today , reducing the useful life , repairing and rehabilitating the damaged concrete structures caused by corrosion and other destructive factors in the harmful areas such as the coasts of the gulf of fars , damages the country 's economy and sustainable development in these areas . therefore , investigation and recognition of concrete in such areas is necessary to increase the useful life of concrete structures and prevent their early destruction . in this thesis which is in line with long - term research project , the effect of chloride ion on the corrosion of concrete and sulfate attack of self - compacting concrete in similar conditions of persian gulf , considering the conditions of locating and application of different elders , can be achieved by considering them in construction and construction of marine structures in the south of the country which are usually considered the most important structures of the country . in this research , by constructing self - compacting concrete and mortar samples and different mineral additives such as silica fume , slag and slag , two important parts of chloride penetration in concrete and the effect of magnesium and fixed cementitious materials were investigated electrical resistivity of specimens was measured in certain time intervals . also mass and length changes were measured for mortar samples . the results show that chloride diffusion is more effective in treatment setting . concrete specimens containing additives have lower ductility as compared to the control ones . also , penetration rate for concrete containing additives additives and silica fume can be increased . the results of war and the changes showed that mineral additives were very effective in sulfate attack . the addition of sds added an additive to the other samples in the sulphate attack . in all samples , there was a strong correlation between water absorption and electrical resistance and water absorption and ion diffusion was not found strong . also , the relationship between porosity and electrical resistivity and chloride penetration in concrete was investigated . according to the results , a model for predicting chloride ion penetration was presented.
