Cylinder or Cube: Compression Strength Testing of 12 to 30 ksi Concrete

Accurate determination of the compressive strength of very high strength concretes is currently a difficult proposition due to large testing machine capacity requirements and the need for cylinder end preparation. An experimental program is being conducted to determine whether alternate specimen types can be reliably used to determine the compressive strength of an ultra-high performance concrete in the strength range from 12 to 30 ksi. 2 in., 3 in., and 4 in. cylinders were tested alongside 2 in., 2.78 in., and 4 in. cube specimens. Preliminary results have demonstrated that the 3 in. cylinder as well as the 2.78 in. and the 4 in. cubes were found to be acceptable alternatives to the standard 4 in. cylinder specimen. The 2.78 in. cube specimen results to date have indicated that it can provide acceptable results for situations where cylinder end preparation and machine capacity are concerns.
