Adding of Locally prepared nano-silica [1] to concrete improves the mechanical properties and microstructure of SF concrete [2]. Nano-silica was added with different percentages to the SF concrete to study their effect on the durability properties. Seven mixes were prepared with constant cement content of 400 kg/m3 and additional percentage of silica fume 15% of cement content. Nano-silica and nano ferrite was used at 1-3% and 1-2% of the cement content, respectively. The water permeability, the resistance of the MgCl2 on concrete and the resistance of the electro-chemical of accelerate corrosion. It was found that all the mechanical properties, especially compressive strength of silica fume blended mixes was improved using either nano-silica or nano-ferrite as additional percentages. Also, these properties were improved with increasing the nano-silica or nano-ferrite percentages. The results showed that adding 2% nano-silica was considered the most economical percentage with high properties.
