Durability and Volumetric Stability of Non-Proprietary Ultra-High-Performance Concrete Mixes Batched with Locally Sourced Materials

Ultra-high-performance concrete (UHPC) is distinguished by its superior mechanical and durability properties. These characteristics are attained through a precise mixture design that includes a low water-to-cement ratio, high fineness supplementary cementitious materials (SCMs), and steel fibers. This report presents the evaluation of durability and volume stability properties of a non-proprietary UHPC mixture using locally sourced materials in Utah. This study uses response surface methodology and central composite design to optimize the UHPC mixture. The optimized UHPC mixture with 2% steel fiber by volume achieves 22,113 psi (153 MPa) compressive strength. The freeze-thaw durability test shows minimal degradation, with the retained dynamic modulus of elasticity of over 99.1% after 90 cycles. Compared with similar studies, UHPC specimens are expected to degrade less than the Utah Department of Transportation (UDOT) specified limit of 96% after 600 cycles. The average electrical resistivity of the UHPC specimens is 192 kΩ-cm, which indicates very low chloride-ion penetration. The volume stability test results demonstrate impressive performance as well. The drying and autogenous shrinkage strain of the mixture after 80 days are 365 and 225 microstrain, respectively. Thus, the drying shrinkage strain is about half of the UDOT acceptable limit of 766 microstrain. Overall, the developed locally sourced UHPC mix evaluated in this project exhibits excellent mechanical, durability, and volume stability properties. This research project contributes to improve the accessibility and affordability of the material for the widespread use in infrastructures projects to ensure the longevity and reliability of transportation infrastructure.
