence decreases plasticity index and it is revealed that a change of expansive soil texture takes place when Addicrete P are mixed with expansive soil. While Addicrete BV does not effect on the Atterberg limits or the soil texture of the soil. As the amount of “Addicrete P and Addicrete BV" is increased, there are an apparent reduction in optimum moisture content ,unconfined compressive strength, free swell, swelling potential and swelling pressure, and a corresponding increase in maximum dry density. The paper contains many important test results and these results were analyzed to establish optimum dosage levels for each of the treated additives. Based on the results obtained, it can be concluded that the expansive soil can be successfully improved by Addicrete P and Addicrete BV.
