CONCRETE IN MARITIME WORKS

MARITIME CONSTRUCTION PRESENTS PROBLEMS THAT ARE NOT ENCOUNTERED INLAND. IN DISCUSSING THE PERFORMANCE OF MARITIME STRUCTURES, VARIOUS TYPES OF DAMAGES THAT OFTEN OCCUR ARE DESCRIBED AND IT IS POINTED OUT THAT THE CHOICE AND PROPORTIONING OF MATERIALS, AS WELL AS THE DESIGNING OF MARITIME WORKS CAN MINIMIZE THESE DAMAGES. A DETAILED ACCOUNT IS GIVEN OF EXPANSION JOINTS, WHICH ARE THE CAUSE OF MOST OF THE MAINTENANCE WORK THAT HAS TO BE DONE ON SEA WALLS. CONSTRUCTION METHODS BOTH ABOVE AND UNDER WATER ARE PRESENTED, AS WELL AS METHODS FOR REPAIR WORK. IT IS CONCLUDED THAT FUNDAMENTALLY, CONCRETE CONSTRUCTION IN MARITIME WORKS IS SIMILAR TO CONSTRUCTION ON DRY LAND, BUT GREATER CARE HAS TO BE TAKEN, AND MORE ATTENTION PAID TO DETAILS, AT EVERY STAGE OF THE WORK. THE KEY TO SUCCESS IS OFTEN TO BE FOUND IN FOLLOWING THREE MAIN PRINCIPLES: 1. MAKING ALLOWANCE FOR THE INHERENTLY DIFFICULT WORKING CONDITIONS BY PLANNING EVERYTHING IN DETAIL BEFOREHAND AND MAKING SURE THAT THE WORK PROCEEDS AS SMOOTHLY AS POSSIBLE. THIS APPLIES NOT ONLY TO THE CONTRACTOR BUT ALSO TO THE DESIGNER, WHO MUST CONSIDER SEQUENCE AND METHODS OF CONSTRUCTION WHEN THE WORK IS BEING DESIGNED. 2. PAYING PARTICULAR ATTENTION TO THE QUALITY OF MATERIALS AND WORKMANSHIP. 3. PROTECTING THE WORK FROM DAMAGE, AS FAR AS POSSIBLE, DURING THE VULNERABLE PERIOD SOON AFTER IT HAS BEEN CARRIED OUT.
