The prismoidal compressive strength of concrete has been found to decrease with the increase in the ratio of height 'h' to lateral dimension 'd' till it reaches a value of 4 (h/d=4), beyond which it approximately remains constant equal to 0.7 times the strength of cube for which h/d ratio equals to unity.

Compression machines for strength tests on concrete …

Crushing failures occur due to strength problem, when the compression demand becomes more than compression capacity of column so crushing failure occurs. While buckling failure is associated with length of the column and you should choose your effective length of the column more safely to avoid this buckling failure.
