An Experimental Study on the Strength and Flexural Toughness of Steel Fiber Reinforced Concrete Using Fly Ash

This paper describes an experimental study on the strength and flexural toughness of steel fiber reinforced concrete using fly ash. The fly ash contents were varied from 0% to 20% of cement weight to explore the effect of fly ash addition with steel fiber reinforced concrete. as the result, the tensile strength, flexural strength and flexural toughness were increased remarkably as steel fiber contents were increased to 2.0 vol.%. Also, the steel fiber reinforced concrete containing 10% fly ash developed the highest strength. In the same contents of steel fiber, the flexural toughness characteristics show excellent when fly ash contents were 10% and steel fiber contents were 1.5 vol%.
