چکیده مقاله
Self compacting concrete SCC is a highly workable concrete characterized by extreme fluidity that can flow through heavy reinforced and complex structural elements under its own weight and without any vibration The literature indicates that while many research are available on mechanical property of SCC there are a few studies on durability property of SCC like permeability Permeability leads to moisture and destructive ions penetration and, thereby, to corrosion of the embedded reinforcement in concrete members Silica Fume SF is an additive material which can improve permeability of concrete The amount of added SF gives high strength and chemical resistance of concrete In this research SF is recognized as an accepted concrete additive and the effects of this material on permeability and strength of SCC is comparing with usual SCC samples Finally best replacement percentage of SF is estimated to achieve best permeability position with the same water to cement ratio
