... Peat is a useful oil absorbent for controlling marine oil spills and the leakage of petroleum-derived hydrocarbons into groundwater. In the present study, the ability of peat as an oil absorbent is assessed based on a column test that provides data on the retention of kerosene in the peat under...

... Fundamental thermal properties of various high water content materials were determined using a number of thermal testing methods. Tests were conducted on peat soils, solid wastes, industrial sludge, and bentonite slurries. Thermal conductivity, heat capacity, and thermal diffusivity were...

... Peats and organic soils are encountered in many geographical areas and because of their organic solids and high water content they exhibit mechanical properties somewhat different than the customary behavior of inorganic clays. Shear strength and coefficient of earth pressure at-rest are two...

... This paper presents laboratory findings in peats from two different Italian sites; the tested peats are typical of superficial deposits near the Northern Adriatic Coast. Standard and special laboratory tests were carried out on undisturbed soil cores. In particular, oedometer tests in standard...

... to an industrial building. The rational developed to explain the soil behavior at the site, which includes layers of peat, illustrates the important role of seepage pressures during rapid transients. During rapid lowering of the phreatic surface, the initial soil compression is controlled by total stresses...

... Reconstruction of State Highway 29 (STH 29) in north central Wisconsin was complicated by two separate deposits of compressible peat and organic silt within the highway right-of-way. The deposits ranged from about 3 to 11 meters in thickness over about 900 meters of the reconstruction alignment...

... Biological formulations have evolved from the use of organic based solids such as peat as a preservative and delivery system to water based carriers. Water based formulations provide more convenience for the end user. Innovations in media preparation, stabilizing agents and packaging have led...

... Consolidation tests have been conducted on a fibrous peat using a 254-mm-diameter hydraulic oedometer which was modified to accommodate force and pressure transducers. These transducers were used to evaluate the side friction acting on the peat and to record the distribution of applied pressure...

... In recent years there has been an increased interest in peat both as a precursor of coal and as an alternative fossil fuel. One of the most important tests used to evaluate or describe peat is measurement of its inorganic (or ash) content. Numerous methods for determining ash content have been...

... A procedure is described for making relatively undistorted, oriented microtome sections of peat for microscopic analysis. This simple procedure results in a permanent sample from which data can be produced that are precise, statistically reproducible, and easily transmitted and compared...

... for determination of several physical and chemical characteristics. The peat type and decomposition of each sample were recorded to enable grouping of results. The determinations made are dependent on the utilization potential of the site. Calculations were performed with the aid of a computer. Information can...

... The New Brunswick Department of Natural Resources has carried out a detailed inventory of the peatlands in the Province. The compiled information includes estimates of the in situ volumes of peat in each deposit. When a peat mining development is being considered, it is often desirable...

... The United States has large deposits of peat, with recoverable fuel value roughly estimated at 538 quads (10 15 Btu), which is equivalent to 90 billion barrels of oil. The potential importance of peat as a feedstock for gasification and as a fuel source is currently being evaluated by the U.S...

... either a 4-cm piston sampler or a 10-cm Macaulay sampler. The core was subdivided into sample intervals on the basis of changes in peat type and humification (decomposition). The samples were oven-dried and calorific value was determined. Ash content was also determined to facilitate comparison...

... Two samples developed at the University of New Brunswick for sampling of peat are described. One is a 100-mm-diameter piston sampler with a Plexiglas insert sample holder and the other is a 250-mm-square block sampler. The samplers have been extensively tested and used in Sphagnum and sedge...

... The behavior of peats under varying loading processes was noted by the authors while working on various geotechnical engineering projects. This paper gives the comparative results of repeated short-term loading tests and continuous one-load consolidation tests on peats. Peat samples were...

... undesirable geotechnical properties. The geotechnical problems facing the islands which are related to the peat are oxidation, seepage and erosion loss, low strength, light weight, and high compressibility. The oxidation, compressibility, and wind erosion of the peat and other soils cause subsidence at a rate...
