Presentation Description:
This presentation provides a summary of three technologies that are being developed at Penn State with the goal of producing low-CO2 concretes that meet relevant performance requirements. First is an artificial intelligence (AI) tool that assists with mixture proportioning of low-carbon concrete to achieve a target 28-day strength while minimizing the cost and CO2 footprint. The AI tool uses the characteristics of Portland cement and pozzolan (SCM) available to a producer and provides an optimized mix design. The second technology produces self-consolidating high-volume fly ash concrete for precast applications. Such concretes have a minimum 40% fly ash by mass of cementitious materials and must achieve 3500 psi strength at 24 hours to allow form removal and prestressing. The third technology is a collaboration with University of Wisconsin and targets producing carbon negative concrete. It uses direct air capture of CO2 to sequester carbon in concrete ingredients (aggregates and cementitious materials) which are subsequently used to produce geopolymer concrete without using Portland cement.
About The Presenter:
Presenter Bio: Dr. Farshad Rajabipour is a Chaired Professor and the Interim Head of the Department of Civil and Environmental Engineering at Penn State University. He is also the Director of USDOT’s CIAMTIS university transportation center (https://r3utc.psu.edu/), which is focused on Improving the Durability and Extending the Life of Transportation Infrastructure. He received his Ph.D. from Purdue University in Civil Engineering with emphasis on cementitious materials. He has 22 years of teaching and research experience in support of sustainable concrete materials that are used in buildings and other civil infrastructure. Specifically, he performs research on concrete decarbonization, unconventional pozzolans, concrete durability, and ultra-high-performance concrete. He is a fellow of the American Concrete Institute (ACI) and the Cementitious Materials Section Editor for ASCE Journal of Materials in Civil Engineering. REGISTER: https://nccaci.org/event-5568901
