Whats the difference between a cube and a cylinder?

There is not much difference between a cube and a cylinder. The cube is a 3d square and a cylinder is actually 3d circle in a rectangle form.

Different between cube and cylinder in concrete compressive test?

The difference in compressive strength is due to the difference between the modulus of elasticity of concrete and that of the steel which is used to apply the compressive force on the concrete. The pressure applies a lateral confinement pressure which is equal to d/3 meaning that for the cylinder, 2d/3 is confined leaving d/3 unconfined whereas for the cylinder 2d/3 is confined means all of the cube is confined. This leads to the cube having a higher compressive strength that the cylinder. For more information, try to read about the triaxial test and the effect of confinement on the compressive strength of soil samples.

How do you convert cylinder strength to cube strength?

With regards to concrete strength, a cylinder test strength is usually between 5 and 25 percent less than a cube test strength. You can also try using this equation: fbk=(fck-1.77)/0.83 where fbk is cubic concrete strength and fck is cylindrical strength.

Because I say so.

Why concrete cube has high strength than cylinder?

Reasons for concrete cube to have greater compressive strength as compared to cylinder iscontact area of a standard cube mould with the upper platen in the testing machine is more which results in more confinement .more confinement resist against specimen expansion resulting in more compressive strength
