slag GGBFS. Air-cooled iron slag and steel slag are used primarily as aggregates in concrete air-cooled iron slag only asphaltic paving, fill, and road bases both slag types also can be used as a feed for cement kilns. Almost all GGBFS is used as a partial substitute for portland cement in concrete mixes or in blended cements.
Cement kilns. by injecting steel slag into cement kilns, txi has seen a 10 increase in production with no plant expansion, no additional co 2 emissions and no additional energy require-ments. each ton of slag produces an additional ton of clinker, the main ingredient in portland cement. steel slag that once sold for 3 to 8 a ton is now
It is is produced by the steel production industry. slag happens when iron ore is melted. the molten iron sinks to the bottom, while the slag will float on the top of the iron. see the diagram below another difference between slag and fly ash is that while fly ash will rarely surpass 35 of the cement content, slag can substitute 50 of the ...

Iron and steel slag products are used in a variety of areas where their unique characteristics are put to effective use. the majority of the demand for these products comes from the field of cement. approximately 40 of iron and steel slag products, and 60 of blast furnace slag, are used in cement.
The cement industry can easily use bulk rice husk from mills as kiln fuel, though transportation and storage may cause problems. rice husk has one more advantage for the cement industry. rice husk, after burning, produces about 20 ash. rice husk ash has high pozzolanic activity, and so can easily be used to produce good quality blended cement.
James g. speight phd, dsc, in asphalt materials science and technology, 2016. 126.96.36.199 slag. slag aggregates are obtained by crushing of smelter slag or by special treatment of fire-liquid slag melt molten slag aggregates. currently there are many types of concrete that are developed and used in construction that include metallurgical slags both as a binding component and as fillers.
