STRUCTURAL PERFORMANCE OF SELF-CONSOLIDATING

precast, prestressed girders. Six test girders were subjected to transfer length and flexural testing. Three separate concrete mixtures, two girders per mixture, were used to construct these specimens. One mixture was a moderate-strength, conventional-slump concrete mixture, similar to the concrete used in typical ALDOT girders, with a

Flexural Behavior of High-Early-Strength Self

A research program investigated the application of high-early-strength self-consolidating concrete (SCC) for precast, prestressed bridge girders. The SCC and conventional concrete (CC) in mixtures had a target 16-h release strength of 34 MPa (5,000 psi). Testing was performed to evaluate the flexural response and bond performance of the girders.

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3-5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.
