lead slag aggregate
Use of Steel Slag Aggregate in Pavements Report November ...
Steel slag aggregate (SSA) is a byproduct of the production of steel in an electric arc furnace. The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense (SSA is 2030% heavier than naturally occurring aggregates such as basalt and granite).Get Price
USE OF FERROSILICATE SLAG FROM ZINC PRODUCTIOAS .
The slag typically contains zinc (912%), lead (12%), arsenic (05%) and copper (05%). ISF slag is inherently quite stable, retaining its physical characteristics over time. However, there is a concern that low level leaching of metals, in particular lead, could occur with prolonged exposure to water.Get Price

• Does Not Generate Alkaliaggregate Reactions • Blast furnace slag fine aggregate does not contain materials that may affect the strength and durability of concrete, such as chlorides, organic impurities clay and shells Slag Waste in Jordan Slag waste is a material resulting from the melting process of iron scrap or iron ore.Get Price
Characterization of the Zellidja Lead Smelter Slag ...
The Zellidja slag was derived from the extraction process of pure lead. After the preparation phase, consisting of the incorporation of agent of melting and raw material, lead sulphides (PbS) were transformed into lead oxides (PbO) after passing the set of agent and raw material through an elevated temperature fixed at 900°C.Get Price
AGGREGATES FOR SURFACE TREATMENTS
AGGREGATES FOR SURFACE TREATMENTS Description. Furnish aggregate for surface treatments in conformance to the type, grade, and surface aggregate classification (SAC) shown on the plans. Materials. Furnish uncontaminated materials of uniform quality throughout that meet the requirements of the plans and specifications.Get Price
Quenching the liquid slag (, granulation) on the other hand will generate a vitreous slag with latent hydraulic properties. All measures including processing of the solid and crystalline slag (, crushing and screening) is done to ensure that the produced aggregates and mixtures conform to requirements given in relevant European standards and regulations.Get Price

It may also be used in some lightweight concrete applications or products. The density of aircooled blast furnace slag is in the range of 1120–1360 kg/m3; expanded blast furnace slag coarse aggregate is in the range of 560–880 kg/m3; and the fine aggregate is in the range of 800–1120 kg/m3.Get Price
Utilization of Industrial Waste Slag as Aggregate in ...
said that full substitution of slag aggregate with normal crushed coarse aggregate improved the flexure and split tensile strength by 6% to 8% at all replacements and in case of replacing fine aggregate both the aggregates( Fine coarse) with slag, the strength improvement was at 30% to 50% replacements.Get Price

Slag Cement Questions
Blast furnace slag aggregate comes in two forms: Air cooled blast furnace slag, results when molten slag from a blast furnace slag cools slowly by ambient air (as opposed to rapid quenching), and is processed through a screening and crushing plant for use principally as a construction aggregate. Air cooled slag is not cementitious.Get Price
