Compressive Strength Test of Concrete (Cube)

1. The compressive strength of 100 mm cube as compared to 150 mm cube is always:
2. The strength of concrete after one year as compared to 28 days strength is
3. Under pure uniaxial compression loading, the failure cracks that appear in a cube specimen should be
4. During compressive strength of cube test, under uniaxial compression loading including platens effect, the failure cracks that appear in a cube specimen are
