Blast-Furnace Slag as a Mineral Admixture for Concrete
Finely ground slag may be blended with portland cement or added to other ingredients at the mixer. When slag, a by-product of the iron-making process, is quenched with water and rapidly chilled, it forms a glassy granulated material of sand-like consistency. Because of its high calcium silicate content, it has excellent cementitious properties.

What is Electroslag Welding in Welding?
Electroslag welding is a process that produces the coalescence of metals with molten slag. This process melts the filler metal and the surfaces of the work to be welded. The molten weld pool is shielded by the slag, which moves along the full cross-section of the joint as welding progresses. This type of welding is used for welding …
What is Slag in Welding, and How Does It Work? (2024 …
Slag is the byproduct of some arc welding processes. It is formed during welding from flux. When the arc initializes and is stabilized, the filler metal of the electrode begins to liquefy and is deposited into the weld zone. Since the molten metal is fluid and has not cooled, it is much more prone to obtaining defects during the welding process ...
Slag
Molten slag is carried outside and poured into a dump. Slag is a by-product of smelting (pyrometallurgical) ores and recycled metals. Slag is mainly a mixture of metal oxides and silicon dioxide.Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by …
