Two different granulated blast furnace slags (GBFS) were supplied by two different Iron–Steel plants in northwest of Turkey. These slag samples were classified to be acidic slag (AS) and neutral slag (NS) based on their chemical compositions (Bauné et al., 2000). OPC (CEM I 42.5R) used in this study was obtained from Trabzon Cement Plant.

However, using sand made from blast furnace slag has serious potential to make concrete even better. Blast furnace slag fine aggregate received the JIS A 5012 certification in 1981. The Architectural Institute of Japan and Japan Society of Civil Engineers have also published guidelines on the use of this material. Today, this JIS certification ...

Iron production is via a continuous batch process with the iron and slag produced in the blastfurnace at a temperature around 1500ºC. The furnace is fed repeatedly with materials in a sequence of a 'coke dump', followed by a 'ferrous dump'. The 'ferrous dump' typically consists of a pre-blend of mainly sinter, but also graded lump iron ore and ...

Blast furnace (BF) slag is the principal byproduct formed during the iron-making process, which generates a considerable amount of thermal energy. However, to simultaneously recover the maximum amount of residual heat and obtain vitreous slag using a low conduction coefficient of air is a primary challenge of the dry granulation technique, which …

Basicity of titanium bearing blast furnace (BF) slag is critical for its crystallization behavior. Thermodynamics calculation indicates that rutile is the main phase after crystallization (or at room temperature). It precipitates during the cooling when the basicity of the slag is lower than 0.7. With increasing basicity, perovskite appears and becomes the main phase …

Blast furnace slag (BFS) is a kind of waste slag discharged from a blast furnace in pig iron smelting, and it is a kind of high-quality concrete admixture [16]. SiO 2, CaO, MgO and Al 2 O 3 are the main components in BFS, and the total contents of CaO, SiO 2 and Al 2 O 3 account for about 90%.

For both the waste treatment of large quantities of blast furnace (BF) slag and carbon dioxide (CO2) that are discharged in ironworks, mineral carbonation by BF slag was proposed in this decade. However, it has not been widely used due to its high energy consumption and low production efficiency. In this study, a m

In this section, we described the simulation of a 1.5-mm diameter molten slag particle at 1773 K with a velocity of 19.79 m/s impacting on the wall at 300 K, where we took the tangential velocity of the rotating cup [22] (cup diameter: 126 mm, angular velocity: 500–3000 rad/s) as the impact velocity of the molten slag particle. Fig. 4 displays the …

This research examines the chemical activation of blast-furnace slag pastes with alkaline solutions by means of various characterization techniques. Pastes were activated using sodium silicate solutions with modulus (Ms) of 0, 1, 1.5, 2, and Na 2 O at 5%, 10%, and 15%. Compressive strengths of up to 108 MPa were achieved for Ms = 1–1.5 …
