THE USE OF FRACTAL GEOMETRY FOR THE ASSESSMENT OF THE DIVERSIFICATION OF MACRO-PORES IN CONCRETE

Janusz Konkol, Grzegorz Prokopski

Abstract

The article presents the results of examination of the fractal dimension D of macro-pores in concrete. The concretes were made from coarse basalt aggregate. Fractal examinations showed that the fractal dimension D of macro-pores in concrete was different, depending on the water-cement ratio W/C. The performed examination of macro-pores in concretes has shown the existence of a statistically significant correlation between the fractal dimension DBC, as determined by the box method, the relative number of pore crosssections NA (or the number of pores N) and the total air content A, as well as between the fractal dimension DBC, the relative number of pore cross-sections NA and the water-cement ratio W/C.
