... shrinkage, RDS cracks typically show up after a few weeks. Shrinkage is restrained by coarse aggregate and rebars in the concrete, sub–base friction, and surfaces in contact with the concrete. The restraint reduces the extent of shrinkage but contributes to creation of tensile stress in the concrete...

...-ICDA sub-regions are identified within region, where the pipeline segment is most likely to have experienced internal corrosion damage (based on liquid accumulation and predicted corrosion rate). Modelling is used to identify these locations. Once identified, these locations within the sub-region...

.... Based on these observations, it was determined that the delamination of the epoxy coating system was the result of a weak surface zone of the concrete. Based on our in-house laboratory analysis and the project information provided, we hypothesized that the most likely cause of the concrete sub-surface...

... that the coating system was flawless. The shipyard held that the sub-contracted coatings applicator was responsible for the coating failure. And despite the delamination issues, the shipyard had the contractors re-coat the next generation of ships with the same system. Another year went by, and the client again...
