A work in English, the logical choice for this task, had been contemplated as Stahlbetonbrucken was still in its earliest stages of preparation. The main objective of the early portion of the project was to determine whether high-strength high-performance lightweight concrete mix designs could be developed with f ‘ c = 6000 psi and f c = 8000 psi for use in prestressed concrete girders.
