The Impact of Mineral Salts and Milk of Lime on Physicochemical Parameters and Swelling :( Case of Clays of Tlemcen Algeria)

Abstract

Clay soil is the foundation for many buildings. So me families have the characteristic to be swelling or shrink. However, construction on this type of soil requires a good companion for the recognition of identification and characterizat ion of their swelling potential. In this work we are interested by two aspects:-The first is on the tests recommended for the identification o f four expansive soils in the region of Tlemcen (Algeria);-The second is to assess the influence of the addit ion of milk of lime and mineral salts (KCl Potassium Chloride, Magnesium Ch loride MgCl 2) at different percentages on the physico-chemical parameters, the swelling potential of these soils fro m co rrelations approximate estimates. The results obtained show that stabilization by the addition o f milk of lime mod ifies the physico-chemical characteristics of soil and the results are quite satisfactory in significantly reducing the phenomena of swelling, as regards stabiliztion with milk of lime we notethat the salt concentration has little influence on the potential of swelling and it differs fro m one another salt.
