Abstract

CONCRETE HAS ALWAYS BEEN CONSIDERED AS ONE OF THE MOST USABLE AND DURABLE CONSTRUCTION MATERIALS FOR BUILDING DIFFERENT STRUCTURES SUCH AS MARINE AND BERTH CONSTRUCTIONS. IF THE MATERIALS AND THE TECHNIQUES ARE CHOSEN PROPERLY AND WITH SUITABLE PRESERVATION, THIS STRUCTURE WILL HAVE A GREAT DEAL OF DURABILITY. HOWEVER, INADEQUATE MATERIALS, INAPPROPRIATE AND LOW-QUALITY IMPLEMENTATION TECHNIQUES AND PROCESSING DEFICIENCY CAUSES DAMAGE TO THE CONCRETE STRUCTURES AND ARMED CONCRETE, ESPECIALLY IN WARM CLIMATES. IN THIS ARTICLE, NEAR-COASTAL AND PORT STRUCTURES IN THE SOUTH OF IRAN ON THE PERSIAN GULF WERE INVESTIGATED, USING THEORETICAL EXPERIMENTS ALONG WITH NON-DESTRUCTIVE, PHYSICAL AND CHEMICAL EXPERIMENTS AND SAMPLINGS ON THESE CONSTRUCTIONS. THE CHLORIDE ION PENETRATION EXPERIMENTS AND ITS AMOUNT HAVE INDICATED THAT THE CRITICAL FACTOR FOR THESE STRUCTURES DESTRUCTION IS ARMATURE EROSION, AND THE CRACKS AND SCATHES ON THE CONCRETE ARE BECAUSE OF THE PENETRATION OF THIS ION. THE CARBONATION AND HALF-CELL SUPPLEMENTARY EXPERIMENTS ALSO INDICATED THE SAME RESULT. IN SOME CASES, IMPROPER IMPLEMENTATION AND THE LACK OF THE NECESSARY CASING IN HIGHLY ERODED REGIONS CAUSES THE DESTRUCTION TO APPEAR MUCH EARLIER THAN EXPECTED. AFTER PRESENTING THE RESULTS OF THE MENTIONED EXPERIMENTS, AND ELABORATING ON THE REASONS, SOME RECOMMENDATIONS AND SUGGESTIONS IN ORDER TO INCREASE THE DURABILITY OF THE MENTIONED MARINE STRUCTURES, ESPECIALLY FOR WARM COASTAL REGIONS IN THE SOUTH ARE PRESENTED AT THE END.
