Application of similarity method of distance courses describing the elements content in concrete intended for airfield pavements

The work presents the applied similarity methods of distance courses in case of cement concrete intended for airfield pavements. Composition of concrete mixes was 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 microanalyses 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 could be used to assess the elements content and define the similarity of concrete intended for airfield pavements. The scope of works consisted of two stages. During the first one, two series of cement concrete were prepared. The analysis included cement concretes intended for airfield pavements, in compliance with requirements. The influence of variable environmental conditions with respect to standard ones on the selected features of hardened concretes was assessed.
