Not all concrete is created equally. Lightweight concrete (LWC) is a feasible rehabilitation technique for many structures, including bridges and high-rises. TRB hosted a webinar on Monday April 12, 2021 from 1:00 to 2:30 PM Eastern that discussed the current usage and demand of LWC in the United States.
