Title: Minimum Strength Specifications
Can Be Practical
Author(s): William A. Cordon
Publication: Journal Proceedings
Appears on pages(s): 539-544
Keywords: compressive strength; concretes; quality control; specifications; probability theory.
Abstract:Controversy regarding the adequa of concrete structures based on the strength of a concrete cylinder tends to undermine the concrete industry. The owner should have complete assurance that his building is structurally sound. Because of normal variations, the contractor and concrete producer cannot, under common specifications, produce concrete without low strength tests. This paper discusses this problem and shows that the probability of a "minimum strength" can be practical when specifications are realistic and when concrete production is uniform.
