<p>Fly ash is a major by-product of thermal power plants that adversely affects land, water, and air. Its gainful utilization in many areas is being continuously explored. Use of fly ash in opencast coal mine haul road construction is one such option. This ...

The paper presents the results of experimental examination of the weathering grade of granite rock mass in the medieval Jeroným Mine (Czech Republic).

Based on mineralogical and technological investigations of the deposit “Greda” important characteristics of bentonite clay were determined. Representative samples of the deposit were characterized with X-ray diffraction, low-temperature nitrogen adsorption, ...

The majority of the thin intercalated sterile layers, which are coexcavated with lignite in the Southern Field mine of Ptolemais, Northern Greece, are petrologically characterized as marly limestones. This paper presents that the improvement of lignite quality, ...

<p>Over the past century the growth of American cities and towns, and the construction and maintenance of the highways and byways between those population centers, created a demand for enormous amounts of natural aggregate. Over that same period of time circumstances ...

The purpose of the study described in this report is to compile and synthesize information on the geology and engineering properties of Piedmont residual soils, and on geotechnical engineering design methods appropriate for use in these soils. Considerable ...

<p>Volcanic soils are widely encountered around the world and they underlay several cities, making an understanding of their geotechnical properties of great importance, particularly since the same geological processes responsible for their deposition also ...

The Geological Curators Group, which is affiliated to the Geological Society, was founded in May 1974 by geologists concerned about the poor standard of geological curation and consequent plight of geological collections in many of the museums ...

Industry uses bentonite for its inherent physical properties, or for the physical properties it can develop in another material or product. A thorough understanding of the chemistry and structure of bentonite, or more appropriately montmorillonite, ...

The principal bauxite deposits of Jamaica are located in the parishes of Manchester,St. Elizabeth and St. Ann. They are surface accumulations, and show a close relationship to the fault pattern of the region. This paper presents an overview of the ...
