Revisiting Effects of Cylinder Cap Type and Eccentricity— Part II: Failure Mode and End Conditions

Part I of this paper analyzed compressive strength results from one hundred 6 x 12 in. (152 x 304 mm) cylinders cast from a single batch of ready mixed concrete, tested with both bonded and unbonded cylinder caps, concluding that while either cap type produced approximately equivalent strength, there was a significant difference in the standard deviations of the two populations. Further, strength obtained with unbonded caps was less sensitive to variations in cylinder eccentricity during testing. Part II continues with the observations that predominant failure modes differed with cap type and eccentricity. There is some evidence of connection between the end condition or flatness of the cylinders and failure mode.
