Precautionary treatment was practised at the steel plant to reduce the free CaO/MgO content of steel slag before use as aggregates; and mandatory leaching test twice a year was required for use in roads and hydraulic structures (Motz and Geiseler, 2001). European standard permits the use of steel slag in asphalt provided the 7 days volumetric expansion is no more than 3.5% (BSEN13043, 2002). 4 ...

SFS aggregates are therefore not commonly used in concrete, although SFS aggregates have been used as a high quality frictional aggregate for hot-mix asphalt (HMA) surface courses. The resultant fractionated reclaimed asphalt pavement (FRAP) when the HMA with SFS is removed has also seen little usage. This study aims to continue the previous work by the authors that indicated that up to 50% ...

An extensive experimental analysis was done to find the various strengths of steel slag, eg, when used as aggregates in roads. The objective of this chapter is to identify the mechanical characteristics of steel slag for using it in the construction of roads, which will be helpful to replace natural aggregates. As slag is an inert material, it cannot take part in chemical reactions during ...
