Microcrack volumes in 87 granite-cored samples, obtained in the depth range from ground surface to 1000 m at Pinawa, Canada and Forsmark, Sweden, were quantified from stress–strain curves to assess the increase in microcrack volume with depth. Digi

Realistic texture-based modelling methods, that is microstructural modelling and micromechanical modelling, are developed to simulate the rock aggregate breakage properties on the basis of the rock actual microstructure obtained using microscopic obs

Rock aggregate products are essential for our infrastructure and society as a whole. Rock aggregates are mainly used for road and railroad construction and for the manufacture of asphalt and concrete. High-quality, low-cost, environmentally friendly

The properties of stone materials maybe divided into intrinsic properties such as chemical and mineralogical composition, grain size and porosity, and into functional properties related to a technical application. The latter describe how the stone re

Various methods were used in order to study how temperature cycling initiates changes in the porosity of fresh and impregnated marbles. The results indicated that intergranular decohesion was more pronounced in calcitic marble than dolomitic marble.

The use of thin (20–40 mm) marble as cladding for building facades has increased substantially during the last few decades. Many of the marble facades perform but some durability problems have occurred, especially with calcite marble, when the clad

Microcracking is highly dependent on the mineralogy, fabric, and microstructure of a given rock type. In this study, we investigate how crack initiation and propagation occurs during uniaxial cyclic loading. The mechanical test was performed on drill

Fabric-dependent anisotropy is important in understanding the mechanical behaviour of foliated rocks because the foliation creates mechanically weak discontinuities. Using optical microscopy, a foliation index (FIX) was calculated for a group of gran

Rock texture is of great importance in understanding the mechanical properties of a rock. Los Angeles and studded tyre tests were used to assess the mechanical properties of homogeneous acidic plutonic and volcanic rocks and these properties were rel

Image analysis is a technique used in a number of subjects, but to date not extensively used in the geological sciences. The paper describes the way image analysis is used in the various disciplines and presents an overview of the methods and its pot
