2021-6-21  Furnace slag used in this research is shown in Fig. 1(a), its density is 2250 kg/m 3.With the function of filter, the particle size of sub-ballast needs to stay in a range of Particle Size Distribution (PSD), which is shown in Fig. 2.So, the slag was sieved and remixed, and the PSD curve is also shown in Fig. 2.In comparison, the traditional sub-ballast is granite material, i.e. the crushed

Vertical load distribution in ballasted railway tracks

Vertical load distribution in ballasted railway tracks with steel slag and limestone ballasts. Over the last few years, use of steel slag ballast as an appropriate material instead of conventional stone ballast has gotten more attention by railway owners in various countries. In this regard, one of the technical concerns is the differences of

Analysis of carbonation and hydration of BOF steel slag

The use of BOF steel slag as aggregate or rail ballast material is hampered by the possibility of volumetric expansion. These expansive reactions occur involving certain compounds present in the steel slag, generating internal stresses that cause cracks and even result in the fragmentation of the material, in a destructive expansion.

Recycling our waste ArcelorMittal

One of these is Linz-Donawitz (LD) slag. At a major steel unit, such as the one in Tubarão, Brazil, we produce as much as 800,000 tonnes of LD slag every year, and ArcelorMittal has been researching ways to re-use this material. After a comprehensive study of its properties, we now make as many as 30 new products from LD slag.
