Transportation and Infrastructure

Co-lead organizers: John Provis (john.provis@psi.ch, Paul Scherrer Institut, Switzerland) and Jeff Bullard (jwbullard@tamu.edu, Texas A&M, U.S.)

Abstract: Transportation and infrastructure activities take an enormous share of human labor, energy consumption, and environmental impact around the world. Global construction accounts for 30% of the world’s energy demand and costs about US$7 trillion each year, US$1.4 trillion of which comes from bridges, highways, and roads. Supporting all this activity is a global cement market worth about US$340 billion annually. New cementitious materials and additives are being explored that can enable new construction methods, prolong service life, decrease embodied energy, and reduce the impact of infrastructure materials on the environment. This symposium will provide a forum for communicating the latest advances in cementitious materials for transportation and infrastructure. Contributions are encouraged that highlight enabling chemistries, processing methods, models, and applications in the seven sessions listed below.

Proposed sessions:

• Low-carbon infrastructure materials
• Additive construction materials and methods
• Geopolymer chemistry and processing
• Computational modeling and artificial intelligence for materials discovery and optimization
• Understanding and controlling material degradation
• Repair and retrofit materials for infrastructure and transportation
• Novel materials and additives for sustainable infrastructure
