摘要：	Ultra-high-performance concrete (UHPC) is a material with significantly different properties from conve tional concrete. By taking advantage of this material's increased compressive strength, durability, tensile strength, and postcracking capacity from fiber forcement, bridges may be designed with longer spans, slimmer members, and increased design lives.UHPC mixture proportions were developed with materials available primarily within the state of New Mexico. To familiarize the local concrete industry with this concrete, the batching, casting, and curing of four trial batches were conducted with local pre-casters to evaluate production methods and develop recommendations and procedures for the batching of this UHPC. The trial batches were conducted to evaluate the plant and production capabilities for the effective batching of the locally produced concrete. Successful completion of the project demonstrates that this UHPC can be produced by adapting laboratory methods for plant production with no changes to plant facilities.
