     due to high humidity in coastal areas, concrete framework structures are more common than metal framework structures. however, corrosive ions and salts such as chlorine, sodium, various sorts of sulfates and destructive particles within fog made in these areas, in addition to continuous cycles of structures that become dry and wet ,cause aggravating in destruction of buried concretes in earth and concrete which is in the direct contact with air or sea water proximity. on the other hand, since light concrete generally has more porosity and higher water absorption, it has less strength against the adverse items. that is why deploying light concrete, in spite of its numerous advantages, has not been expanded in coastal areas. in sum, this paper dealt with analysis of effects of viscose materials, air entrainment and anti-sulfate cements upon concrete corrosion, it was done by performing pressure and electric resistance experiments, and comparing the amount of water absorption in the light concrete models that were constructed with artificial leca aggregate.
