Book Synopsis Hydraulic Conductivity Assessment of Hydraulic Barriers Constructed with Paper Sludge by : X. Wang

This book was released on 2000 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper sludges are being used with increasing frequency for construction of hydraulic barrier layers in landfill final covers because they often have substantial clay content and relatively low hydraulic conductivity. This paper addresses the assessment of the hydraulic conductivity of paper sludges using data obtained from a series of laboratory and field tests conducted on two barrier layers constructed with paper sludge that were part of final cover test sections. Field hydraulic conductivities were measured using sealed double-ring infiltrometers (SDRIs) and two-stage borehole permeameters (TSBs). Laboratory tests were conducted in flexible-wall permeameters on undisturbed specimens collected as blocks and in thin-wall sampling tubes as well as remolded specimens. The in-service hydraulic conductivity, computed from water balance data, was also available for comparison. Analysis of the data shows that similar hydraulic conductivities are measured in large field tests and on small laboratory specimens regardless of whether the specimens are undisturbed or remolded. Based on the analysis, recommendations are made regarding the need for field testing, laboratory and field test methods, and sampling techniques.
Book Synopsis Geotechnics of High Water Content Materials by : Tuncer B. Edil
Download or read book Geotechnics of High Water Content Materials written by Tuncer B. Edil and published by ASTM International. This book was released on 2000 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reasonable estimates indicate that approximately a billion cubic meters of high water content soil-like wastes are produced annually worldwide, and a large portion of these are deposited hydraulically in diked impoundment areas, some of which are among the largest earth structures in the world. The major problems emanating from this disposal method are the difficulty in dewatering the wastes, their low strength and hydraulic conductivity, their high compressibility, their potential to contaminate the groundwater, the stability of the confining dikes, and the ultimate reclamation of the disturbed land. Following a brief explanation of how many of these wastes are generated, quantitative values for key engineering properties are summarized and compared for a wide variety of waste materials and some reference soils. Then, many concepts that have been applied with success will be presented together with the advantages each offers, the difficulties involved in using it, and the limitations in our knowledge. Discussed briefly will be state-of-practice developments in mathematical modeling, laboratory testing and associated interpretations, and material property formulations.

Download or read book The Exploitation of Natural Resources and the Consequences written by R. W. Sarsby and published by Thomas Telford. This book was released on 2001 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the pressure to conserve agricultural land and green-field sites has grown it has become increasingly important to reclaim land that has been damaged by past industrial usage, e.g. areas of mining subsidence, tailings dams and lagoons. Furthermore the need to conserve primary aggregates is providing an impetus for re-use of waste materials in engineered construction.This book is the proceedings of the GREEN3, the third in a four-yearly series of international symposia that discuss aspects of geotechnical engineering intimately related to the environment.

Book Synopsis Hydraulic Conductivity of Solidified Residue Mixtures Used as a Hydraulic Barrier by : C. Guven
Download or read book Hydraulic Conductivity of Solidified Residue Mixtures Used as a Hydraulic Barrier written by C. Guven and published by . This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using a solidified product of steel process residue in construction of a barrier system was investigated in the laboratory and in-situ. A solidified product of the dewatered sludge residue, filter cake, which exhibited high strength and low hydraulic conductivity was considered as a barrier cap for an existing lagoon. Variations in the placement and curing methods in the field, along with additive composition of the base mixture, influenced the strength development, hydraulic conductivity and durability of the resulting material. Strength of the material did not correlate well with hydraulic conductivity. However, high material strength appeared to increase resistance to freeze-thaw effects, thus demonstrating resistance to deterioration of the desired low permeability. Compositional variations such as proportion of surface reactive agents, water to cement ratio and the proportion of cement influenced strength as well as the measured hydraulic conductivity in the laboratory. Finally, a comparative analysis of fraction of three heavy metals removed by water permeation of three different composite samples demonstrated that chemical processes during the solidification may play an active role in the performance of the final product. Three slightly different composites of fairly high strength and low hydraulic conductivity showed selective release of cadmium from the solidified material.
