Prestressed Concrete Design - SlideShare

Jan 10, 2016 · Introduction 1.1 Background The idea of prestressed concrete has been around since the latter decades of the 19th century, but its use was limited by the quality of the materials at the time. It took until the 1920s and '30s for its materials development to progress to a level where prestressed concrete could be used with confidence.

Designing and Proportioning Normal Concrete Mixtures

and shape of the concrete member to be cast, the amount and distribution of reinforcing steel in the member, and the thickness of slabs. Grading also influences the work-ability and placeability of the concrete. Sometimes mid-sized aggregate, around the 9.5 mm (3⁄ 8 in.) size, is lacking in an aggregate supply; this can result in a concrete
