Abstract:The scope of the study was to make concrete mixes in the laboratory using a partial factorial, with three cement contents, two coarse aggregates and three fine-to-coarse aggregate ratios. The mixes showing the best properties and highest compressive strengths were repeated for several test repititions to determine if these strengths could be obtained consistently. The concrete using limestone did consistently make the high strengths, while concrete using pea gravel did not consistently make the high strengths.
