	Slurry wall - Wikipedia, the free encyclopedia
		A slurry wall is a type of wall used to build tunnels, open cuts and foundations in areas of soft earth close to open water or with a high ground water table.
		The hole is kept filled with slurry (a mixture of bentonite and water) at all times to prevent collapse.
		Slurry wall construction was the type used to construct the "bathtub" that surrounded most of the World Trade Center site.

	International Slurry Surfacing Association
		Slurry seal is applied to an existing pavement surface by means of a spreader box linked to the surface slurry-mixing unit.
		Slurry is introduced into the spreader box, which then lays down the slurry coating as the mixer/spreader is driven forward.
		The box is capable of spreading the slurry seal over the width of a traffic lane in a single pass, and is constructed so that close contact with the existing surface is maintained.

	Slurry Seals (Site not responding. Last check: 2007-10-22)
		Slurry Seals were used for the first time in Canada in the 1960s and their usage has exponentially increased across Canada where approximately 3.5 million square metres are now placed every year.
		Slurry Seals are properly proportioned mixtures of unmodified cationic emulsified asphalt, mineral aggregates, mineral filler, water and additives which are mixed and spread with a machine over a properly prepared surface.
		Surface slurry sealing systems are surface treatments that provide protection of the pavement surface by delaying the appearance of surface defects caused by both the environment and the associated oxidization of the existing surface.

		Slurry pipelines are used to transport aggregate materials by embedding them in a fluid, usually water.
		At the end of the pipeline, the material is dehydrated, and the aggregate is thus available.
		Typical materials that are transferred using slurry pipelines include coal, copper, iron, and phosphate concentrates, limestone, lead, zinc, nickel, bauxite and oil sands.

	Graniterock: Technical Note - Slurry Seal Emulsion
		A slurry seal is a mixture of well-graded fine aggregate, mineral filler (if needed), emulsified asphalt, and water applied to a pavement as a surface treatment.
		The slurry machine has a continuous-flow mixing unit, either single or double pugmill, from which the slurry is discharged into a spreader box.
		Slurry should be placed only when the temperature is at least 10°C (50°F) and rising and when no rain is expected.

	Drilling Waste Management Fact Sheet: Slurry Injection of Drilling Wastes
		Liquid is added to the solids, and the slurry (or the oversize material) may be ground or otherwise processed to reduce particle size.
		Slurry injection relies on fracturing, and the permeability of the formation receiving the injected slurry is a key parameter in determining how readily the rock fractures, as well as the size and configuration of the fracture.
		When the slurry is no longer able to move through the pore spaces, and the injection pressure continues to be applied, the rocks will crack or fracture.

	Slurry Seal Frequently Asked Questions
		Slurry seal is a petroleum-based emulsion product, mixed with fine aggregate rock, blended on-site in a large truck, and then applied evenly across the entire surface of an asphalt street.
		A slurry seal is typically 1/4 to 3/8 of an inch thick.
		During the slurry seal application, access to your street will be interrupted for a maximum of 6 hours, one day only, unless the contractor is delayed due to equipment failures, weather-related problems, or other unforeseen reasons.

	MTA - Slurry Walls
		"Slurry" refers to a clay-water mixture that is pumped into the excavation for the wall to keep the sides intact until concrete is poured in.
		The clay-water slurry mixture was just heavy enough to keep the walls of these very deep excavations intact before huge reinforcing steel beams were lowered into the trenches and concrete pumped in to fill the hole.
		Slurry walls were essential to the success of the Central Artery project because the special excavating equipment can work in confined spaces in a dense old city such as Boston (the machinery was first developed in Europe), particularly under the elevated highway where there was no headroom for tall conventional excavators.

	Development and Characterization of Soil-Cement Slurry
		Abstract Soil-cement slurry is a combination of soil, Portland cement, and adequate amount of water so that the mixture has the consistency of a thick liquid.
		Compressive strength tests and flowability tests were performed to assist in the design of the soil-cement slurry mix and to serve as the control technique during construction.
		To study the mechanical behavior of the slurry, specimens of different mix were tested and the compressive strength and flowability were related to specimen mixtures.

	Preparation of high performance silica slurry using a centrifuge - Patent 6802983
		The slurry and material removed from the semiconductor wafer during a polishing process form a waste stream that is commonly disposed of as industrial waste because reuse of the polishing slurry that contains large-sized polishing refuse or aggregation may cause damage to the polished surface.
		The flow of the polishing slurry through the system, whether previously used or not, is conducted by flowing the aqueous slurry from the slurry tank 14 through the filtering device 10 and into the centrifuge 12 at a pressure of about 0.01 to about 0.5 MPa.
		The aqueous slurry, after passing through the filtration device, is then introduced into a solid bowl, sedimentation-type centrifuge, such as disc-nozzle centrifuge 12 wherein the aqueous slurry is subjected to centrifugal forces for separation and removal of abrasive particles greater than 0.5 microns.

	Solid State Technology - Optimum process performance through better CMP slurry management
		CMP slurries are primarily aqueous-based complex suspensions containing silica, alumina, or ceria abrasive particles, and chemical additives such as oxidizers, polymers, pH stabilizers, dispersants, and surfactants.
		Before new slurry containers are connected to a blending and distribution system, one must ensure that the system has been thoroughly cleaned and that all residual slurry particles have been removed.
		Recirculation may cause shear to the slurry due to sudden changes in cross-sectional area and direction of the flow path, and pressure fluctuations in pumps, valves, and fittings causing premature aging of the slurry.

	logos: Ice-slurry technology may reduce the effects of heart attacks
		The team was recently awarded a five-year grant for nearly $4 million from the National Institutes of Health to expand the medical applications of ice slurry — a mixture of ice and salt water that may be injected into the lungs for rapid cooling to sustain the heart and brain cells after cardiac arrests.
		Ice slurry is an equal mix of ultra-small (equivalent to the diameter of a human hair) ice particles and a salt water liquid carrier.
		Researchers reasoned that by filling the lungs with the ice slurry and maintaining chest compressions, the blood supply to the brain would be chilled and would slow cell activity and death.

	PSI - Pipeline Slurry Design (Site not responding. Last check: 2007-10-22)
		Slurry pipelines have an aesthetic advantage, in addition to commercial advantages, over other modes of solids transportation, as nearly all facilities are buried and out of sight with only a few widely separated surface structures.
		Some of the main factors which affect the economics of a slurry transport system are the tonnage and distance transported, existing infrastructure, physical characteristics of the solids, and terrain conditions along the right-of-way.
		There are also tests to determine the abrasivity of the slurry to mechanical equipment such as pump parts, and tests to define the pipeline operating conditions, including restart after system shutdown.
