### Different between cube and cylinder in concrete compressive test - INTERPRETATION OF COMPRESSIVE STRENGTH IN …

Answer (1 of 6): There are two basic reasons why cube strength is more than cylinder strength: 1. Width to depth ratio of cube is 1:1 while that for cylinder is 1:2 hence confinement is more for cube than cylinder. 2. The circular shape …From my own experience and experimentation, I found the cube/cylinder strength ratio decreases by the increase in concrete strength. A ratio of 1.15 to 1.25 is expected for normal concrete (25 to ...

### UHPC Compressive Strength Test Specimens: Cylinder or Cube? - WHY COMPRESSIVE STRENGTH OF CONCRETE CUBE IS GREATER …

Answer (1 of 5): When a specimen is placed on the compression testing machine it tends to expand in the lateral direction according to its poisons ratio. The plates of the machine restrict the expansion of the material near the the plates, that …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 ...

### compressive strength test of cube vs cylinder/why we used - YouTube - Why cube strength is greater than cylindrical? - Quora

sight of the object of making and testing concrete cubes. For instance, in much mass concrete work, the criterion is durability rather than compressive strength. Other things being equal, both are related to the water/cement ratio and, if we really knew what the water/cement ratio was all the time, only occasional concrete cubes might beThis investigation assessed the effect of compressive strength and curing age of concrete on the Cylinder– Cube Strength Relationship (CCSR) of South African Concretes. Cubes and cylinders were cast for 7, 28 and 56 day curing ages from 36 concrete mixes varying in strength, aggregate type and cement type.
