Jun 29, 2017· Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers'' current waste footprint.
steel slag is mainly used as road aggregates; however the problems related to its volumetric instability and lack of studies that explore the engineering properties of steel slag have impeded the utilization of steel slag in other applications in construction industry, specifically for the finer fraction (sand and siltsizes ) of steel slag.
As far as the usage of LD slag is concerned, per cent was used in 200405. These were primarily used as flux material at Tata Metallics Limited, used in sinter production and in mini cement plants. On the other hand, all the dust and sludge, which originate from various points in the processing of iron and steel was used.
used in road construction in Roman times. Steel industry has been a pioneer for the recycling, due to the high recycling rate of scrap, and the early use of slag products. Nowadays, owing to the intensive research work during the last a few decades, of iron making slags are being reused in most countries, and utilization rate of steel slags
