  • Application note issue #5 - Cement Analysis August 2017

    Cement analysis using FP program (Fundamental Parameters) Cement is a blend of several minerals. It is critical to control the elemental composition and properties such as strength, setting, time and color. ED-XRF is being used to analyze the raw components, raw meal, clinker, and the final cement product (Na, Mg, Al, ...

  • The geological strength index: applications and limitations

    The geological strength index (GSI) is a system of rock-mass characterization that has been developed in engineering rock mechanics to meet the need for reliable input data, particularly those related to rock-mass properties required as inputs into numerical analysis or closed form solutions for designing tunnels, slopes or foundations in rocks. The geological character of rock material, together ...

  • Special purpose mapping for waste disposal sites: Report of IAEG Commission 1: Engineering Geological Maps

    This report results from work that was first proposed to a meeting of the International Association of Engineering Geology (IAEG), Commission No.1 held in Bratislava (Slovakia) in 1992. Following the publication of the Commissions report on Engineering Geological Maps (Engineering geological maps (1976) and reports on the description and classification of rock and soil and on recommended symbols ...

  • Principal provisions of engineering and geological survey methodology in designing and construction of underground laboratory as a part of facility of RW underground isolation

    The most critical moment is the choice of a site for radioactive waste geological repository. Here the role of engineering and geological prospecting as a basis for the construction of a facility for underground isolation appears especially important; it is followed by finding a suitable area and subsequent allocation of the site and facility construction sites. The decision on the selection of ...

  • The total engineering geology approach applied to railways in the Pilbara, Western Australia

    The application of the total engineering geology approach to the investigation, design, construction and operation of several major iron ore railways in the ancient cratonic Pilbara region of Western Australia is described. The approach is based on developing a thorough understanding of the geological and geomorphological history of the area and adopting strategies such as staged investigations, ...

  • Introduction to C. A. Hogentogler Award Article by David I. Stannard

    The 1991 C. A. Hogentogler Award was presented to David I. Stannard of the United States Geological Survey in Denver, Colorado. The Hogentogler Award is presented to the author or authors of a paper of outstanding merit on soil or rock for engineering purposes published by the Society. The award was established in 1953 to stimulate research, encourage the exchange of knowledge, and recognize ...

  • Development and Potential of Core-Logging Manuals

    Characterizing the in-place conditions of rock masses commonly depends upon continuous diamond-core drilling for site investigation or resource characterization. However, because of incomplete or inconsistent core descriptions, potentially valuable information may be lost or unavailable for other users. This situation suggested the potential value of photographic core-logging manuals and ...

  • Knowledge management for radioactive waste disposal: moving from theory to practice

    The exponential growth in the knowledge base for radioactive waste management is a cause for concern in many national programmes. In Japan, this problem is exacerbated by a volunteering approach to siting of a deep geological repository, which requires particular flexibility in the tailoring of site characterisation plans, repository concepts and associated Performance Assessments (PAs). ...

  • The future of stochastic and upscaling methods in hydrogeology

    Geological formations are complex features resulting from geological, mechanical, and physico-chemical processes occurring over a very wide range of length scales and time scales. Transport phenomena ranging from the molecular scale to several hundreds of kilometers may influence the overall behavior of fluid flow in these formations. Heterogeneities that cover a large range of spatial scales ...

  • Three–dimensional oil and gas pool–forming dynamic simulation system: principle, method and applications

    Based on the theories and methods of system engineering, the reconstruction of physical space for oil and gas generation, expulsion, migration, accumulation and diffusion is realised by combining the dynamics simulation with topological structure simulation and applying the topological structure simulation. The integral non–linear process of petroleum system is described successfully with the ...

  • Spatial pattern of arsenic contamination in shallow wells of Bangladesh: regional geology and nonlinear dynamics

    Since the discovery of large-scale arsenic contamination of groundwater in Bangladesh more than a decade ago, studies related to its spatial characterization have relied on geostatistical approaches and the classical notion of linear stochastic dynamics. This study explores an alternative nonlinear approach, with a motivation to possibly achieve more cost-effective solutions for Bangladesh. It ...

  • Leakage from drill pipe casing subject to shear deformation

    The possibility of fluids leaking from a pressurised drill pipe casing subject to shear deformation caused by various events, including geological activity (such as seismic activity or deformations associated with subsidence related to excavation and construction) in the vicinity of the bore hole, is investigated. An experimental laboratory scoping investigation has been conducted to determine ...

  • Waste Disposal

    Introduction The final step in the waste management process is waste disposal, the permanent isolation of waste. Some wastes can be managed and disposed safely with existing facilities and proven methods. Other Department of Energy (DOE) wastes require more complex disposal facilities. DOE has conducted extensive research into alternative waste disposal methods and has concluded that deep ...

  • Water for Southern California: water resources development at the close of the century.

    INTRODUCTION In 1999, California observes the 150th year of the Gold Rush. Rather than an isolated historical event, it could be argued that the California Gold Rush never really ended, but rather that it was the first chapter in a mass migration unlike any other in history, both in scale and duration. At the founding of the Missions by Franciscan friars, Alta California was almost an ...

  • Newtons Cove Coast Protection Scheme

    Using tried and tested techniques, B&V Water River & Coastal Management experts replaced an existing seawall and won an environmental award in the process. The chilled rough waters of the English Channel have pounded and eroded the coast of England for millennia causing present day problems for towns and villages clustered close to the sea since ancient times. In the county of Dorset on ...
