Abstract: By 2025, there will be insufficient drinking water according to a report of the world meteorological organization (WMO). In order to provide drinking water it was found that the use of seawater in the concrete industry was necessary. Researchers in the last decade’s findings have revealed some very important facts, but still it remains to be a dynamic subject for further study about the chemical deterioration of concrete for sea water used. This research presents an experimental study of the effect of sea water in concrete mixture, Totally 57 specimens (27cubes, 18cylinders, 12columns) where tested. The concrete cubes were going to be cured for 7, 28 and 96 days. The cubes were divided into three groups, group (A) concrete is mixed and cured in fresh water (FF). Group (B) was mixed and cured in seawater (SS), while group (C) mixed in fresh water and sea water (FS) by 50%. From the experimental results it was found that, The compressive strength in concrete mix B (SS) was higher than concrete which mix A (FF) and mix C (FS) by 31% and 7% at age 7 days, but at age 28 days the compressive strength in concrete mix A (FF) was higher than concrete which mix B (SS) and mix C (FS) by 4% and 10%, and at 96 days the compressive strength in concrete mix A (FF) was higher than concrete which mix B (SS) and mix C (FS) by 13% and 18%, due to the chloride contains tends to accelerate the setting of cement and may be due to salt crystallisation formation facing the strength gain.
