The project analyses the comparison between two different waste materials i.e., Surkhi and Phosphogypsum; which areavailable easily and used as a replacement material with fine aggregate for the design of rigid pavement. Phosphogypsum is one of the by-products of the production of fertilizer obtained from the phosphate rock. Surkhi is powdered form of bricks.M30 grade of concrete is designed. Water cement ratio of0.45is used. Fine aggregate is replaced with surkhi in different proportions of 5%, 10%,15%, 20% and 25% and phosphogypsum in different percentages of 5%, 7%, 10%, 12% and 15%. This experimental study analyses that when surkhi was replaced with 20% and phosphogypsum with 10%; the compressivestrength values and flexural strength values both increased when they were compared with the normal concrete of M30 grade. Thisexperimental analysis is very much economical and also it reduces cost of the fine aggregate
