Compressive strength prediction of high

Abstract In structural engineering, concrete compressive strength (CCS) is the most important performance parameter for designing the conventional concrete and high-performance concrete (HPC) structures. The precise prediction of this parameter becomes more crucial when considering this parameter for cost-benefits analysis and time point of view.

High-Strength Concrete. In the early 1970s, experts predicted that the practical limit of ready-mixed concrete would be unlikely to exceed a compressive strength greater than 11,000 pounds square inch (psi). Over the past two decades, the development of high-strength concrete has enabled builders to easily meet and surpass this estimate.
