Abstract:
This month’s Q&A focuses on evaluation and comparison of test results provided by owner’s and concrete producer’s testing agencies. It discusses responsibilities of the owner’s testing agency specified in ACI 301-20 as well as acceptable differences in test results based on interlaboratory studies and precision statements provided in relevant ASTM standards.
