However, the few elements that were replaced, in about 1968 and in 1993, have nearly all resulted in severe longitudinal cracking and extensive reinforcement corrosion, despite the later concretes being superficially of better quality than the original 1943 concrete. This paper will report statistics for maximum crack width for each of the three concrete populations, based on measurements made in 2004 and in 2006, as well as in-situ and laboratory measurements that indicate the 1943 concrete shows contradictory properties, having both high permeability and high electrical resistivity. Also, the 1943 and 1993 concretes were found to have similar chloride profiles and similar chloride concentrations at the reinforcement bars, which, again, is inconsistent with the 1943 elements showing much less reinforcement corrosion than their later replacements. These observations, and some other un-reported cases in the literature, cast doubt on the conventional notion that durable reinforced concrete structures requires reduced concrete permeability, denser concretes or greater cover.]]> Wed 11 Apr 2018 11:47:12 AEST ]]> Observations and analysis of a 63-year-old reinforced concrete promenade railing exposed to the North Sea https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:7120 Wed 11 Apr 2018 11:33:26 AEST ]]> Time to initiation of reinforcement corrosion in marine environments: a review of older concrete structures https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9065 Wed 11 Apr 2018 09:53:19 AEST ]]> Time-dependent reliability analysis of corrosion-induced concrete cracking https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:339 Tue 11 Jun 2019 11:56:48 AEST ]]> Reinforcement corrosion in concrete exposed to the North Sea for more than 60 years https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:8070 Sat 24 Mar 2018 08:34:26 AEDT ]]> Probabilistic modeling of structural deterioration of reinforced concrete beams under saline environment corrosion https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5350 Sat 24 Mar 2018 07:43:52 AEDT ]]>
