Physical, electrical and mechanical properties of granitic and limestone rocks with emphasis to their chemical composition

Abstract

The mechanİcal, physical and electrical properties in addition to the chemical constitution have been measured for some samples of the most common roeks; granite and limestone. Besides, factor analysis was applİed giving rise to four specific factors controlling the mechanİcal behaviors of each rock type. In granite; the two most common factors measure the degree of rock compactness in terms of density, porosity and chemical constitution (Fe, Ca, K and Cr) and correlate the relation between mechanİcal, electrical and chemical constitution. Also, the limestone rock exhibits two most common factors. The first one measures the electrical properties in terms of porosity and other chemical elements such as: Ti and K, while the second factor measures the degree of silicification in terms of both Ca and Si.

Estimation of Elasticity of Porous Rock Based on Mineral Composition and Microstructure

“…In the formulation of suitable constitutive models, the material parameters should be determined first from relevant experimental data in order to describe the mechanical behaviors of rock materials under different engineering contexts [1]. Classical deterministic approaches [2][3][4] have been firstly used to identify the physical properties of rock materials, generally based on laboratory experiments [5][6][7][8][9] and in situ tests [10,11]. However, these tests sometimes are difficult to be realized and may involve heavy costs.…”
