Fractals, Pore Potential, and Sphinx Limestone Durability


A study of the porosimetric data of limestone samples from the region of the Sphinx reveals that the pore volume distributions obey a power law. It should be possible, therefore, to treat these strata as a fractal structure. We found that each lithologic unit of the Sphinx, below the neck, can be characterized by a fractal dimension D, the values of which range from 2.54 to 2.77. The volume of small pores, radii < 0.9μm, ranges from 19% for D = 2.54 to 61% for D = 2.77.

A good correlation, with a correlation coefficient of 0.97, was found between the durability factors as previously determined through pore-size distributions and those determined through the fractal dimension.
