This symposium contains eight papers that were presented at technical sessions sponsored by ACI Committees 544 and 237 at the 2009 ACI Fall Convention in New Orleans, LA. The topics of the papers cover aspects ranging from mixture composition and influence of fibers on the fresh state performance to the connection between fresh state behavior, fiber dispersion and orientation and mechanical properties of the fiber-reinforced composite to full-scale testing and development of prototype applications for structures and infrastructures.
