Determination of Thermal Conductivity and Porosity of Building Stone from Ultrasonic Velocity Measurements

Abstract

Ultrasonic velocity measurement, a non-destructive and easy method to apply in both field and laboratory conditions, has increasingly been conducted to determine the physical properties of rock materials. This paper presents an experimental study of the measurement of P-wave velocity, thermal conductivity and porosity of several types of sedimentary, metamorphic, and magmatic rocks. The aim of this study is to predict the rocks properties including their thermal conductivity and porosity using P-wave velocity. For this purpose, the physical properties are determined in the laboratory to obtain correlations between P-wave velocity and physical properties. Consequently, good linear relationships are found between all the determined physical properties and the P-wave velocity measurements.

Petrophysical properties of volcanic rocks and impacts of hydrothermal alteration in the Guadeloupe Archipelago (West Indies)

“…Lippmann & Rauen GbR. The technique is based on the change in surface temperature after a known and set heat input and could be applied to a large range of geological materials (Boulanouar et al, 2013;Rosener, 2007;Stanek, 2013;Surma and Geraud, 2003). The measuring instrument includes a mobile plate composed of three thermal sensors and a heat source.…”

Study on P-wave and S-wave velocity in dry and wet sandstones of Tushka region, Egypt

“…Hicks and Berry [14] list the parameters influencing velocities in rocks which may be summarized as follows; (1) Rock framework as elastic constant of grains, density of grains, type of cementing material, pressure on skeleton lithology and porosity, (2) Fluid contained in pore spaces as density of fluid, pressure on fluid, and compressibility of fluid and (3) Temperature of medium, where the change in temperature over the range from 25-150°C causes velocity change in dry rock either shale or sandstone causing 5-7% reduction in velocity for saturated cores under equal hydrostatic and skeleton pressure [15]. (4) Depth and elevated overburden pressure, where the velocity increases logarithmically with increasing in depth and rock pressure as well [5]. The overburden pressure increases seismic velocity, while its associated high temperature decreases it.…”

“…The compressional wave velocity in the liquid-wet porous material will generally be higher than that in the dry case, except for material having low bulk compressibility [3]. High values of the P-wave velocity are obtained for saturated samples and low values are obtained for dry samples (P-wave velocity (dry) < P-wave velocity (saturated)) [4]. The shear wave velocity decreases as the water saturation increasing until it reaches 70-75% and then starts to increase again [9].…”

Improved petrographic-coded model and its evaluation to determine a thermal conductivity log

“…They additionally used density logs for the correlation. Oezkahraman et al (2004) described the derivation of thermal conductivity from p-wave velocity for building rock types. Kukkonen and Peltioniemi (1998) related thermal conductivity, density, magnetic susceptibility, and compressional wave velocity for 2705 different rock types (plutonic rocks, dykes, volcanic rocks, sedimentary, and metamorphic rocks) from Finland.…”
