Solid waste management is one of the most important techniques in today's global manufacturing scenario. This project is done in view of utilizing the waste in an efficient manner for constructive purpose under eco friendly environmental conditions. In this study, the fine and coarse aggregates were completely replaced by fly ash aggregates in fly ash concrete .a mix design was done for M20 grade of concrete by IS method. Ordinary Portland cement of 53 grade was selected and fly ash aggregates

... ere prepared by mixing fly ash with cement and water. The properties of fly ash fine aggregates and fly ash coarse aggregates were studied. The aggregate crushing value and aggregate impact value of fly ash coarse aggregates were also studied. The cement and fly ash proportions of 15:85, 20:80 and 25:75 were tried with a suitable water content of 20% by total weight to get the fly ash aggregates. The concrete cubes, cylinders and beams were cast with the fly ash aggregates obtained from the above three cement fly ash proportions. Then the compressive strength, split tensile strength and flexural strength were tested and compared with control concrete. This paper briefly presents the compressive strength development of fly ash aggregate concrete at different ages. The split tensile strength and flexural strength of all the concrete mixes were also investigated at different days of curing.
