From page 1...
... TFHRC labs are among the few in the United States with the tools to conduct large-scale concrete structural testing and to characterize materials. S.1  Evaluation Approach The evaluation focused primarily on the impacts of UHPC-C compared with conventional concrete connections (CC-C)

... To estimate national benefits, net benefits were expressed in dollars per square foot of bridge and then scaled to the aggregate square footage of existing and potential future bridge projects that use UHPC-C. The proportion of these benefits attributable to TFHRC activities was compared with TFHRC UHPC-C research costs to determine the national-level return on TFHRC investment.

From page 3...
... Interviews with industry stakeholders indicated that TFHRC research and outreach activities offered high value and greatly influenced the adoption of UHPC-C in the United States. A high percentage of the benefits could be attributed to TFHRC initiatives to pro­mote UHPC-C use: most respondents attributed virtually all U.S.

From page 4...
... Net benefits of using UHPC versus conventional concrete may vary on the basis of the quantity of material needed and the expected performance benefits for each application. S.4  Significance and Promoting Adoption Stakeholder interviews indicated strong agreement that TFHRC's UHPC-C technology transfer efforts are highly effective.

From page 5...
... The key remaining barriers to adoption of UHPC-C are the high costs of the material itself and of the needed equipment and labor required to apply the material. Interviewees suggested that additional TFHRC standards for producing and testing generic UHPC mixes could help decrease materials costs.
