Publication: Special Publication
Appears on pages(s): 1-26
Keywords: coefficient of variation; compressive strength; concretes; cracking (fracturing); fresh concretes; mix proportioning; quality control; roller compacted concrete; shrinkage; strength; tests; thermal stresses; variability; Design
Abstract:ACI and ASTM standards require an overdesign factor to be added to the design strength to account for variability in the mix. A high variability necessitates an average strength considerably higher than the design strength. There are two key problems wit
