Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnac The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling
Iron and Steel Slag Statistics and Information Iron and steel slags are coproducts of iron and steel manufacturing In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent
Sometimes, effects similar to those achieved through the addition of admixtures can be achieved by altering the concrete mixture-reducing the water-cement ratio, adding additional cement, using a different type of cement, or changing the aggregate and aggregate gradation Five Functions Admixtures are classed according to function
ground granulated blast furnace (GGBF) slag was reported as early as 1774 GGBF slag has been used in concrete in Japan and Western Europe since the 1940s Concrete containing slag is estimated to comprise approximately 20 percent of the hydraulic cement produced in Europe Blast furnace slag is used predominately as base and concrete aggregate .
The concrete industry's greater acceptance of mineral additives such as fly ash and blast furnace slag will drive demand for these products as partial substitutions for portland cement The increase also is a result of higher-value formulations in additives such as water reducers, accelerators, and air entrainers
about $104 for some 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
Adding GGBFS during cement production can increase the strength 28D of cement by 15% - 20%, to admix 425 grade cement, and during concrete production, slag powder can replace 10 ~ 50% of the cement, to mix C20 ~ C60 concrete, which has become an important measure to reduce the cost of cement in the international cement industry
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 20-30% heavier than naturally occurring aggregates such as basalt and granite)
