| Abstract In this research, five concrete mixes were prepared, made samples for compressive, Splitting, bending and modulus of elasticity test have been use five of silica fume percentages and three of steel fiber percentages. According to results of this study, addition of steel fiber cause increase in compressive strength, splitting strength, bending strength, modulus of elasticity, and increase the angle of stress-strain curve. Addition of silica fume cause increase in compressive strength, splitting strength, modulus of elasticity, increase the angle of stress-strain curve while cause decreasing in bending strength. The higher compressive strength percentage was (32%) as compared to reference sample prepared at ninety days with silica fume percentage (5%) and steel fiber (0.5%), The higher percentage for splitting strength was (42%) while the highest percentage for modulus of rupture (33%), The highest ratio for modulus of elasticity (27%).
