University of Florida researchers, led by principal investigator Kyle Riding, Ph.D., developed a method to measure the tensile stress-strain relationship of ultra-high performance concrete (UHPC). They also developed a specification for material acceptance of field-cast UHPC. Improved specifications and performance verification will allow designers to use UHPC more widely and take advantage of its benefits in Florida transportation construction projects.
