TL;DR: In this article, the chloride ion transport and binding capacity of different concrete samples located in marine atmosphere zone, splash zone, tidal zone and submerged zone for 9 and 13 months were tested.
TL;DR: In this article, the authors describe the corrosion loss profiles of 1-m long vertical steel strips attached to a raft and exposed for 1 year in calm natural seawater on the Australian eastern seaboard.
TL;DR: In this article, the effects of exposure conditions (atmospheric, tidal and splash zones) on chloride ingress into concrete and time-dependent chloride diffusivity of concrete were investigated by field investigation.
TL;DR: In this article, a corrosion survey of a 24-year-old reinforced concrete jetty structure in Woodlands, in the northern part of Singapore, has been conducted, where the principal test methods used in the survey were chloride profile analysis and corrosion potential mapping.
Abstract: A corrosion survey was made of a 24-year-old reinforced concrete jetty structure in Woodlands, in the northern part of Singapore. This particular jetty structure was selected for the field survey since it was already showing signs of reinforcement corrosion and deterioration. Two piles which were located near the stairs (and were easily accessible) were surveyed in detail. The survey covered the mean tidal zone, the upper tidal zone at 0·8 m above the mean tide level, and the splash zone at 1·3m above the mean tide level. The principal test methods used in the survey were chloride profile analysis and corrosion potential mapping. A general visual and de lamination survey was also carried out. The chloride content in the concrete increased with height above the mean tide level. Chloride diffusion coefficient values, which were calculated from the chloride profile measurmounts, ranged from 2·13 × 10-8 cm2/s athe mean tidal zone to 5·50 × 10 8 cm2/s at the splash zone. The upper tidal and splash zones, i.e. ...
TL;DR: In this paper, six corrosion protection systems for offshore wind power constructions have been subjected to offshore conditions on a test site in the North Sea in three different exposure zones, namely splash zone, intermediate zone, and underwater zone.
