 HPC was used in the girders of two spans of the Rigolets Pass Bridge. HPC for the Rigolets Pass Bridge Ray Mumphrey and Kian Yap, Louisiana Department of Transportation & Development
High performance concrete with a specified compressive strength of 10,000 psi (69 MPa) and low permeability was used in the girders of two spans of the Rigolets Pass Bridge. This article describes the special provisions for the high performance concrete.

In conjunction with construction of the Rigolets Pass Bridge, the Louisiana Transportation Research Center initiated a research program including material property studies for the high performance concrete used in the girders. Results include compressive strength, modulus of elasticity, creep, and shrinkage. Full Article> Concrete Permeability Testing – Part 1 D. Stephen Lane, Virginia Transportation Research Council
Several test methods exist to measure, directly or indirectly, the penetrability of chloride ions into concrete. Such tests include salt ponding methods and electrical methods for rapid assessment of concrete’s resistance to chloride ion penetration. This article describes and discusses these tests.
