	The article analyzes cracking patterns on the surface of a cement matrix modified with polypropylene fibers. Cracks analyzed were caused by the effect of an elevated temperature. In order to quantify cracking patterns, image analysis tools were used to define three stereological parameters. In total, 4 series of samples were tested, two of them were modified with polypropylene fibers. In each individual series the samples were made with a variable w/c ratio, which was equal to 0.4, 0.5, and 0.6 respectively. A microstructure analysis was also carried out using a scanning electron microscope and an X-ray microanalyser. The results obtained allowed to determine the impact of polypropylene fibers on the geometry of thermal cracks of pastes, which was largely dependent on the class of the cement used. The elements of the theory of dispersion systems were used to explain the ongoing relationship.
