Self-Consolidating Concrete (SCC) has high potential prestressed bridge construction in Wisconsin, but there is a lack of definitive data on its material properties for WisDOT. The primary objective of the work proposed herein is to develop a Wisconsin specific mix design and its specification for the use of SCC in prestressed girders used on WisDOT bridge projects. To accomplish this objective, this project will test several SCC samples for examining the following characteristics: 1) Material Properties, 2) Time-Dependent Characteristics, and 3) Prestress Losses. This project will not only help in better understanding the material properties of prestressed SCC girders, but will also provide recommendations related to its design and guidance that can be useful for a full-scale implementation on one of the department's bridge projects. This implementation will be coordinated with WisDOT Bureau of Structures and a Precast Girder Producer for the design, implementation, testing, monitoring and documentation. Field monitoring-based structural evaluation process will also be included to evaluate the structural performance of a test prestressed SCC bridge girder on the project.
