Abstract:Presents and discusses a statistical experimental design technique used in developing high-strength concrete using locally available materials in the Cleveland area. The technique resulted in evaluating only 33 mixtures to study the effects of five variables on compressive strength and modulus of elasticity. A total of 243 mixtures would have been required using normal methods. The data were analyzed statistically using regression-analysis techniques, and the models obtained were then used to provide information on the experimental region defined by the original 243 mixtures. The data presented indicate that the highest compressive strengths were obtained with a 50:50 blend of limestone and silica gravel, whereas the highest average elastic moduli were obtained with mixtures containing 100 percent silica gravel.
