Title: Making the Most of Concrete Strength Test Results
Author(s): J. Bruce Tait
Publication: Journal Proceedings
Appears on pages(s): 383-388
Keywords: acceptability; compression tests; concretes; quality control; statistical analysis.
Abstract:There is a risk that concrete proportioned according to ACI 301-72 will produce future strength test results that do not meet acceptance criteria. These risks are discussed in terms of the predictability of the mean strength and standard deviation future concrete production. Reacting appropriately to the mean strength of groups of results as they come to hand is one method of limiting the risk of noncompliance. The main difficulty is generating data quickly enough. Producing concrete from ready-mix plants and on large projects usually encompasses several mix designs. Procedures are proposed to use data from all mixes produced to monitor test results and permit early reaction to trends.
