Abstract: In this study, the effect of fly ash on concrete workability, compressive strength, splitting tensile strength and bond strength was investigated. The ordinary Portland cement was replaced with 5 to 50% fly ash, it was observed that 10 % fly ash showed the highest compressive strength at all ages, use of 15%-30% fly ash significantly increased the compressive strength at 90 and 180 days. The fly ash improved the bond strength of concrete at all replacement levels. It was concluded that 10%FA and 15%FA were the optimum replacement levels for all the investigated properties.
