Available in PDF, EPUB and Kindle. Book excerpt: The phase composition of pore water in three types of rock subjected to temperature below OC was explored by a variety of techniques. Freezing point depression was measured as a function of water content by differential thermal analysis, the results yielding relationships between unfrozen water content and temperature. In an effort to avoid the practical difficulties involved in differential thermal analysis, attempts were made to determine freezing characteristics indirectly by air penetration and mercury penetration techniques applied at ordinary room temperatures. Electrical conductivity measurements were made as a function of temperature down to -195C in an attempt to obtain information on characteristics of interfacial water films at low temperatures. Thermal strain was measured as a function of temperature in order to detect direct mechanical effects associated with phase changes, chiefly strain discontinuities brought about by volume changes in the pore water during rapid freezing and thawing. Finally, isothermal compressibility whether the rock underwent step changes in volumetric strain at pressures corresponding to those of the phase boundaries for ice polymorphs. (Author).

Download or read book Advances in Cold Region Thermal Engineering and Sciences written by Kolumban Hutter and published by Springer Science & Business Media. This book was released on 1999-08-11 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of peer-reviewed articles and reviews presented as lectures at the Sixth International Symposium on Thermal Engineering and Sciences for Cold Regions in Darmstadt, Germany. It addresses all relevant aspects of thermal physics and engineering in cold regions, such as the Arctic regions. These environments present many unique freezing and melting phenomena and the relevant heat and mass transfer processes are of basic importance with respect to both the technological applications and the natural context in which they occur. Intended for physicists, engineers, geoscientists, climatologists and cryologists alike, these proceedings cover topics such as: ice formation and decay, heat conduction with phase change, convection with freezing and melting, thermal properties at low temperature, frost heave and permafrost, climate impact in cold regions, thermal design of structures, bio-engineering in cold regions, and many more.

Download or read book Strength and Deformability of Rocks at Low Temperatures written by Malcolm Mellor and published by . This book was released on 1971 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strength tests were made on three types of rock, both 'air-dry' and water-saturated, at temperatures from +25 to -195C, and stress/strain tests were made down to -60C. Strength of air-dry specimens increased with decreasing temperature at an average rate of approximately .002/C and quasi-elastic moduli increased at comparable rates. Static fatigue mechanisms in air-dry rock were apparently influenced by temperature-modification of adsorbed water. Strength of water-saturated specimens increased dramatically as pore water froze, and continued to increase down to -120C, where compressive and tensile strengths were greater than room temperature values by factors of 5, 4 and 2 for sandstone, limestone and granite respectively. Compressive stress/strain curves for saturated rocks became steeper after freezing, and initial tangent moduli for saturated high porosity rocks increased by well over an order of magnitude.

Available in PDF, EPUB and Kindle. Book excerpt: An airborne electrical resistivity survey was flown near Fairbanks, Alaska. One of the objectives of the survey was to evaluate the potential of airborne VLF resistivity mapping to distinguish between rock types. The impetus for the study was the requirement by the U.S. Army Engineer District, Alaska, for a rock quarry in connection with the Chena River Lakes Project. The general area is near the southern limit of the rolling Yukon-Tanana Uplands. The bedrock consists of both the common Birch Creek schist and local intrusive igneous rocks.
