Development of an Innovative Bio-Mediated Self-Healing Concrete Technology

Cracks in concrete structures significantly compromise their durability. For example, cracks are commonly observed in bridge decks at different stages of service, due to early age volume shrinkage, or long-term service loads, and climate conditions such as dry-wet cycles and freeze-thaw cycles.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 233: Development of an Innovative Bio-Mediated Self-Healing Concrete Technology aims to conduct a proof-of-concept investigation towards developing an innovative fungi-mediated self-healing concrete technology.
