In this study, the coarse aggregates are completely replaced by fly ash pellets in fly ash concrete. A mix design was provided for M-25 grade of concrete by IS-10262:2009 method. Ordinary Portland cement of 43 grade and fly-ash and water was mixed with proper proportion to make the flyash pellets. The physical properties of fly ash pellets were studied. The cement and fly ash proportions 10:1, 5:1 were mixed with suitable water having water cement ratio of 0.3 to get the fly ash pellets. The concrete block of cube and cylinder-shaped were casted with fly ash pellets obtained from the above two cement fly ash proportion. Then the compressive strength was tested. This paper briefly presents the compressive strength development of fly ash aggregate concrete at different days of curing along with the cost of the cube casting in laboratory scale
