Title: Uniformity Of Concrete On The Average Job-A Study Of 13,000 Field Tests
Author(s): Hugh C. Ross
Publication: Journal Proceedings
Appears on pages(s): 277-284
Abstract:An analysis is presented of 13,000 concrete compression tests from 60 different job operations. The data show what variations in strength are likely to be encountered on the average job and the extent to which these variations are affected by the class of concrete involved. Curves illustrate how overdesigning will reduce the number of substandard tests and what margin of strength should be provided to meet given quality requirements.
