Available in PDF, EPUB and Kindle. Book excerpt: The quality of the contact portland cement grout and surrounding rock will be of prime importance if grout is used to seal boreholes for the isolation of nuclear waste. The contact will need to be tight and relatively impermeable. In the study reported herein, simulated borehole (SBH) specimens were prepared and tested in the laboratory. The specimens consisted of grout poured into a hole in sections of anhydrite rock core that had been grouted into a steel pipe to provide restraint. The study was largely devoted to investigating methods of avoiding artifacts during preparation of these SBH specimens for study of the grout-to-rock contact. The work was conducted and is reported in two parts. The first part was a study in which only large round SBH specimens (about 6 by 6 in.) were used, while the second also included some smaller round SBH specimens (about 3 by 3 in.).

Available in PDF, EPUB and Kindle. Book excerpt: Portland cement grout identified as BCT-1-FF (Bell Canyon Test 1-FF) was used in borehole plugging experiments in the Bell Canyon Tests in Hole AEC-7 at the Waste Isolation Pilot Plant site in New Mexico during September 1979 and February 1980. This grout was made with fresh water. A study of this grout was begun in August 1979 in the laboratory to evaluate the possible effects of temperature, pressure, and storage in fresh water or simulated groundwater (brine) on its phase composition and compressive strength at early ages. Phase composition was determined by X-ray diffraction. Temperatures ranged up to about 150 F and included elevation at a few hours age after mixing; pressure was as high as 1500 psi; specimens were stored in simulated groundwater (brine) or in fresh water. Data from 1 to 90 days showed: Higher temperature accelerated early strength gain. These differences essentially vanished by 90 days age. Hydration products as identified by X-ray diffraction were normal; this indicated that a temperature range of 78 to 153 F was not significant. Pressure did not affect composition. Storage in simulated groundwater (brine) or fresh water had no detectable effect. Since the BCT-1-FF grout mixture contained added sulfate, it formed more ettringite as judged by X-ray diffraction than comparable portland cement mixtures without added sulfate. (Author).

Download or read book Examination of ERDA-10 Grout Specimens at Different Ages written by Alan D. Buck and published by . This book was released on 1981 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A borehole designated ERDA-10 was filled with portland cement based grout in October 1977. The borehole is located in Eddy Co., N. Mex. The hole was filled with grout of four compositions, three of which were similar and made with salt water as mixing water; the upper portion of the hole was filled with a grout made using fresh water as mixing water. During the filling operation, test specimens were cast using these grouts. The deepest plug (plug 1) was cored 48 hours after placement. During the filling operation, test specimens were cast using all four grout compositions. The core from plug 1 and the test specimens were sent to the Structures Laboratory of the U.S. Army Engineer Waterways Experiment Station for physical tests and petrographic examination. They were stored in the laboratory at temperatures ranging from about 23 C to 54 C. Tests and examinations were made at three ages: (a) 23 + or - 8 days, (b) approximately 1 year, and (c) approximately 3 years. This report presents the results of the petrographic examination which included use of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The grouts made with salt water formed tetracalcium aluminate dichloride-10-hydrate (C3A(CaCl2)H10) at the expense of ettringite during continued hydration. The C3A(CaCl2)H10 was already present when the grouts were examined at the early ages (23 + or - 8 days).

This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sealing of boreholes and underground excavations has not received much engineering attention until fairly recently. The growing awareness of and sensitivity to environmental concerns of the technical community as well as of the public at large has resulted in an increasing recognition of the fact that these geological penetrations may have an environmental impact. The issue of possible contamination resulting from migration along boreholes, adits, shafts or tunnels unquestionably has been raised most forcefully with in the context of nuclear waste disposal. Several nuclear waste disposal programs, notably the Civilian and the Defence programs of the US De partment of Energy, the US Nuclear Regulatory Commission and the Canadian and Swedish radioactive waste disposal programs have conducted major research efforts aimed at developing adequate seal designs for penet rations in host rock formations for high-level nuclear waste repositories. While a considerable data base has been gathered over the last two decades or so with regard to the performance of seals, most of the information is presented in research reports and widely scattered papers in journals and proceedings of conferences. Hence, the materials are not readily accessible to potential users such as designers, contractors or regulators who are not familiar with nuclear waste disposal programs.

Book excerpt: An introduction for courses that involve some knowledge of glacial geology and sediments of formerly glaciated terrains. The early chapters describe depositional processes at modern glacier and ice-sheet margins relating sediments and landforms in recurring "landsystems". Later chapters portray the distribution of these landsystems in Pleistocene glaciated terrains of the mid-latitudes, focussing on commonly encountered problems in various fields from stratigraphic and sedimentological investigations to construction problems relating to roads and dams. The resulting text is a summation of a large body of literature previously accessible only to specialists. A substantial reference list is complemented by cross-references throughout.
