Abstract

Geotechnical engineers are mainly concerned with the soil that lies below 3m from the earth surface. As the soil below this contains hard strata composed of rocks and different minerals. So we will conduct a series of experiments on the soil. Our main aim was to use the locally available soil, as we live in Jammu and Kashmir, the soil is mainly of clayey origin, so the available soil is treated in such a manner so as to influence the engineering properties such as shear strength , permeability in a desired manner. In our experiments we have used Sodium hydroxide, Aluminium hydroxide, Lime and Phosphorus Pentoxide in different proportions to influence the engineering properties of soil. As these chemicals have no adverse or bad effect on the soil as well as environment. As all these chemicals react with the soil in a rapid manner also influence the properties of soil. The important tests which are performed are Standard Proctor Test (S.P.T) and Unconfined Compressive Strength Test (U.C.S test). The Standard Proctor Test (S.P.T) is performed so as to obtain a graph between Optimum Moisture Content (O.M.C) and Maximum Dry Density (M.D.D). After getting the Maximum Dry Density (M.D.D), Unconfined Compressive Strength (U.C.S) has been performed to get the Unconfined Compressive Strength (U.C.S) value which has been determined as peak strength value and respective strain has been calculated from different observations
