Chromium Stability in Steel Slags
steel research international, 2017Chromium is an essential element in steelmaking industry. Steel slag inevitably contains some chromium and there is a risk of Cr emission from slag to the environment, however, in which form the emission of the element occurs and whether it is a hexavalent Cr is a concern.

Phosphorus removal using steel slag
Acta Metallurgica Sinica (English Letters), 2006Steel slag is a byproduct produced in large amounts in the steel-making process. It is an important resource that can be effectively utilized. An experiment was described in which steel slag was tested as an adsorbent for the removal of phosphorus from waste water. Phosphorus removal depended on the amount of steel slag added, the pH value, the contact

Construction and Building Materials, 2020
Abstract In order to find an effective way to use steel slag (SS), this study explored the possibility of using SS and ground granulated blast-furnace slag (GGBS) as a composite additive in alkali-activated high calcium fly ash (FA) binder. Through a series of experiments, the setting times, flow, viscosity, compressive and flexural strengths ...

Dissolution of steel slags in aqueous media
Environmental Science and Pollution Research, 2017Steel slag is a major industrial waste in steel industries, and its dissolution behavior in water needs to be characterized in the larger context of its potential use as an agent for sequestering CO2. For this purpose, a small closed system batch reactor was used to conduct the dissolution of steel slags in an aqueous medium under various dissolution ...

Pilot-scale steam aging of steel slags
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2017Solid waste management has gained importance in the steel industry in view of rising environmental concerns and scarcity of raw materials. In spite of significant developments in reducing waste generation and development of recycling technologies, steel slag is still a concern for the industry as most of it is dumped.

Properties of steel slag aggregate and steel slag asphalt concrete
2010Ferrous slags (blast furnace slag, steel slag, ferro-alloy, etc.) are the industrial byproducts from a greatest interest to the pavement construction industry, given their wide availability and scope of uses. Above that the production of aggregate from slag instead from rock would decrease the amount of raw material exploitation and enable further ...

Composite foamed alkali-activated concrete with slag and steel slag
Magazine of Concrete Research, 2020Thermally expandable foaming microspheres (FMS) are used as a foaming agent in many different fields due to their excellent dimensional stability and elastic properties. In this study, lightweight thermal insulation materials were prepared by adding FMS to foamed concrete containing alkali-activated steel slag and blast-furnace slag.

Composition Characteristics of Reconstructed Steel Slag with Electric Furnace Slag
Applied Mechanics and Materials, 2014Mineral compositions and granule morphology of reconstructed steel slag with electric furnace slag as an adjusting component were discussed. The vitreous content with hydrofluoric acid erosion and petrographic analysis were carried out. The results showed that the vitreous content of steel slag was lower than that of raw and first decreases and then ...

Mineral CO2Sequestration by Steel Slag Carbonation
Environmental Science & Technology, 2005Mineral CO2 sequestration, i.e., carbonation of alkaline silicate Ca/Mg minerals, analogous to natural weathering processes, is a possible technology for the reduction of carbon dioxide emissions to the atmosphere. In this paper, alkaline Ca-rich industrial residues are presented as a possible feedstock for mineral CO2 sequestration.
