Ultra-High Performance Concrete Reinforced with Multi-Scale Hybrid Fibers and its Durability-Related Properties

MassDOT is seeking to improve the quality and durability of fiber-reinforced concrete (FRC) and ultra-high performance concrete (UHPC) for longevity and constructability of new structures and repair of existing structures. There exist critical gaps in understanding the efficiency of mixture design and fibers on concrete performance, especially the mechanical and durability-related properties. A better understanding of FRC and UHPC will promote the development and applications of high-quality concrete to satisfy the performance expectation of future transportation infrastructure. The overall research objective of this project is to develop novel, non-proprietary, FRC and UHPC mixtures to identify and maximize the roles of fibers and additives in enhancing mechanical and durability-related properties, and to promote the widespread use of FRC and UHPC in transportation infrastructure. The project includes seven primary research tasks including literature review, development of a qualified construction materials list, optimization of mixture design, physical, mechanical, and durability-related property evaluations, large scale batching, mockup and field tests to investigate merits and barriers impacting successful applications of FRC and UHPC in the transportation infrastructure. This project will benefit the Standard Specification Development for construction materials by improving quality and extending service life of critical infrastructure related to public safety.
