Based on the analysis of the obtained laboratory test results, the article presents the suggestion concerning the use of quartz and syenite aggregate as granite aggregate alternative, in the composition of cement concrete intended for airfield pavements. The scope of laboratory tests with regard to rock materials included the assessment of basic properties of the applied aggregates and their influence on the change of parameters of internal structure of hardened cement concrete. The analyses included evaluation of the selected aggregate parameters, i.e. bulk density, absorbability, sand equivalent, abrasion, crushing and polishing resistance. The influence of the applied materials on the change of the basic physical properties (bulk density and absorbability) was specified and mechanical parameters (compressive, splitting tensile strength and bending strength) of the curing concrete within diversified periods. According to the observed changes in the internal structure of concretes, the influence of the aggregate type on the obtained parameters of hardened concretes and their airfield pavement application were determined.
