Ultra-High Performance Concrete

Research focuses on the development and application of ultra-high performance concrete (UHPC), a class of advanced cementitious composites. Investigations explore the fundamental material properties of UHPC, including its enhanced strength, durability, and ductility. Studies involve optimizing mix designs using novel admixtures and supplementary cementitious materials, characterizing material behavior under various loading conditions, and understanding the microstructural evolution that contributes to its superior performance. Research also examines the long-term performance and durability of UHPC in diverse environmental conditions.

This work holds particular relevance for Arkansas's infrastructure needs. The state's extensive transportation network, including numerous bridges and roadways, can benefit from the increased lifespan and reduced maintenance requirements offered by UHPC. Applications in constructing resilient infrastructure capable of withstanding extreme weather events and seismic activity are also explored. Furthermore, the use of UHPC in precast elements and specialized construction projects can contribute to economic development within the state's construction and manufacturing sectors.

This research area draws upon expertise in concrete material properties, cementitious materials research, and structural engineering. Connections are also made to materials characterization, bridge engineering, and additive manufacturing materials. Engagement spans multiple institutions within Arkansas, fostering a collaborative environment for advancing UHPC technology.
