Towards Standardization of a Rapid Chloride Conduction Test for Concrete



The paper describes the development and standardization of a rapid chloride conduction test for concrete. The test has a sound theoretical basis, is rapid, efficient and simple to perform, and is of low cost. Results are given which show that vacuum saturation is a suitable procedure to pre-saturate samples with a 5 M sodium chloride solution, for standard sample sizes and “normal” concretes. A ruggedness test was conducted to determine the degree to which the conditions specified in the test method must be controlled. Results show that the test is sufficiently rugged to accommodate small changes in the operating conditions, and that it is possible to achieve consistent results. The paper also reviews the standard test method. Precision for the test is best characterized by the coefficient of variation, which typically is less than 7% for a set of results from properly conducted tests.
