In some studies, it has been demonstrated that using a composite mineral admixture known as ground-granulated blast-furnace slag-steel slag composite binder …
The process energy consumption of blast furnace ironmaking accounts for 45–60% of the total energy consumption of the iron- and steelmaking process, which is the key point of energy conservation in the iron and steel industry (Fig. 1).The energy input into the blast furnace ironmaking mainly contains coke, fuel injection, electricity, blast, …
Blast furnace slag (BFS) is a by-product resulting from the fusion of iron ore into pig iron, in a process carried out in industrial units called blast furnaces, where the oxides contained in the iron minerals are reduced and the impurities that accompany them are separated [].Slag is formed by the melting of impurities from iron ore after the …
1. Introduction. Blast furnace slag is a by-product produced from the iron-making process (Siddique and Bennacer, 2012).Statistically, approximately 300 kg molten slag is discharged per 1000 kg pig iron produced (Yuksel, 2018).Granulated blast furnace slag (GBFS) has different types according to the different cooling methods for the …
'slag' generally refers to ground, granulated, iron blast furnace slag – with the descriptors to be explained and developed in this technical note. In a general sense, the term 'slag' refers to a waste material separated from metals during the smelting or refining of an ore in a blast furnace. 'Slags' are formed during the smelting or
Granulated blast furnace slag (GBFS) is widely used in cement and concrete industries due to its excellent hydration properties. However, there is a huge capacity …
This paper presents experimental results and analysis of sulfate-bearing soils treated with ground granulated blast-furnace slag (GGBS). The experiments involve the unconfined compression strength test, shrinkage, free swelling, suction measurements, and microstructural examination.
