THE SIGNIFICANCE OF CONCRETE CUBE TESTS

AN ANALYSIS OF ROUTINE CONCRETE CUBE TESTS PERFORMED UNDER RESEARCH LABORATORY CONDITIONS INDICATED THAT THE OVERALL COEFFICIENT OF VARIATION OF THE PROCESSES OF CUBE MAKING AND TESTING IS ABOUT 3% AND THAT THE COEFFICIENT OF CONCRETE CUBE RESULTS IN REPEATED TESTS OF A SINGLE CEMENT, PERFORMED IN ACCORDANCE WITH THE REQUIREMENTS OF APPENDIX D OF BRITISH STANDARD 12:1928, IS ABOUT 6.5, 4.5 AND 4, AND 3% AT 3, 7, 28 AND 56 DAYS RESPECTIVELY, IN THIS PARTICULAR LABORATORY. THE IMPLICATIONS OF THESE LEVELS OF VARIABILITY OF TEST RESULTS FOR TESTS ON CEMENT CONDUCTED IN ACCORDANCE WITH BS 12, AND FOR THE DESIGN OF EXPERIMENTS IN WHICH CONCRETE STRENGTH IS ONE OF THE PARAMETERS TO BE MEASURED, ARE DISCUSSED. /RRL(A)/
