Abstract: In 2011, a new governmental supported research program was started at Nanyang Technological University in Singapore, the objective of which was to develop the technical basis for a future space creation and development of Singapore City based on a large number of sea spaced concrete structures. For such important concrete infrastructures, a highest possible durability, reliability and service life would be of vital importance. As part of the research program, an improved basis for durability design of the concrete structures has already been established. Based on these procedures, a first step of durability design was carried out in order to provide a basis for selecting proper combinations of concrete quality and concrete cover which would give as low probability of corrosion as possible for the required service period of the structures. Concrete mixtures based on combinations of Portland cement, ultra-fine ground granulated blast-furnace slag, undensified silica fume and high-range water reducers appear to be very promising for obtaining proper concrete qualities for the given marine environment. In the present paper, some results from the current research program are briefly outlined and discussed.
