Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Iron and steel slag used in road construction is manufactured by crushing and mechanical stabilization of blast furnace slag and steelmaking slag for use as paving material. Use of Blast Furnace Slag in Road Construction 23. Many researchers have investigated the use of steel slag as an aggregate in the design of asphalt concrete for the road construction. Looks like you’ve clipped this slide to already. Steel slag waste material for the construction of road. For the hundred percentage replacement of steel slag, it requires only the transportation charges. The research covers the construction and fiveyear performance of a pavement constructed with 30% steel slag. Slag Aggregates in Asphalt Applications An ideal aggregate for base, binder and surface course asphalt products, the inherent properties in steel slag are assessed in accordance with the requirements of the European standard EN 13043 and can produce asphalt materials exhibiting superior properties to those manufactured with primary aggregate. The most common use is as an aggregate in the manufacture of asphalt. This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminous paving mixtures. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Steel slag has been used in asphalt for over 80 years in the UK It reduces the need to quarry helping preserve our natural resources Longer lasting roads means reduced costs and reduced environmental impact As global environmental policies are reviewed, steel slag presents an 2. -v;Û/ÊùuáÍîz³(æÈHÓ˂êï×3"ƏëÙ7\!>Ùßâ§ýõc¯ã¢Ûq ƒ¦å¸Àä¥E•åáÿ4?û훋Ÿ­Ö]ÍЦÊJ=q ‹“.S¤UžéßçïpŒßá˜ÿ Fø÷̖šËŲž«>™—F‰ÞDI5m”ÉT§GyŽ™bÊ°Sgù‰ù;8VªÌ4¨CQfF2Xdº®0èÃÚQáÀô¾?UÉ1,óLÅ-ÿ8ÿÛb) Steel slag is residue from the steelmaking process, made of minerals like silica, alumina and titanium from iron sand, and combinations of calcium and magnesium oxides. Qatar: The Ministry of Municipality and Environment (MME), the British Transport Research Institute (TRL), Qatar Steel and Ashghal have been running a pilot project to use steel slag in the construction sector including to build roads. There are many possibilities for using metallurgical slag in the construction of road pavements. Despite this, a large amount of steel slag generated from steel industries is disposed of in stockpiles to date. A., & Production, A. S. S. (2015). Now customize the name of a clipboard to store your clips. Usage in road and hydraulic construction – Steelmaking slag can be processed to aggregates of high quality comparable with those of natural aggregates because of its high strength and durability. ROAD CONSTRUCTION The coarse and fine aggregates shall consist of hard, tough, durable pieces of steel slag, and shall be processed, as necessary, by crushing or screening, or both, and magnetic separation for the removal of metallics. Steel slag is a by-product of the steel industry and can be used potentially as aggregate in asphalt mixture. The utilization of waste materials, such as coal ash, copper slag, steel slag, jarofix, zinc slag, etc. Steel slag aggregate (SSA) is a byproduct of the production of steel in an electric arc furnace. As a result, a large area of land is being sacrificed for the disposal of this useful resource. bituminous road surface bituminous roadways what is bituminous pavement bituminous asphalt define bituminous pavement bituminous concrete vs asphalt bituminous surface course bituminous surface treatment uses for steel slag types of slag steel slag for driveways steel slag asphalt metal slag uses steel slag aggregate steel slag price steel slag waste interesting civil engineering topics seminar topics pdf civil engineering topics for presentation civil seminar topics ppt best seminar topics for civil engineering seminar topics for mechanical engineers civil engineering ppt latest civil engineering seminar topics. A Pennsylvania Department of Transportation study found that bituminous mixtures containing steel slag exhibited high stability, high skid resistance, and longer heat retention resulting in … MATERIALS USED The performance was studied of three types of bituminous mixtures for road construction: 1. Steel slag as aggregate has many well-known … 1. To improve its Geotechnical engineering properties, the Steel Slag … Slag is typically received in pots from steel furnace refining vessels contaminated with metal that separates to the bottom. Abstract and Figures Steel slag is a byproduct from steelmaking industry and has been recycled in many countries around the world for decades. Electric arc furnace slag (EAFS) is a co-product of steel making process. The research focused on the use of different types of slag in road construction in Ukraine. The best management option for this by product is its recycling. 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). use of alternative materials in road construction. Slag use is subject to strict regulations and standards. Many researchers have investigated the use of steel slag as an aggregate in the design of asphalt concrete for the road construction. There are strong practical implications for both practitioners and academicians for using steel slag in the construction of roads. An ambitious road construction plan is underway in India, which primarily involves bituminous pavements. Steel slag is a product of much importance for road construction, successfully substituting natural materials. ˜E03Ëù¶ùýæfž(/D‘E\^cs¨$ŸßßÓôn~U!Éz@re‡“¢e-dL›êŸ ¢² As a result, a large area of land is being sacrificed for the disposal of this useful resource. See our Privacy Policy and User Agreement for details. Specifically, Siam Steel Mill Services Ltd. provides the management of EAF slag in terms of handling, metal recovery and crucially the production of a quality slag aggregate for use in road construction. Zumrawi, M. M. E., Khalill, F. O. To achieve sustainable development, use of steel slag as a substitute to natural-aggregates has gained significant attention. The iron and steel slag used as aggregates for asphalt roads are iron and steel by-products. 1. In particular, the focus of the guidelines is minimization of the risk of environmental contamination. 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. Production and application of steel slag coarse aggregate in asphalt mixture @article{ZhaoMeiling2017ProductionAA, title={Production and application of steel slag coarse aggregate in asphalt mixture}, author={ZhaoMeiling and WuShaopeng and ChenZongwu and Lichao}, journal={Emerging Materials Research}, year={2017}, volume={6}, … 1.1 This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminous paving mixtures.
