Investigation of Glass- Steel Slag Foam Composite Sintering in Presence of SiC
Amorphous steel slag was blended with different concentrations of waste glass (20, 40, 50, 60, 70 wt.%) and SiC to obtain a composite. According to Hot Stage Microscopy images, slag-glass composite contractions started at 1050 ºC. scanning electron microscope micrographs of slag-SiC (foaming agent) composite revealed tunnel-like porosities of 500 to 1000 microns. Gaseous products of carbide dec...
متن کاملSlag Hydration in composite cements
Despite reported synergies between alumina rich supplementary cementitious materials (SCMs) and limestone, previous studies have focused on up to 5% limestone content. Slag hydration in the presence of 10% limestone is reported in this paper. Hydration was followed through chemical shrinkage, calorimetry, thermal analysis, electron microscopy and X-ray powder diffraction. The results show that ...
متن کاملSteel Slag Utilization in Asphalt Mixes
Steel slags are the major byproduct from the conversion of iron to steel in the basic oxygen (major type), electric arc and open hearth (minor type) steelmaking processes. Steel recovery from the slag results in a processed aggregate with both positive (wear resistant, skid resistant, rough textured, angular, well graded, stripping resistant) and negative (heavy, expansive) features. Considerab...
متن کاملAccelerated Carbonation of Steel Slag Compacts: Development of High-Strength Construction Materials
Mineral carbonation involves the capture and storage of carbon dioxide in carbonate minerals. Mineral carbonation presents opportunities for the recycling of steel slags and other alkaline residues that are currently landfilled. The Carbstone process was initially developed to transform non-hydraulic steel slags [stainless steel (SS) slag and basic oxygen furnace (BOF) slags] in high-quality co...
متن کاملAbsorption of Lead Ions by Various Types of Steel Slag
Steel slags are the by products of steel industries, which forms during reduction process of iron melting. The chemical composition of it changes depending to the melting procedure. Its mineralogical composition also varies based on the cooling procedure. Two different types of steel slag were used as absorbing bed for various concentrations of Pb2+ ions in the form of lead chlor...
