    abstract = {Through the expansion of concrete in Persian Gulf Region and short-term burnout of existing
constructs considering critical and corrosive situation of this region, civil engineers and specialties are sought
to improve concrete production in civil infrastructures in Persian Gulf using nano materials. Nano technology
in recent years has drawn many attentions of researchers and scientists and its reason is using nanoparticles
and their unique physical and chemical characteristics. On one hand, the cement is a material that sticks the
parts of concrete and is used widely in construction projects. On the other hand considering its needs whether
in terms of rigidity, strength, durability and high performance as well as corrosion of armatures in concrete due
to the influence of chloride ions which is called as one of the durability and sustainability of reinforced concrete
structures, concrete industry is one of Nanostructure material important users. This study has been written in
order to improve the performance of Self-Compacting Concrete (SCC) using nano-silica in environmental
situation of Persian Gulf (corrosive) three total plans including self-compacting concrete, self compacting
concrete containing nano-silica and pozzolanic materials (micro-silica, fly ash and limestone powder) and their
results were analyzed after placing in two situations of corrosive and aqua (salty Persian Gulf). For investigating
the performance of mixtures above, the characteristics such as bending and compressive strength, the amount
of expansion, contraction, water absorption, ultrasonic, electrochemical corrosion potential, penetration of
chloride ion and the electrical resistance of examples located in ordinary water and salt destructive
environmental situation of Persian Gulf and pseudo Persian Gulf with almost 5% of salt for 180 days have been
investigated. Based on obtained results from the experiments, nano-silica improves the mechanical
characteristics of self-compacting concrete such as bending compressive strength and durability against
corrosive environments. In plans containing nano-silica and pozzolanic materials, it was observed that
mentioned samples have better characteristics than the samples with mere nano-silica. Within this, the plans
containing nano-silica and micro silicashowed better strength results besides concrete durability than other
samples in salt destructive situation of Persian Gulf like Persian Gulf.}
