Abstract: The work presents the applied similarity methods of distance courses in case of cement concrete intended for airfield pavements. Composition of concrete mixes were designed and their parameters were defined. Compressive strength of hardened concrete and components thereof and the occurrence of crystal phases were determined. Subject to observations of internal structure of concretes and conducted chemical micro analyses using scanning electron microscope, the contents of diversified elements in four zones were specified. Similarity indexes between input and target sequence were defined. Diagrams presenting the similarity of the analysed concretes were prepared. It was proved that the suggested method can be used to assess the elements content and define the similarity of concrete intended for airfield pavements.
