Study of the effect of moisture content and bending rate on the fracture toughness of rocks

Popis výsledku v původním jazyce

Generally, rock material failure is c ontrolled by cracks under specific conditi ons. The study of rock fracture toughness belongs to the current frequent directions of research in the area of rock failure. The present paper describes the effects o f parameters influencing the resultant pr operties of rock materials (bending rate , rock moisture) during fracture toughness measurement of different kinds of rocks (sandstone, marble, granite). The highest fracture toughness values were found in the marblesamples. This is probably due to the inner structure of analysed marble, which is composed of only one mineral (calcite) and also has a lower porosity th an the used granite. The lowest fracture toughness values were found in the sandstone sample, and reached c. 17?30 % of the measur ed fracture toughness values of the analys ed granite and marble samples. As in the case of the other mechanical properties of rocks (e.g. uni axial compressive strength) also in the case of higher sandstone
