The Center for Infrastructure Renewal at Texas A&M University held a webinar earlier this month titled Future of Emerging SCMs. It featured a presentation by Anol Mukhopadhyay on durability-based concrete mix design followed by a panel discussion with NRMCA's Karthik Obla, Ivan Diaz, Lisa Lukefahr and Anol Mukhopadhyay on the current fly ash shortage. The panel discussed the current problem and potential solutions such as changes needed in the industry standards and specifications to reduce landfilling of fly ash produced, harvesting fly ash, other supplementary cementitious materials such as slag cement, silica fume, natural pozzolans and ground glass pozzolans, flexible concrete specifications in light of supply constraints and a performance-based approach toward concrete specifications.
