The work concerns test results of cement concrete and the use of similarity analysis of distance course. Research procedure was presented and the obtained laboratory tests results were discussed. Composition of concrete mixes were designed. The cement concrete composition includes cement, coarse aggregate, fine aggregate, water, admixtures and a ceramic addition. The addition of ceramic was used as a replacement for part of the fine aggregate Fresh concrete mixture parameters were tested and basic parameters of hardened concrete were defined (density, compression strength and tensile strength). The scope of works included concretes intended for airfield pavements and this concretes after frost resistance test. The test has been conducted in diversified media generally used in the course of winter maintenance. 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. The following zones were subject to analysis: cement matrix, contact area between air pores and cement matrix, contact area between fine aggregate and cement matrix and contact area between coarse aggregate and cement matrix. Based on the results obtained diagrams similarity of the analysed concretes were prepared.
