Wpływ parametrów fraktograficznych i porowatosci na odpornosc na pekanie betonów bazaltowych

Abstract

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.
