Concrete cubes break more at the middle due to the distribution of stress and the presence of weak points.

• The middle of the cube experiences the highest stress during compression testing.

• The distribution of stress is not uniform throughout the cube.

• The presence of weak points, such as air voids or aggregate discontinuities, can cause the cube to break at the middle.

• The middle of the cube is where the maximum compressiv...read more
