Title: How Good is Good Enough-A Dilemma in
Acceptance Testing of Concrete
Author(s): H. W. Chung
Publication: Journal Proceedings
Appears on pages(s): 374-380
Keywords: acceptability; building codes; compressive strength: concretes; mix proportioning; quality control.
Abstract:Compliance with concrete strength level requirements is usually judged by an acceptance test. The criteria of acceptance stipulated in ACI 3 18- 71, as well as the British and Australian codes, are reviewed and their efficiencies are compared by means of the operating characteristic curves. It is shown that the ACI 3 18-71 criteria involve a low producer’s risk but a very high consumer’s risk, with the effect that "good" concrete is always accepted but "poor" concrete may not be detected. A revision of the criteria is proposed whereby the risk is distributed more evenly between the two parties.
