Topic: Transforming Mine Tailings into Sustainable Construction Materials on 10/23

Abstract: Mine tailings (MTs), the finely ground residues from mineral processing, pose major environmental and safety challenges. This talk explores innovative strategies to transform these abundant waste materials into sustainable construction products. By characterizing the physical and chemical properties of MTs, we develop technologies to produce geopolymer bricks, lightweight aggregates, and ceramics that meet engineering performance standards while reducing carbon footprint. This approach supports a circular economy by minimizing tailings storage, conserving natural resources, and offering cost-effective alternatives for the construction industry. The seminar will provide insights into the feasibility, performance, and broader environmental impact of mine-tailings-derived materials.

Speaker: Dr. Reza Hedayat is an Associate Professor in the Department of Civil and Environmental Engineering at the Colorado School of Mines. He received his Ph.D. in Civil Engineering from Purdue University. Dr. Hedayat's research interests focus on non-destructive evaluation of materials and structures, multi-scale studies of geomaterials, and sustainable construction materials. Dr. Hedayat is the recipient of the Early Career Award from the US Department of Energy, Cook Ph.D. Dissertation award from the American Rock Mechanics Association (ARMA) and the Manuel Rocha Medal Runner-Up Award from the International Society of Rock Mechanics (ISRM).
