Abstract

COASTAL STRUCTURES IN MIDDLE EAST ARE UNDER THE IMPACT OF HYDROSTATIC PRESSURES, SHOCK UPLOADING, DOWNFALLS FROM EROSION AND VARIOUS CYCLES OF FINAL TEMPERATURE RAGE CHANGES. CONSEQUENTLY, THESE STRUCTURES ARE BUILT FROM STRONG CONCRETE AND REINFORCED OR PRE-STRESSED STEELS. THUS, MAINTAINING RESISTANCE OF THE STEEL WITHIN THE CONCRETE IS HIGHLY SIGNIFICANT. THE PERFORMANCE OF CONCRETE IN MARITIME CONDITIONS AND MECHANICAL PROCESSES OF CONCRETE DESTRUCTION INDICATE THE FACT THAT CONCRETE PERMEABILITY IS THE CRUCIAL FACTOR IN DETERMINING ITS DURABILITY. THE FACT SHOULD ALSO BE CONSIDERED THAT EXCESSIVE COVERAGE INCREASES THE WIDTH OF THE CRACKS ON THE CONCRETE COVER SHOULD BE CONSIDERED, WHILE NOT ENOUGH COVERAGE CAUSES THE EASE OF PENETRATION OF SALTY AND CORRODING WATER IN THE CONSTRUCTION. IN THIS ARTICLE, THE ESSENTIALS OF MAKING A DURABLE CONCRETE IN MARITIME ENVIRONMENTS ARE DESCRIBED AND THE NECESSARY RECOMMENDATIONS ABOUT THE CONSTRUCTING MATERIALS, THE IMPLEMENTATION METHODS AND PREVENTING THE FUTURE CRACKS FROM HAPPENING ARE PROPOSED. ALSO, IN ADDITION TO THE ESTABLISHED PROVISIONS, SINCE IN CRITICAL ENVIRONMENTAL CONDITIONS, MORE CONSERVATION AGAINST EROSION IS NEEDED IN ORDER TO LOWER THE CONCRETE PERMEABILITY, THE ARMATURE CONSERVATION METHODS SUCH AS CATHODIC PRESERVATION, IMPLEMENTATION OF THE CHEMICAL PREVENTERS, USING ORGANIC AND NON-ORGANIC COVERS AND IMPLEMENTING ANTI-EROSION ALLOYS FOR THE ARMATURES ARE DISCUSSED ARE DISCUSSED AND THE RESULTS ARE PRESENTED.
