ABSTRACT

Owing to the important role of chloride ingress in concrete with regard to the durability of concrete structures, many methods have been proposed for testing such chloride ingress. However, as described in Chapter 2, the complexity of the process has, until now, hindered the reaching of a general agreement on a single test method for standardisation. Castellote and Andrade (2006) through an international network, RILEM TC 178-TMC Testing and Modelling Chloride Penetration in Concrete, collated details of various laboratory test methods, most of which were reviewed by Nanukuttan (2007). These methods can be categorised in different ways according to the test principles, e.g. diffusion or migration, steady-state or non-steadystate, conventional or accelerated, or laboratory or field applicable. Some commonly used test methods are reviewed in the following sections.
