Abstract:
Approximately 85,000 yd3 of cast-in-place concrete, of which 21,000 yd3 were 10,000 psi concrete, were used to complete a 72-story building in Dallas, Tex. High-strength concrete was considered for this project because it met the architectural, engineering, and economic demands of the tall, slender structure. The data reported are results of extensive testing prior to the start of constrution. Evaluation of strength tests of field samples of concrete also are reported to show that quality-control techniques used for low to moderate strength concretes may not be appropriate for higher strength concretes.
