The primary applications for steel slag in the United States are its use as a granular base or as an aggregate material in construction applications. Disposal. While most of the furnace slag is recycled for use as an aggregate, excess steel slag from other operations (raker, ladle, clean out, or pit slag) is usually sent to landfills for disposal.
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace.
Through this research work, utilization of copper industry waste material called copper slag has been tried as a substitute of sand in fibre concrete containing 1% hook end steel fibres. The aspect ratio of steel fibre used in this work was 80. It was found that workability of fresh steel fibre concrete increased linearly on inclusion of copper ...
Jan 01, 2017· Steel slag is a by-product of the steel industry and can be used potentially as aggregate in asphalt mixture. This study evaluates the use of Steel Slag Aggregates (SSA) as substitute for natural aggregates in the production of hot mix asphalt (HMA) for road construction.
The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement. Blast furnace slag products have been used successfully in virtually all phases of bridge construction.
