Abstract:
Concrete ships and bridges incorporating structural lightweight concrete were examined for durability with particular attention given to depth of carbonation. The profile of the carbonation front was determined for these mature structures in or over sea water, and the carbonation front was found not to approach the steel reinforcing even after several decades of exposure. Factors affecting the rate of carbonation are discussed and recommendations are given to limit the extent of carbonation.
