In the prestressed, precast concrete industry high-strength concretes are widely used for axially loaded piles and columns, but also increasingly for flexural members such as double tee beams and girders. Use of high-strength concretes permits fabrication of longer, more slender spans and economic mild and prestressed reinforcing steel patterns. And, for plant-produced members the necessary high strength may be achieved easily and consistently without out-of-the-ordinary quality control procedures9 and this is documented here. To facilitate designs using high-strength concretes a number of design aids have been developed, and selected examples are persented. Finally, by its very nature, where high early strengths are required prestressed precast concrete members frequently have a substantial amount of long-term reserve capacity and excellent deflection control.
