Sewage treatment plants produce large quantities of sewage sludge as by-products, as the sludge contains elements harmful to environment. Such study investigated of utilizing different percentages of sewage (7, 14 and 21%) of soil weight. The stabilization / solidification process was used to improve the properties of the organic soil and meet its requirements. This technique was the use of traditional and nontraditional additives such as cement and styrene acrylic. The major objective of that research is to evaluate efficiency of stabilized soils through comparison of stabilizers. The organic soil was prepared and stabilizers were added in different proportions (3, 6 and 9%) for the purpose of the tests. Mechanical tests (Unconfined Compressive Strength (UCS) and Hardness) were used for the soil sample to estimate the best mixing and obtaining higher strength. Through outcome of the UCS and hardness tests, cement was most effective agent of styrene in terms of improving the properties, strength and hardness of the organic treated soil.

Keywords : Sewage Sludge, Soil, Stabilzation/Soldification, Stabilizers, unconfined compressive strength.
