摘要: Abstract A comprehensive understanding of the fractal properties concrete meso-structure is important because it associated with complex and random mechanical behaviors concrete. The dimensions aggregates cement are derived discussed. An experimentation devised using X-ray computed tomography (CT) to determine each component meso-structure. dimension constant equal three, whereas that a real number less than three. definition for was introduced based on these two observations. comparison theoretical derivation indicates box-counting slightly greater value. Moreover, similar gradations have meso-structures.
