Significant advances have been made in our understanding
of the influence of concrete mixture constituents
on the likelihood and rate of reinforcement
corrosion. Much of this work has focused at understanding
the role of cement extenders and admixtures
in modifying the ionic and fluid transport properties
of the concretes that we use in chloride-laden environments.
Greater understanding of the notion of the
‘threshold’ level of chloride content in relation to the
binder type has also helped to clarify much of the
complexity of empirical data.
