### cubic strength to cylinder strength Structural

Oct 01 2017 In actual structures in the field the casting and loading are similar to those of the cylinder and not like the cube Shetty 2005 The comparison between the compressive strength of cube and compressive strength of cylinder a factor of 08 to the cube strength is often applied for normal strength concrete AlSahawneh 2013 Cube compressive strength is approximately 15 more than the cylinder compressive strength Concept This difference in compressive strength occurs because in the cylinder less end restraint and more uniform distribution of stress over the crosssection exist due to which the cylinder strength is probably closer to the true uniaxial

### What is the difference between cube and cylinder strength

For normal concrete and HSC the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens 6 As states in BS 1881 the compressive strength of concrete gained by cylinder specimens is equal to 08 times of the compressive strength gained by cube specimens Using cube tests in lieu of cylinder tests Q Can ASTM C109 cube tests be used in lieu of ASTM C39 cylinder tests A Mortar cube tests ASTM C109 could be a good indicator of potential strength but they should not be the sole basis for evaluating concrete strength To meet ACI 318 requirements concrete tests should be run on trial batches of concrete made with proposed aggregates
