The determination of deformation parameters of rock material is an essential part of any
design in rock mechanics. The goal of this paper is to show, that there is a relationship …

Studies of rates, processes and modes of rock surface, and near-surface, deterioration, and
also hardening, are central to rock weathering and building stone research, conservation …

Recent technological developments in the field of non-destructive techniques have
enhanced their usefulness in the field of built cultural heritage protection, and are …

Shales are considered to be both source and cap rocks, and play an important role in
various geotechnical applications including oil and gas exploration and production. A deep …

Microcracking induced by wide fluctuations in temperature affects granite quality and
durability, making the stone more vulnerable to decay. Determining the extent of that effect is …

Mechanical characterization of hydrothermally altered rocks from geothermal reservoirs will
lead to an improved understanding of rock mechanics in a geothermal environment. To …

Gas permeability is commonly used to evaluate durability characteristics of concrete.
However, these values are often achieved using never stressed or damaged specimens …

The relationship between the static and dynamic elastic modulus in rock materials has been
frequently addressed in scientific literature. Overall, when it comes to the study of materials …

Columnar jointed basalts are characterized by a self-organized joint network of
discontinuities and pose a difficult challenge for geotechnical engineering design due to …
