There structures are build up due to marine concrete development. These marine concrete long-term exposure to water occurs when the rebar corrosion or cracks destroyed. We study to improve this phenomenon. We had the Salt durability assessment that accompanies.

This study, depending on the concrete mix material by performing the test on the basis of the wet and dry condition and freeze-thaw, and to elucidate the difference in the corrosion initiation time of there steel, in both environments, it is an object of correlation coefficient derived through the results of the accelerated corrosion test in a laboratory corrosion period of the structure of the marine environment.

Industrial by-products in combination with FA, BS was excellent compressive strength, chloride penetration resistance by OPC 60(W/C 60%) based on the comparative analysis. The most effective periods were BS 28 days and FA 56 days.
