TRB Webinar: Resistivity Measurements in Concrete

TRB conducted a webinar on Wednesday, April 13, 2016 from 2:00-3:30PM ET that detailed the latest advancements in resistivity measurements in concrete. The webinar discussed the status of standard test method development for both bulk and surface resistivity. This webinar also mentioned factors that affect resistivity measurements, as well as examples of implementation of resistivity measurements.

This webinar was organized by the TRB Standing Committees on Durability of Concrete, Properties of Concrete, and Concrete Materials and Placement Techniques. Participants must register in advance of the webinar, and there is a fee for non-TRB Sponsor or non-TRB Sustaining Affiliate employees. A certificate for 1.5 Professional Development Hours (PDHs) will be provided to attendees who register and attend the webinar as an individual.

Learning Objectives
At the end of this webinar, participants were able to:

• Differentiate the difference between bulk and surface resistivity measurements
• Discuss the status of test methods that are under development
• Interpret the results of resistivity measurements in light of influencing factors
