Properties of TiO2 powder got hydrometallurgically from the slag that was, together with pig iron, a product of reductional red mud electromelting were investigated using physico-chemical methods of analyzing. The samples of TiO2 powder contain high quantity of titanium compared with the used raw material granulated slag. Investigating the mophology of the powder samples, it has been found out ...

In this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. For this reason, various experimental parameters such as pH, contact time and the primary ion concentration were investigated. The remaining concentrations of ions such as; Mn2+ and Fe2+ in water were measured by atomic adsorption spectroscopy. The chemical and p...

In the current work, the properties of cement pastes doped with high amounts of ground granulated blast-furnace slag (HVS) were investigated. Portland cement (PC) was substituted with ground granulated blast-furnace slag (donated as slag) at very high amounts of 85%, 90%, 95% and 100%, by weight. PC paste without any content of slag was used as a reference. Some fresh and hardened properties su...

Inhalation exposure models are becoming the preferred method for the comparative study of respiratory infectious diseases due to their resemblance to the natural route of infection. To enable precise delivery of pathogen to the lower respiratory tract in a manner that imposes minimal biosafety risk, nose-only exposure systems have been developed. Early inhalation exposure technology for infecti...

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...

Recent searches for new particles and rare Z” decqs performecl,at LEP are reviewed. Invited talk at the SLAG S ummer Institute Toyrcal Conjerence, August 1931

steelmaking slag of mobarakeh steel company (msc) has a high iron content which makes it unsuitable for conventional slag recovery; as in cement industries. on the other hand, eaf slag in this company is almost free of zinc because of using more than 90 percent dri in the charge. therefore, removal or recovery of iron from the slag can be a suitable solution to slag recovery in this company. in...

Standard asphalt mixtures for road infrastructures consist of natural aggregate and bitumen. A number of research efforts have successfully investigated the possibility of replacing the conventional aggregate skeleton with industrial by-products such as slag originating from steel production process. However, little is known on the effect of steel slag on the mixtures functional performance and...

The presence of high level of heavy metals involves a human healthy risk that could induce chronic diseases. This work reports on the metal contamination due to heaps of steel-slag accumulated during more than 40 years in allotments and industrial areas in the southern part of Madrid (Spain). Several slag and soil samples were collected in an area of 10 km(2) and characterized by different conv...
