METALLURGICAL USES FLUXES FOR METALLURGY

The function of the slag might vary at different stages within a process prior to final melting. For example, the slag composition and behavior will change as materials descend in the iron blast furnace, or as they melt in the early stages of formation of steel making slags. Selection of the chemistry for a slag might be in

Autogenous Deformation of AlkaliActivated Blast Furnace ...

28/04/2019 · Alkaliactivated slag (AAS) and AASC (alkaliactivated slag concrete) are made by activating granulated blast furnace slag (GGBS) with alkali solutions. The Portland cement can be replaced entirely, thus offering a substantially reduced environmental impact over conventional concrete. Concretes made with GGBS are less sensitive to earlyage thermal cracking due to .

Hydrothermal Synthesis of Zeolite A Using Blast Furnace Slag

Alkali hydrothermal synthesis of zeolite A using blast furnace (BF) slag was investigated. The preliminary experiment was conducted in use of synthetic slag consisting of SiO 2, Al 2 O 3, and CaO powders, and it was made clear that the most optimum slag compositions to synthesize zeolite A were the molar ratio of Si to Al (Si/Al) of 1 and reduction of CaO content down to 15 .
