Regarding the generation of silico-manganese slag, between 0.9 and 2.2 tons of these slags are produced for each ton of silico-manganese ferroalloy manufactured [17]. In Spain, 162,086 tons of ferroalloy were produced in 2015, which confirms the high generation of the waste.

Ting M. et al. [16] used silico-manganese slag, seawater, and sea sand as raw materials to prepare concrete and evaluated the durability of the concrete. The results show that the use of sea sand can effectively improve the durability of concrete and has potential industrial application value. Due to the limitations of concrete products, the

Standard silicomanganese with 18-20 % Si and about 70% Mn is produced from a blend of HCFeMn slag with about 35 to 45% MnO, manganese ores, quartzite, (Fe)Si-remelts or off grade qualities, and coke. Sometimes minor amounts of MgO-containing minerals are added, e.g. dolomite [CaCO3⋅MgCO3] or olivine [(MgO)2⋅SiO2].

MgO facilitates fluid silicomanganese slag but would make ferromanganese slag viscous. Al 2 O 3 makes silicomanganese slag fluid at Al 2 O 3 content with 0.41 …

When molten silicon manganese slag contacts with water, it is cooled down rapidly with much water vapor and to be a rock masses like as volcano rock. This porous …

This paper reviews the potential use of silico-manganese slag (SiMnS) as binder and aggregate in Portland cement and geopolymer concrete. SiMnS is a byproduct of alloy steel production.

The properties of a welding flux based on the silicomanganese slag are investigated. The flux is produced using the slag formed in the production of silicomanganese with different ratios of the ...

In this study, silico-manganese (SM) slag was dried, ground into powder, and used as raw material. Solid and liquid alkaline activator methods were used to prepare SM slag non-burning aggregate (SMNA) by the cold bonding method. The effects of grinding time, amounts of solid and liquid alkaline activators, curing temperature, and the …

The literature on the use of silico-manganese slag in alkali-activated material is still limited, but there has been an increase in the number of research papers over the years, reflecting a growing interest and attention of researchers towards this area.
