Denso void filler aids corrosion prevention at Aberdeen Harbour

摘要

Aberdeen Harbour Board has recently completed the redevelopment of shipping berths at Torry Quay to meet the requirements of larger supply ships for the North Sea oilfields. The main contractor was McLaughlin & Harvey from Belfast. An integral part of the quay construction is formed by 10 m horizontal tie-bars which are cast into a structural concrete slab located 4 m below the finished surface. The bars protrude through the main quay wall formed by sheet piles and act as a fundamental component of the structure, thus requiring protection from the harshest marine conditions. In order to deter corrosion and help elongate the structures life span it was a design requirement to conceal the exposed ends within steel cylinder caps and provide an anti-corrosion void filler compatible with the cathodic protection system.
