... are settlements of the slurry specimen, volumes of water extracted from the slurry specimen, and the changes in fluid content of the specimen. The results show that the sedimentation rate and velocity are varied and controlled by the applied voltage. From the test results, a significant investigation is derived...

... will ensure rapid consolidation. The underlying philosophy is to place a layer of sand on top of the slurry to accelerate consolidation. This paper summarizes the research carried out in Singapore. A pilot test and a large-scale project will be described and the results from monitoring discussed. A physical...

... A new dewatering system for slurry has been developed with the aim of realization of fficient mud-water treatment. In the system, centrifugal force is employed for the purpose of densification of mud and for separation of mud particles from water. In this research, an original idea has been...

... This paper describes a two weight system using bar and flat shaped weights for measuring depth and detecting sediment at the bottom of slurry-supported excavations. Currently there are no standard depth measurement weights or methods for reliably identifying bottom sediment. Two weights...

... This new technology was designed to form high-quality “formed-in-place” barrier walls in soil in a more continuous and uniform manner than the two-step, excavate and replace, processes of conventional slurry trenching. Soils in the path of the device are pulverized in-situ and liquified by high...

... Soil-cement slurry used in buried pipe installations has become an increasing popular choice for contractors. Flexible pipe, including PVC and RPM, as well as rigid pipe are being installed using this technique. The ingredients of the soil-cement can vary, but typically is a combination of soil...

... For the first time, a radical departure from solidly established concepts and practices based on the use of bentonite for trenching under slurry, is proving itself as a viable alternative. It is even more so in this age of acute environmental sensitivity. The role played by polymers...

.... Traditional construction methods that use trench boxes or shoring, sometimes in combination with dewatering systems, present a number of problems, particularly if the trenches have depths in excess of about five meters. The Bio-Polymer Slurry Drain (BP Drain) has provided a new method for constructing deep...

... and plastic viscosity, are determined in slurries made with cement which has up to 15% of limestone additions, in weight. For the same slurries the water retention value is obtained. The variations in the yield point and plastic viscosity showed the “lubricity power” of the smaller particles (below 10 μm...

... Four coatings, including tungsten carbide wear-resistant and cobalt-base corrosion-resistant materials, were tested for abrasion and erosion performance in silica sand and in Alundum slurries. A 1018 carbon steel sample was also tested for comparison. The abrasion tests were conducted with a wet...

... The relative erosivity (defined as the ratio of the rate of mass loss from a target specimen tested in one slurry and the rate of mass loss in another slurry) for coal-water, coal-oil, and petroleum coke-oil slurries has been determined using pot testers with a rotating flat-plate specimen...

... A coal and water fuel was recycled repeatedly through an erosion test loop. The effects of this on the fuel's erosiveness were studied. This was done to determine the feasibility of erosion testing using continuously recycled coal-water fuel. The erosiveness of the coal-water slurry was observed...

... Slurry erosion-corrosion tests were conducted on metallic materials of practical use by two kinds of testing apparatuses. One is a vibratory apparatus which uses a magnetostriction vibratory unit commonly used for the accelerated cavitation testing of materials. The other is a jet-in-slit...

... With the use of the Miller Number for slurry abrasivity and its usefulness in the slurry pumping industry in predicting pump wear, it became obvious that the same test could be run in “reverse” to determine the effect of a “standard” slurry on a candidate material, thereby giving a relative...

... In recent years, thin slurry walls installed by vibrating a beam into the ground and injecting a suitable slurry as it is withdrawn have been used successfully and economically in a variety of applications, most notably as ( a ) permanent seepage cutoffs either in new or existing dams or levees...

... This paper compares two methods of constructing vertical cutoff walls when considered in the context of controlling the migration of waste materials. It will be argued that the conventional slurry trench method has significant advantages over the vibratory beam injection (VBI) method...

... A fabrication method for silicon carbide (SiC) fiber-aluminum composites was investigated. An SiC fiber manufactured from an organosilicon polymer was used, and the combination of slurry impregnation and hot pressing was adopted in the present study. The method was improved so as to control...
