Description:

Physical mass properties of various types of rocks were ascertained, and their relationships are discu ssed in this article. Basedon water permeability and mercury intrusion porosimetry methods, conductivity coefficient, porosity, and pore size distribution were determined. Furthermore, bulk and particle densities of rocks we re determined. All laboratory tests were carried out according to Czech versi on of the Technical specif ication CEN ISO/TS 17892-11:2004. The above-mentioned specification has the status of the Czech standard (ČSN, CEN). Permeability and porosity are in close relation, and it could be assumed that its relationship is linear, i.e., with increasing porosity, permeability increases as well. This relationship is influenced by other rock properties, such as the amount of open and closed pores with in the rock sample, size, and distribution of pores or mineral admixtures. From this point of view, it is necessary to study these physical properties of rocks as well, because this enables an overall analysis of rocks and its possible use for engineering constructions, Jan Šperl and Jiřina Trčková., and Obsahuje bibliografické odkazy
