Abstract: The common element in designing durable concrete in aggressive exposures is reducing the rate of ingress by fluids, such as chloride and sulfate solutions. While some tests for measuring chloride diffusion, permeability and rates of absorption have been standardized, due to the extended time required for their completion, they are often only suitable for prequalification of concrete mixtures. For acceptance during construction, rapid index tests are needed. While the ASTM C1202 resistance to chloride penetration test has served this purpose for many years, it can be replaced by even more rapid and less costly test methods such as bulk resistivity and surface resistivity. This contribution will discuss these issues, review alternative test methods, and discuss adoption of test methods in standard specifications.
