A review on stabilization of clayey soil using egg shell powder (esp) along with chicken feather fiber (cff).

Abstract

Today the construction industry faces drastic problems because of availability of good quality of land for construction. This occurs due to increase in population and industalization. Overcome such situations civil engineers focus to construct structures on weak soil by improving its properties. The technique utilized for the enhancement of soil properties is known as ground improvement techniques. Here, a review on clayey soil treated with locally available waste materials, such as Egg Shell Powder (ESP) and Chicken Feather Fiber (CFF). Soil stabilization is the process of enhancing the physical properties of soil in order to improve its strength, durability etc.by adding different stabilizing agents. Egg Shell Powder is a waste product from homes, restaurants, etc. Chicken feather is also a poultry waste. Soil was first treated with varying percentage of ESP to find the optimum value for gain strength. Then the soil again treated with varying percentage of CFF along with optimum percentage of ESP to find optimum value to gain maximum strength. The study concluded that the addition of waste additives enhance the engineering properties of clayey soil. Both ESP and CFF are waste products which may cause severe environmental problems. The utilization of these products as soil stabilizers makes economical and become a best solution for sustainable environmental protection.
