COMPRESSION TESTING OF CONCRETE: CYLINDERS VS.

The main difference between cylinder and cube testing procedures is capping. Cylinder ends are usually not plane or parallel enough to mate properly with platens of compression testing machines, and thus must be capped with sulphur, neoprene, or other suitable material for proper distribution of the applied load.
