Compliance requirements for compressive strength of concrete

The compliance requirements for the compressive strength of concrete, as provided in Australian Code AS 3600 - 1988, are examined. The implications of each rule for the production and project assessment are analysed by the operating characteristic curves generated by analytical methods and verified by Monte Carlo simulation technique. The paper critically examines the drawback of some of the rules provided in the code. With the existing rules, an anomalous situation arises where the risk of accepting substandard concrete becomes higher as more samples than the minimum required are used in the test. Also the acceptance rules for the limited production grade need to be revised so that the operating characteristic curve does not fall into the unsafe region in the normal probability graph. There seems to be a need to review some of the acceptance criteria to make them more equitable and efficient. Suggestions for improvement are also discussed.
