Mineral carbonation is a method in carbon capture and utilization (CCU) which dioxide reacts with natural or synthetic mineral phases to form carbonates. In this study, BOF slag consisting of alite, Ca3SiO5, belite, Ca2SiO4, melilite, (Ca,Na)2(Mg,Al)[4][Si2O7], brownmillerite, Ca(Fe,Al)2O5, calcium ferrite, Ca2FeO4 Ca-, Mg- Mn-bearing wuestite, (Mg,Ca,Mn,Fe)O, was crushed into different particl...

CaF2 has a significant effect on the viscosity of CaO-SiO2 slags, which is closely related to change melts structure. In this study, molecular dynamics simulation been used study influence different adding methods short-range and medium-range melt structure CaO-SiO2-CaF2 at 1823 K. The results show that directly slags ((50-x/2)CaO-(50-x/2)SiO2-xCaF2, x = 5 ~ 20 mol%), distribution oxygen types ...

Many phenomena in continuous casting including the formation of surface defects are greatly affected by heat transfer in the mold. The interfacial slag layers between the solidifying steel shell and the mold wall dominates the resistance to heat removal and thus controls mold heat transfer. Surface defects, such as longitudinal cracks and star cracks have been associated with variation of slag ...

The scope of this study focuses on the use two different types industrial byproducts such as slags (FeNi and Electric Arc Furnace slag) combined with natural sand concrete aggregates well evaluation their suitability final physicomechanical behavior produced specimens. For reason, twelve specimens were prepared using variable concentrations these which compared to made by rocks (limestones). mi...

Ceramics and glass ceramics based on industrial waste have been widely recognized as competitive products for building applications; however, there is a great potential for such materials with novel functionalities. In this paper, we discuss the development of magnetic sintered glass ceramics based on two iron-rich slags, coming from non-ferrous metallurgy and recycled borosilicate glass. The s...
