Develop a Cost Efficient and Effective Method for Cast-In-Place Ultra High Performance Concrete (UHPC)

Fiber Reinforced Ultra High Performance Concrete (FRUHPC) offers enormous advantages to the United States as an advanced material to revitalize the nation"s infrastructure and in the building of new infrastructure that is sustainable, cost-effective and long lasting. In addition, the material has applications in defense of the nation that must be exploited. Adoption of UHPC in the U.S. has been slow and suffers from various logistical and economic headwinds. The proposers intend to investigate the methods of achieving high compressive strength and post-cracking hardening concrete and extend those methods into field applications where successful, laboratory-quality large cast-in-place pours can be made with optimized equipment on military and civil projects. Packing density optimization, sequenced high-shear on-site mixing, self-compacting and good flow-ability characteristics and protected curing methods will be the main focus of the work.
