Anoop Sharma, Dr. B.S. Walia "Effect of Phosphogypsum and Fly ash on the CBR and UCS of clayey soil", International Journal of Engineering Trends and Technology (IJETT), V50(5),266-270 August 2017. ISSN:2231-5381. www.ijettjournal.org. published by seventh sense research group

This paper describes the use of Phosphogypsum and Fly Ash for soil stabilization. Modified proctor test, California bearing ratio test and unconfined compression strength test were carried out. The fraction of Phosphogypsum is used in this paper is 1,3,5 and 7 along with fixed value of fly ash 20%. The different percentage were determined which showed considerable enhancement in the strength of treated soil. The maximum value of C.B.R. is at 5% Phosphogypsum and fly ash 20% . additional increase in ratio of Phosphogypsum the C.B.R. value decreases. The maximum value of U.C.S. is also at 5% Phosphogypsum and fly ash 20%. Experiment results show Phosphogypsum and fly ash enhances the strength properties of soil along with use of economical materials and also solves the environment problem.
