Rating Concrete Permeability Based on Resistivity Measurements

The AASHTO T 277/ASTM C 1202, Electrical Indication of Concrete Ability to Resist Chloride Ion Penetration, has been widely accepted for assessing durability of concrete. The test provides an indication of the concrete’s ability to resist chloride ion penetration but it has many shortcomings: it is slow and time consuming, destructive, prone to errors caused by sample heating, and fails to adequately capture features associated with supplementary cementitious materials (SCMs). Electrical resistivity measurements (AASHTO T 358, Standard Method of Test for Surface Resistivity Indication of Concrete’s Ability to Resist Chloride Ion Penetration) have the potential of providing performance-based evaluation of concrete although they may not always yield accurate results. However, the data obtained from these measurements do not relate to concrete water permeability. It is suggested that a formation factor that incorporates the ratio of the resistivity (ñ) of the bulk concrete to the resistivity (ño) of the pore solution or other approaches can be used to provide a better assessment of transport properties. There is need to evaluate the feasibility of using this or other approaches as a tool for rating concrete permeability based on resistivity measurements. The objective of this research is to develop recommendations for rating concrete water permeability based on electrical resistivity measurements.
