FRACTAL DIMENSION OF THE POROUS STRUCTURE OF CELLULAR CON-CRETE

Abstract

The study of the fractal dimension of pores in cellular concrete and aerated concrete blocks significantly influences the understanding of the porous structure of materials. One of the key methods for estimating this dimension is cell counting. The fractal dimension of pores indicates the degree of their dense distribution and is closely related to the physical properties of the material, such as heat and sound insulation. The results of the study showed that an increase in the fractal dimension of pores is associated with an increase in the number of smallest pores and the complication of their spatial arrangement. At the same time, the use of the cell counting method allows to estimate accurately this fractal dimension, based on the number of cells containing pores at different scales. One of the significant aspects is the correlation of the fractal dimension of pores with their area and size. This makes it possible to evaluate the roughness of pores and their distribution in the material, as well as to understand how an increase in pore size leads to a decrease in their number and thickening of the walls between them. The fractal dimension of pores makes it possible to characterize the structure of the pore space, which is important for understanding the microstructure of the material. Manipulating the microstructure of cellular concrete using fractal dimension analysis can improve its thermal insulation, strength and sound insulation, opening new possibilities for creating more efficient building materials
