Once the slag has been cooled and ground to a usable fineness it is stored and shipped to suppliers throughout the United States. Slag cement is commonly found in readymixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products.
The lead containing components are processed in blast furnaces for hard lead or rotary reverberatory furnaces for fine particles. The blast furnace is similar in structure to a cupola furnace used in iron foundries. The furnace is charged with slag, scrap iron, limestone, coke, oxides, dross, and reverberatory slag. The coke is used to melt and ...
Phosphorus Slag. Phosphorus slag has been used as an aggregate substitute in hot mix asphalt, as a lightweight masonry aggregate, and as cement kiln feed. Granulated phosphorus slag has also been used experimentally in the production of a blended cement product. (4) Lead, LeadZinc, and Zinc Slags
Secondary lead slag, a waste product from battery smelting using CaCO 3 as flux, has been investigated for its use as an admixture and/or aggregate in the production of concrete blocks. The slag was added as partial replacements of cement and/or aggregate. The results revealed that the oxide components of the slag were similar to those of ordinary Portland cement (OPC).
The use of steel slag as a cementing component should be given a priorityfor technical, economic, and environmental reasons. While slag cement use is miniscule in contrast with portland cement use, it has been around for a while. In fact, it was used in the building of both the Paris underground system and the Empire State Building.

It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer.
A nonferrous slag from the production of metallic zinc was studied as a new ingredient for concrete. It was used in two forms: ground and unground material. The ground slag replaced 15% of portland cement, whereas the unground slag replaced 20% of the natural sand.
Blast furnace slag products have been used successfully in virtually all phases of bridge construction. Projects such as the bridge pictured here can utilize blast furnace slag as a concrete aggregate. Blast furnace slag has been utilized in concrete masonry for many years.
though sodium slag contains lead (approximately 5 wt. %), soluble alkalis and decomposes in contact with air, Na2CO3 is mainly used in industry due to generated amount of total slag, as well as reduced energy and gas consumption [4]. Secondary lead slag is characterized as hazardous waste in European Waste Catalogue due to content of
