One of the many factors that contribute to concrete durability is the material’s resistivity. Higher resistivity indicate a material is a poor conductor of electric currents. How does this affect the longevity of our roads and other concrete infrastructures? TRB will host a webinar on Tuesday, October 11, 2022 from 12:30 PM to 2:00 PM Eastern that will discuss concrete resistivity and its impact on durability. Presenters will share a state agency perspective, new research, and potential impacts for practitioners. 

This webinar is sponsored by the TRB Standing Technical Committee on Durability of Concrete.

Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100. Sign into to view registration information. Contact Patrice Davenport to inquire about becoming a TRB sponsor or global affiliate organization.

A recording will be sent to all registrants after the webinar.
