  • Research Objective
    Objectives are to: 1) Develop an economical and practical UHPC mix that has a target compressive strength of 18 ksi and performance characteristics superior to those of the mixes currently used in Nebraska. 2) Investigate the use of the NU UHPC mix in developing an optimized section for prestressed bridge girders using the forms that are readily available to precast producers in Nebraska.
    Abstract
    The general objective of this research is to promote the use of UHPC in the construction of precast prestressed bridge girders in Nebraska. The specific objectives are to: 1) Develop an economical and practical UHPC mix that has a target compressive strength of 18 ksi and performance characteristics superior to those of the mixes currently used in Nebraska. 2) Investigate the use of the NU UHPC mix in developing an optimized section for prestressed bridge girders using the forms that are readily available to precast producers in Nebraska.
