Why We Test Concrete Compressive Strength after 28 Days?
Strength of concrete is generally tested after 28 days as concrete cube strength or concrete cylinder strength The reason for testing concrete strength after 28 days is discussed Why do we test concrete compressive strength after 28 days? Concrete gains strength with time after casting It takes much time for concrete to gain strength [,]
In concrete compression test, normally 150mm x150mm x150mm ,
However, if the designed concrete strength is 100MPa, under the same force (about 2,000kN) supplied by the machine, the stress under a 150mmx150mmx150mm cube is not sufficient to crush the concrete cube Therefore, 100mmx100mmx100mm concrete cubes are used instead to increase the applied stress to crush the concrete cub

Compressive Strength of Concrete -Cube Test, Procedure ,
cube size is 150x150x150, because it has been set as standard size, the value of compressive strength of which has been standardized at 28 daysWe can also use 200mm cube, but you have to convert the compressive strength of 200mm cube to the equivalent of 150mm cube to know the actual strength of the concrete
What is the difference between the cylinder and cube ,
Oct 25, 2017· When you apply compressive stresses on the Cylindrical Specimen in CTM,due to its height ie 300mm,the slender effect causes the cylinder to bear comparatively lesser amount of stress,when compared to a Cube(150mm) causing the cylinder to get crus.
