Abstract:
Describes the specification, supply, control, and construction of three large structures in downtown Melbourne, Australia, using 60 and 65 Mpa (8700 and 9425 psi) concrete. The advantages of high-strength concrete--reduction in member size, thus increasing rentable space; early stripping of formwork; greater stiffness; and reduced axial shortening of compression elements--are discussed, as are cost studies, test programs, supply plants and delivery, materials, mix proportions, placing and compaction, and compression testing and quality control.
