	National Slag Association
		Blast Furnace slag has been called the "All-Purpose Aggregate" as it can be used in all construction applications as either a normal weight or lightweight (expanded or pelletized) aggregate depending on how it was formed and processed.
		Slags are produced in many metallurgical operations throughout the world and are considered a co-product of the production of iron and steel.
		Slag is an environmentally sound material that has been used to aid in the remediation of many environmentally damaged areas such as Acid Mine Discharge.

	Slag Cement Association - Slag Cement Creates Concrete At Its Best - Home
		For the second year in a row, a strong increase in portland blast-furnace slag blended cements helped total slag cement shipments for 2006 achieve record highs.
		Total slag cement shipments increased by 3.5% in 2006 to a total of 3.62 million metric tons.
		The Slag Cement Association (SCA) represents companies that produce and ship over 95 percent of the slag cement (ground granulated blast furnace slag) in the U.S. The SCA is the leading source of knowledge on blast furnace slag cementitious products.

	Ground Granulated Blast-Furnace slag (Site not responding. Last check: )
		The grade of a ground granulated blast furnace slag is based on its activity index, which is the ratio of the compressive strength of a mortar cube made with a 50 percent ground granulated blast furnace slag-cement blend to that of a mortar cube made with a reference cement.
		Use of slag or slag cements usually improves workability and decreases the water demand due to the increase in paste volume caused by the lower relative density of slag (Hinczak 1990).
		Effectiveness of slag in preventing damage due to ASR is attributed to the reduction of total alkalies in the cement-slag blend, the lower permeability of the system, and the tying up of the alkalies in the hydration process.

	Slag - Wikipedia, the free encyclopedia
		Ground granulated slag is often used in concrete in combination with Portland cement as part of a blended cement.
		Slag foaming is caused primarily by the generation of bubbles of carbon monoxide, carbon dioxide, water vapour, sulphur dioxide, oxygen, hydrogen gases within the slag, which foams much like soapy water.
		Foaming slag is also used in the smelting of copper, nickel, chrome and (experimentally) iron.

	Job knowledge for welders 43: Defects / imperfections in welds - slag inclusions (September 1999)
		Slag is normally seen as elongated lines either continuous or discontinuous along the length of the weld.
		Consequently, the risk of slag inclusions is significantly greater with basic fluxes due to the inherent convex weld bead profile and the difficulty in removing the slag from the weld toes especially in multi-pass welds.
		Short slag related imperfections are permitted in all three quality levels with limits placed on their size relative to the butt weld thickness or nominal fillet weld throat thickness.

	Steel Slag - Material Description
		The processing of steel slags for metals recovery is not only important to remove excess steel at the market source for reuse at the steel plant, but is also important to facilitate the use of the nonmetallic steel slag as construction aggregate.
		Steel slag destined for use as an aggregate should be stockpiled outdoors for several months to expose the material to moisture from natural precipitation and/or application of water by spraying.
		The slag processor may also be required to satisfy moisture content criteria (e.g., limit the amount of moisture in the steel slag aggregate prior to shipment to a hot mix asphalt plant) and to adopt material handling (processing and stockpiling) practices similar to those used in the conventional aggregates industry to avoid potential segregation.

	Slag: The ultimate renewable resource - Pit & Quarry
		Slag is poured from the furnace first as it floats on the surface while the heavier molten metal lies at the bottom of the vessel.
		In the Americas, blast furnace slag was available at the many iron furnaces that dotted eastern Pennsylvania because the raw materials — iron ore, limestone and charcoal from wood — were plentiful and easy to extract.
		Blast furnace slag began to accumulate into large stockpiles commonly known as "slag banks." In 1918, the National Slag Association was formed to unite slag producers to facilitate the promotion and recycling of this renewable resource.

	Slagging Furnace System/High-Temperature Air Furnace
		As the hot combustion gas leaves the slag screen, it is quenched with recirculated flue gas to 1850°F in order to reduce the stickiness of the ash, which reduces deposition on the CAH surfaces.
		Four slag injector feed ports and two view ports are located on the top of the furnace and hang into the furnace chamber.
		At the end of the transfer tube is a custom-designed feeder splitter to perform a 1-to-2-to-4-way split of the slag granules into the four feed injector entry ports, which are connected to the water-cooled stainless steel feed injectors.

		Primarily a compound of calcium and silica, slag also contains small quantities of uranium and radium these two elements are naturally present in the phosphate ore. Their presence in the slag causes it to emit very low levels of gamma radiation - a type of radiation similar to medical x-rays.
		They include: attrition, or removing the slag once the structure's useful life has ended; alterations in how the occupants use the area; and building additional living space to replace areas that contribute to elevated radiation doses.
		The primary focus of the phosphorus slag program is on gamma radiation from phosphorus slag that has been used as a building material in many area buildings.

	Coal Bottom Ash/Boiler Slag - Material Description
		Wet-bottom boiler slag is a term that describes the molten condition of the ash as it is drawn from the bottom of the slag-tap or cyclone furnaces.
		Boiler slag is essentially a coarse to medium sand with 90 to 100 percent passing a 4.75 mm (No. 4) sieve, 40 to 60 percent passing a 2.0 mm (No. 10) sieve, 10 percent or less passing a 0.42 mm (No. 40) sieve, and 5 percent or less passing a 0.075 mm (No. 200) sieve.
		When using bottom ash or boiler slag in an embankment, backfill, subbase, or even possibly in a base course, the potential for corrosion of metal structures that may come in contact with the material is of concern and should be investigated prior to use.

	What is a slag? (Site not responding. Last check: )
		The natural slag can be related to the metallurgical counterpart in that the silicates may be the predominant network component that form a glassy phase and usually contains a mixture of minerals.
		Metallurgical slags are also important as a vital part of the metallurgical process that made the industrial revolution feasible of the and the subsequent technical advances of the human civilization.
		Further, the slag functions mainly as a barrier to prevent the oxidation of liquid metal by the atmospheric oxygen and it serve as an ionic "buffer" to control the liquid metal composition.

	Footings mark major use of slag cement
		In May, Aucem GGBF slag cement -in a 70 percent substitution for Type II portland cement - was being used to lower the heat of hydration in a 2,600-yd.
		GGBF slag cement is not a new product, having been used for years in private sector construction, such as the high-profile Rock & Roll Hall of Fame in Cleveland, but still is undergoing the acceptance process among state departments of transportation (see "Waste" works wonders, Concrete Products, June 1996, page 50).
		GGBF slag cement has attributes such as a low heat of hydration, increased compressive and flexural strengths, inhibition of alkali-silica reactivity (ASR), resistance to sulfate attack, and reduced permeability to protect rebar from chloride penetration.

	Macro Slag (Site not responding. Last check: )
		Larger liquid inclusions (10 to 300 microns) occur due to emulsification of the covering slags or scums that are present on top of liquid steels and are generally due to practice related issues.
		Slag design is not an issue inthe removal of these macro-inclusions as dissolution of liquid inclusions into a liquid slag is not problematic.
		Therefore the onset of entrainment tends to be related to the sub-meniscus fluid velocity, the shear length (often related to slag depth) and the slag physical properties.
