Description

To obtain improved durability, designers are specifying limits for ASTM C1202, “Standard Test Method for Electrical Indication of Concrete’s Ability to Resist Chloride Ion Penetration” or, more recently, electrical resistivity test methods. The objective of this session is to discuss the different electrical methods and appropriate test limits. In addition, errors in test results related to differences in specimen geometry and differences in pore fluid conductivity will be discussed, as well as the use of the formation factor to correct for these errors. The use of electrical methods to predict diffusion coefficients and service life are also presented.

Learning Objectives

1. Identify modeling approaches than can derive chloride diffusion to help predict chloride egress in tested hardened concrete

2. Describe different factors that affect resistivity tests of concrete that is used to predict chloride diffusion and chloride penetration

3. Explain the formation factor and how it is related to the pore structure and pore conductivity of concrete

4. Explain advantages of bulk resistivity tests on concrete core samples for fluid penetration resistance and factors that could negatively affect accurate results of the test.
