[This study aims to investigate the thermal
behavior of concrete influenced by chloride and corrosion of reinforcing steel. The results
of this thermal behavior are useful for determining the detectability of corrosion by
thermograph. Different mix proportions of concrete and level of corrosion were studied.
The results of temperature profiles obtained from experimental work proved that when
there is presence of dense rust confined between concrete and steel, thermal behavior of
concrete around steel bar changed. When applying heat source on top surface of the
specimen, there was a slight change of temperature on top of corroded bar while there was
more signification change of temperature below it. /quote]

describes the general nature of reinforcement corrosion INCLUDING carbonation which I mentioned earlier, and dissimilar metal galvanic effects..
The statement that chloride attack is the major cause of premature reinforcement failing does NOT make it the global, universal issue that the OP is pushing....I still stand by my statement that chloride attack does not apply to the vast majority of structures, and that proper design resolves most issues.
Google fail....
