STUDY OF COMPRESSIVE STRENGTHS OF PORTLAND CEMENT CONCRETE TEST CYLINDERS

CONCRETE COMPRESSIVE STRENGTH DATA FROM BRIDGE PROJECTS COVERING A 2-YEAR PERIOD WERE COMPILED AND COMPUTER PROCESSED IN A STUDY ATTEMPTING TO VERIFY SUSPECTED VARIATIONS IN STRENGTH, AND TO RELATE STRENGTHS TO POSSIBLE CAUSES OF VARIATIONS. CONCRETE STRENGTHS FOR 1966 WERE FOUND TO BE SIGNIFICANTLY HIGHER THAN THOSE FOR 1965 FOR THE SAME TYPE OF MIX. CORRELATIONS WERE ALSO CALCULATED COMPARING CYLINDER STRENGTH WITH SUCH VARIABLES AS WATER, SLUMP, AIR CONTENT, AND THE FINENESS MODULUS OF THE FINE AGGREGATE. /AUTHOR/
