A site-based study of durability indexes for concrete in marine conditions
This dissertation comprises a site-based investigation into the ease at which durable concrete can be produced, using three extenders and four site-curing methods over four seasons in the Port of East London (Eastern Cape). GGBS, FA and CSF were selected as extenders as it is well established that these extenders enhance the durability properties of concrete, relative to plain unblended concretes. The test elements modelled two structural elements in the Port viz. a reinforced concrete retaining wall and mass concrete paving slabs. This was to facilitate possible future correlation or further study. For closer correlation, test elements were cast in close proximity of the actual retaining wall and likewise for the slabs.
