The approach is described which was used to identify suitable mix proportions in a project in Cleveland, Ohio, where the specifications for a project under construction required the production of concrete with a 28-day compressive strength of 12,000 psi. A statistical approach was employed to minimize the time required to obtain meaningful data. The process involved setting up an experimental program to facilitate understanding of the interrelationship between raw materials, admixtures, and specified concrete performance criteria. Statistical models were developed from the data collected and an optimization program built. The program then iterated through thousands of potential concrete mix proportions until combinations with optimal cost-performance ratios were found. The details of the experimental program are described. The findings are presented and the conclusions drawn from the study are discussed.
