Due to the increased construction of offshore concrete structures and the use of de-icing salts for the purposeof snow removal, the needs for the development of anti-corrosive concrete are increasing. To solve theseproblems, an evaluation of the mechanical and durability properties for concrete were conducted by mixingmodified-sulfur as 0 %, 5 %, 10 %, 15 % cement weight ratio. Both strengths and the properties affectingdurability such as water absorption coefficient, chloride ion permeability, accelerated carbonation resistance,rapid freezing and thawing, and chemical resistance were evaluated. All evaluations performed were accordingto the test specifications associated KS. The results indicate that mixing of modified-sulfur lowed chlorideion permeability and improved chemical resistance.
