Abstract – In the investigation, fly ash aggregates will be used in concrete and its effect on strength of concrete will be studied. The fly ash is collected in Mettur Thermal Power Plant. Then the cement and fly ash proportions of 12.5:87.5, 15:85 and 17.5:82.5 will be adopted to get fly ash aggregates. The particle size distribution, specific gravity, bulk density, impact test on aggregate will be conducted. The M20 grade of concrete will be considered. The fresh concrete tests Slump test and Compacting factor test will be conducted. For the plain concrete and fly ash aggregate concrete of beams (Plain concrete and RCC beams), cubes and cylinders will be cast. All the specimens will be cured in a curing tank. The conventional and fly ash aggregate concrete specimens will be tested for 7 days, 14 days, 28 days, 50 days and 90 days strength. The compressive strength, split tensile strength and flexural strength will be conducted on the concrete specimens. The result will be tabulated and compared by drawing bar charts. Based on the result obtained, conclusions and suggestions will be made.

Key Words – fly ash coarse aggregates (FACA), fly ash coarse aggregates (FAFA), fly ash pellets, compressive strength, split tensile strength, flexural strength, fly ash concrete, control concrete (cc)
