Natural aggregates are becoming increasingly scarce and their production and shipment is becoming more difficult. It is also successfully used as an aggregate for concrete. Furthermore, BOF slag and EAF slag are used in asphaltic mixes and road-base layers. The iron and steel slag used as aggregates for asphalt roads are iron and steel by-products. The air cooled BF slag is either dumped as landfills or used in road repairs within the steel plant. With high particle density and hardness, this slag has superior wear resistance and for this reason is used as an aggregate for asphalt concrete. <>>> In other words, aggregates are used as a stable foundation or road/rail base with predictable, ... and steel furnace slag sold or used in the U.S. was 8.7 million tonnes valued at $40 million. Granulated slag forms sand-sized particles of glass and is primarily used to make cementitious material. 18. Applications were quite sporadic until the last century, when large quantities began to be used for a number of purposes.

Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys.Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. . application of slag is possible in different road layers. It also minimizes any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal. A small amount of BF slag gets air cooled. Expansion inhibition of steel slag in asphalt mixture by a surface water isolation structure. All slag is crushed, screened and graded to specific sizes. Materials: CBR of 15%; Passing through 425 micron IS sieve; L.L<25 and P.I<6; Waste material such as Fly ash, Iron and steel slag Recycled concrete Municipal waste are also used. Steel slag is a by-product of the steel industry and can be used potentially as aggregate in asphalt mixture. In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense ready-mixed concrete. A comprehensive study was conducted to characterize SSA and determine the potential for its use in road bases. It is eco-friendly because weare doing waste manag e-ment. Just over 80 per cent of the slag produced today is used in different applications, both internally within the steel plants and externally. • Since slag is fails in abrasion test it can’t be used in the surface course.

Aiban, SA Associate Professor, King Fahd University of Petroleum and Minerals, Dhahran. Steelmaking slag Because of its hydraulic property and the large bearing capacity it can provide, steelmaking slag is used as a road base course material. Basic Use:Aggregates are used for base and subbase road construction. Steel slag as aggregate has many well-known applications in road construction such as, hot mix asphalt, cement concrete mix, antiskid-layer, granular-base and subbase layers. in road construction industries is gradually gaining significant importance in India, in light of the disposal, environmental problems and gradual depletion of natural resources, such as soil and aggregates. steelmaking slag for road base course use. Steel furnace slag sales in 2006 were for use in road bases and surfaces (51%), asphaltic concrete (12%), for fill (18%), and the balance for other uses. Dermal contact with EAF slag occurs in many occupational and environmental settings because it is used widely in construction and other industrial sectors for various applications including asphaltic paving, road bases, construction fill, and as feed for cement kilns construction. Mainly as a granular road base or as an aggregate in construction applications, steel slag aggregate (SSA) has been successfully used in the Middle East under hot weather conditions [ 24 ]. Steel slag SMA has high temperature stability. Like other metallurgical slags, steel slags exhibit a great potential to be used as aggregate in highway construction. The aggregate formed from the slag is comprised of calcium oxide (CaO), silicon oxide (SiO 2), iron oxide (Fe 2 O 3 Slag has lighter CBR value than fly ash and hence saving in excess than fly ash use.

Almost all GGBFS is used as a partial substitute for portland cement in concrete mixes or in blended cements. Advantages of LD slag in road construction. The slag produced is very angular and porous with a rough surface texture (Figure 1). This leads to reduction of landfills reserved for The subbase of this road was constructed from steel slag. Ing. It also contains phosphorous, calcium, ash, remnants of flux materials such as limestone, and remainders of chemical reactions between the metal and the furnace lining. Steel Furnace Slag Aggregate tecHNIcAL Note 09 INTRODUCTION This Technical Note provides information on the properties of steel furnace slag aggregate and potential uses in roadworks. Although the construction industry does use some slag as an aggregate, most is simply discarded. The practical application of the LF slag differs from the … Slag is a sustainable product that can be recycled and reused multiple times. Slag has a greater PSV (Polished Stone Value): i.e., greater resistance to wear. 4.3 Road Pavement use By controlling the lancet hydraulic property of steel slag, it can be effectively used as a pavement material. Duraberm, which is made from steel furnace slag, is a strong and sustainable material that holds up under heavy truck traffic, provides long service life, and helps control project cost.
