    Analiza korelacji miedzy parametrami morfologii powierzchni przełomów betonów
    (Видавництво Національного університету «Львівська політехніка», 2007) Konkol, J.; Prokopski, G.
    In article the results of investigations of fracture surfaces of concrete has been shown. Determined the profile lines development factor RL and the fracture surfaces development factor RS, versus composition of concretes as well as the dependence between fractal dimension D and parameters RL and RS. The existence statistical correlation between fractal dimension D and these parameters has been shown too. With growth the both fractographical parameters (RL and RS) enlarged oneself also the value of fractal dimension.

    Porowatosc betonu wyznaczona metodami stereologicznymi oraz jej wpływ na własciwosci mechaniczne betonu
    (Видавництво Національного університету «Львівська політехніка», 2007) Konkol, J.; Tomasik, A.
    In this article introduced results of experimental research of air void of concrete from use the parameters the stereological by the computer programme FRAKTAL_Stereolog. The subject of research was to examine the influence of water-cement ratio in concrete mixture on durability properties of natural gravel concrete in view of fracture mechanics too. Existence of relationship between the composition, the structure and properties of the tested concrete has been proved on the basis of the executed research.

    Wpływ parametrów fraktograficznych i porowatosci na odpornosc na pekanie betonów bazaltowych
    (Видавництво Національного університету «Львівська політехніка», 2007) Konkol, J.
    The results of basalt concrete research with the changeable water-cement ratio and coarse aggregate share have been presented in the paper. The executed research have been concerned analysis of the structure and morphology of the concrete fracture surface. The air porosity of the concrete has been analysed determining steorological parameters of the pores and coarse aggregate and also fractographic parameters of the fracture surfaces from the research of fracture toughness.
