Abstract:

Abstract The construction industry is pursuing the reduction of CO2 emissions and the development of lowcarbon concrete. LOIKKA research project was initiated in Finland with the aim to reduce the CO2 emissions of concrete manufacturing by 50%. The use of blast furnace slag was seen as the most competitive way to significantly reduce CO2 emissions of concrete. However, incorporating slag in concrete can lead to durability complications, particularly concerning salt freeze-thaw resistance. This study investigates the effects of slag content, carbonation/ageing, and pre-curing conditions on the

Abstract:

Electric arc furnace slag (EAFS) and ladle furnace slag (LFS) are by-products of the electric steelmaking sector with suitable properties for use in bituminous mixtures as both coarse and fine aggregates, respectively. In this research, the production of a porous asphalt mixture with an aggregate skeleton consisting exclusively of electric steelmaking slags (using neither natural aggregates nor fillers) is explored. The test program examines the asphalt mixtures in terms of their mechanical performance (abrasion loss and indirect tensile strength), durability (cold abrasion loss, aging, and lo

The effect of phase composition and microstructure of Al4SiC4-Al4O4C composite refractories after sintered and immersion in the slag on its slag resistance was preliminary investigated.

While the refractories synthesized at 1800 °C presented better slag resistance because the dense microstructure and higher Al4SiC4 content inhibited the slag penetration and corrosion.

However, in numerous numbers of recent researches it has been observed that there is a possibility of consuming this industrial steel slag as alternate to any of the fine and coarse aggregates in normal or conventional concrete mixes.

Abstract:

The effects of varying the additions of magnesium aluminate spinel (0, 3, 6, 9, 12 wt. %) on the physical properties and slag resistance of Al2O3-SiC-C based castables were investigated. The composition of the specimens was determined by X-Ray diffraction (XRD). The results revealed that the incorporation of appropriate amount of MgAl2O4 in Al2O3-SiC-C based castables could promote the sintering of the specimens, decrease apparent porosity, and improve bulk density and strength. The slag resistance of the castables was improved due to an increase in the viscosity of molten slag, caused by the

Abstract:

Copper smelting slag usually contains 1–6 wt% copper, which can be recovered by pyrometallurgical and flotation processes. However, the tailing slags still consist of 0.3–0.7 wt% Cu and 35–45 wt% Fe equivalents to those in the copper and iron ores, respectively. Most of the research was focused on the recovery of iron from the tailing slags. Copper can increase the mechanical strength, corrosion resistance and antibacterial property of some steels. A new process to recover copper and iron directly and fully from hot copper smelting slag is proposed to produce Cu-Fe alloy for steel production.

Stone mastic asphalt is a type of hot mix asphalt that requires much coarse aggregate, so substitution waste aggregate, such as steel slag, will be an economic reason. The problem is that there are still many things that have not been consistent in various studies related to the moisture resistance of steel slag. The study aimed to compare the effect of Ca(OH)2 on the moisture resistance of the steel-slag stone mastic asphalt mixture and to determine the optimal Ca(OH)2 dosage for improving the mixture resistance.

To improve the properties and RH degasser slag corrosion resistance of magnesia-chrome refractory, the effect of the addition of ZrO2 was investigated. The results showed that the presence ZrO2 additive can densify the magnesia-chrome samples due to promotion of grain boundary activities and ultimately direct bond formation, which improved the high temperature mechanical properties and corrosion resistance. The results also indicated that in the RH degasser slag system with a high ratio of calcia to silica, the slag resistance behavior of magnesia-chrome composite added ZrO2 could be described
