Gefügeabhängigkeit technischer Gesteinseigenschaften
By virtue of their usually complex geological past, natural stones represent a heterogeneous and anisotropic material. Their use demands good knowledge of their technical properties. In this study, 20 low-porosity crystalline rocks of different mineralogical compositions and rock fabrics (granitoids, gabbros, peridotite, quartzite, marble) were investigated with respect to the fabric dependency of the technical stone properties. The samples could be classified into three macrostructural groups according to their macroscopic fabric anisotropy. The mica texture was determined in 14 of the stones. The maximum intensity (Imax) increased proportionately to increasing fabric anisotropy, enabling definition of Imax for macrofabric groups I/II/III. Additionally, the crack density of the microcracks, their preferred orientation and the grain size were taken into account
