Transfer & Development Lengths in Prestressed Self-Consolidating Concrete Bridge Box & I-Girders

This project contains the following five tasks. Task (1): Design of SCC Mixes This task will focus on defining the design of SCC mixes that will be used in the project. The PI will contact large number of Illinois precasters who are working on the development of SCC to obtain detailed information on the type and design of their SCC mixes as well as the type and size of precast elements they produce. Task (2): Conducting SCC Qualifying Tests The SCC mixes identified in the previous task will be subjected to wide range of tests (J-ring, L-box, etc.) to examine its plasticity and physical properties and compare it with typical properties of SCC. Concrete cylinders will also be cast and tested at various ages to specify the mechanical properties of the SCC mixes. Task (3): Conducting Pull-Out Tests The SCC mixes that was selected in Task (1) and passed the qualifying tests in Task (2) will be used in conducting a series of pull-out tests. The primary aim of these tests is to evaluate the bond strength between the concrete and prestressing strands. Concrete blocks (24in-wide x 36in-length x 24in-depth) will be used in these tests. Task (4): Casting of Girders and Measuring the Transfer Length Based on the pull-out test results, two SCC mixes will be recommended and selected to be used in casting the girders. Two types of girders will be involved in this project. The first type is the 27''x48'' bridge deck box girders with void, while the second type is the 42'' I-girders. The transfer length of four full-scale girders will be measured during this task. Task (5): Conducting Flexural Tests During this task, the precast girders will be transported by the precaster to the Newmark Structural Engineering Laboratory (NSEL) at the University of Illinois at Urbana-Champaign where the flexural tests will take place.
