Using cube tests in lieu of cylinder tests

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 ...

Crushing Concrete Cube or Cylinder at 28 days

Apr 01, 2018  The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved
