Soil may be defined as all naturally occurring, unconsolidated mineral particles, organic or inorganic in character, lying over the bed rock which is formed by weathering (disintegration)of rocks. The fact that soil may provide all the resistance characteristics necessary for a project illustrates the importance of various methods used to improve soil quality. Most of the failures of soil and earthen dams have been attributed to poor strength. As we know stabilization of soil by adding lime, cement, bitumen etc. are expensive and therefore require an economic replacement. In this thesis work, I have studied about the suitability of Saw Dust Ash, Egg Shell Powder and Polypropylene as a possible additive material to improve the strength of soil. Soil samples were collected and stabilized with Egg Shell Powder in proportions of 1% to 4% at 1% interval by dry weight. The engineering properties were carried out to access the behavior of soil with the addition of eggshell powder. Addition of Egg Shell powder to soil sample lead to increase in unconfined compressive strength. The maximum unconfined compressive strength was attained at 3% Egg Shell Powder stabilization. Using of chemical admixtures such as lime, cement, bitumen etc. in soil stabilization is highly expensive. Therefore, it is preferable to replace these manufactured materials by other kinds of soil additives to reduce the cost. This research investigates an experimental study of improving engineering properties of soil with Eggshell powder, Polypropylene and Saw dust ash. The analysis was done by conducting Compaction, and California bearing ratio tests. It was observed that eggshell powder, saw dust ash and polypropylene had significant effect in the engineering properties of the soil. The results showed that the unconfined compression strength and California bearing ratio values had increased with increase in Egg Shell Powder, Saw Dust Ash and Polypropylene content up to certain limit. The aim of the present work is to study the effect of Polypropylene, Saw Dust Ash and Egg Shell Powder on the engineering properties of soil.
