The crystal structures were refined from Xray powder diffraction data (structure type ZrFe6Ge4, Pearson symbol hR33, space group R3m (#166)).
The structure type ZrFe6Ge4 can be considered as a linear hybrid of the structure types CaCu5 and Fe3Sn2, or as the structure resulting from an inclusion of R atoms into the Fe3Sn2 type [12].

The paper presents the study of morphological characteristics of cement particles and reveals the influence of the structure of the cement grain composition on the physical and mechanical properties of cement.
To study the grain structure, the samples have been divided into different fractions by sieve analysis.
Then the obtained images have been digitized to further study the grain structures (approximately 800 grains from each fraction have been studied).
