The fractal dimension of stone pore surface as weathering descriptor

Pore surface fractal dimension of building stones were measured using mercury porosimetry in a pore diameter range from 100 to 0.012 mm. Surface fractal dimension can be used as descriptor of the stone pore surface, allowing an easier differentiation between weathered and unweathered stone than the pore size distribution. For the studied materials, weathering processes cause an increase in the surface fractal dimension. q2000 Elsevier Science B.V. All rights reserved
