Project description

The main objective of this research project is to design and evaluate the use of fibers in HPC mixes to prevent or reduce early-age cracking in bridge decks. This will be achieved through a systematic investigation supported by laboratory and field tests to ensure that the developed concrete mixes will meet both short- and long-term properties of interest. This project will begin with a comprehensive literature search and survey, which will supplement the knowledge and experience of the research team in working with fiber-reinforced concrete (FRC). A set of HPC mixes, including standard HPC, HPC with fibers, and HPC with fibers and admixtures will then be developed using fibers of different type, geometry, and dosage.
