In this study, the corrosion rates of the local and imported reinforcing iron present in the local market were calculated in the following water media (drinking water, rain water, sea water) in a manner that lost weight in the times (192 - 960) hours at room temperature, where the obtained results indicated that The highest rate of corrosion of the reinforced iron with its local and imported types was in sea water, and the results also indicated that the local reinforcing iron was less corrosive than the imported iron by a slight difference in all water media used in this study, and the effect of adding the compound of sodium phosphate dihydrogen dihydrogen was also studied ( Sodium di hydrogen phosphate monohydrate) as a corrosion inhibitor to its domestic and imported rebar in seawater as the most aggressive medium in iron corrosion, as the results of the study showed that the ratio of the efficiency of the damper in domestic and imported rebar was close, as it reached 84.23% in local iron when A time of 192 hours (8 days), and in imported iron it reached 83.53% at a time of 192 hours (8 days), and then the efficiency of the damper began to decrease with the passage of exposure time as it reached To 79.94% and 79.03% for domestic and imported rebar, respectively, at a exposure time of 960 hours (40 days). Although they are considered relatively highly effective, they can be used as an inhibitor to reduce wear.
