IMPROVEMENT OF ENGINEERING PROPERTIES OF EXPANSIVE SOIL WITH ADDITION OF EGGSHELL POWDER AND FLY-ASH

Soil is one of the most valuable materials used in a variety of construction project including earth work. The clay soil acts high strength in dry condition, but exhibit low strength in wet condition. Thus, variation in the characteristic behaviour of the expansive soil result major problem in the engineering properties during construction. Some different approaches are made in order to improve the soil characteristics. Egg Shell powder composition is near to that of lime so it increases the soil stabilization. In this project sample of clay in National Highway-16 near Narayana Engineering College, Gudur collected and conduct the basic tests for that soil sample. After analysing the properties of the soil, Egg Shell Powder has been added in proportion of 3%,6%,9%,12 %,15% and 18% and Fly Ash has been added in proportion of 4%,8%,12% and 16%. The laboratory tests conducted to determine Index and Engineering Properties of soil. By adding Egg Shell Powder and Fly Ash, the behaviour of the Engineering properties is analysed. From this investigation will determine effective percentage of egg shell powder and Fly ash need to be added to increase Engineering Properties of soil.
