Abstract:
The method used at present for interpreting concrete strength data (ACI 318-63, Section 504 ) is briefly examined, attention being restricted to the case where strength is a basis for acceptance, and where mix proportioning, quality control, job inspection, etc., are consistent with accepted good practice. The present method focuses on the proportion of understrength test outcomes. A generalization of this method, using the same underlying assumptions, yields a probability function on the proportion of understrength concrete in the work, which is the variable of real interest. This probability function provides a basis for rational decisions regarding acceptance of the work.
