In present research, the foam glass-ceramic composites fabricated by window glass, steel slag and SiC, CaCO3 foaming agents were investigated by press–sintering method. The optimum sintering temperature was obtained at 1200°C with a 3-minutes holding time and 20°C/min heating rate. The optimum pressure level of 80 MPa for achieving the 70 % of relative density was selected. The effec...

Non-metallic inclusions (NMIs) in steels have been the focus of various experimental studies due to their detrimental character. While isolated processes, such as agglomeration or dissolution, well investigated, holistic in-situ views with high-temperature confocal scanning laser microscopy (HT-CSLM) rare. In this work a novel and suitable method is presented simultaneously observe agglomeratio...

EPA has completed a substantial study to re-evaluate use of the presence of slag wool fibers as a potential marker for World Trade Center (WTC)-derived dust contamination. Slag wool is an insulating material (made from blast furnace slag) that was used in the construction of the WTC. Large quantities of slag wool were released into lower Manhattan by the collapse of the WTC. Samples of dust col...

Nowadays, magnesia carbon refractories are very important for the iron and steel industries. It is due to their unique properties, such as low wet ability with melt iron and steel. Therefore, it is important to extend the life of the refractory. In this research, the effect of calcined alumina and nano carbon on mechanical strength and corrosion resistance against slag in magnesia carbon refrac...

To reduce CO2 emissions from the building industry, one option is to replace cement in specific applications with alternative binders. The Carbstone technology based on reaction of calcium- and magnesium-containing minerals form carbonate Mixes carbon steel slag stainless-steel slag, tailored particle size distributions, were compacted a vibro-press subsequently carbonated an autoclave produce ...

Steel is mainly produced through continuous casting; molten steel flows into the mold from tundish, where it cools and then enters secondary cooling zone, ultimately solidifying a billet. During casting production process, quality of billet related to lubrication state coated slag. In upper part mold, consumption liquid protective slag directly affects friction initial solidified shell. Therefo...

This study presents the result of using melting to recover both industrial sludge slag (the main constituent of which is calcium fluoride) and water works sludge slag as fine aggregate in cement. The main characteristics of both slag and cement mortars were measured to evaluate the feasibility of using slag as aggregate. In this study, the slag replacement ratios were 0, 10, 20, 30, 40, and 50%...
