Use of ladle furnace slag containing heavy metals as a binding material in civil engineering

Science of the Total Environment, 2020
The disposal of ladle furnace slag (ladle slag, LS) containing traces of heavy metals produced during steelmaking has become an environmental issue. The use of LS as a binding material in civil engineering is a potential solution.

Generation, utilization, and environmental impact of ladle furnace slag: A minor review

Science of The Total Environment, 2023
More than 20 million tons of ladle furnace slag are produced annually. This slag is mainly treated by stockpiling; however, stacking results in dust and heavy metal pollution. Utilizing this slag as a resource can reduce primary resource consumption and eliminate pollution.

Immobilization of lead (Pb) using ladle furnace slag and carbon dioxide

Chemosphere, 2022
Global sustainable development faces challenges in greenhouse gas emissions, consumption of energy and non-renewable resources, environmental pollution, and waste landfilling. Current technologies for immobilization of heavy metals face similar challenges; for example, the use of cement, magnesia, lime, and other binders for immobilization of heavy ...

Ladle Furnace Slag as a Sustainable Binder for Masonry Mortars

Key Engineering Materials, 2019
Nowadays, the environmental aspect of industrial waste management has got urgent. The reusing of these residues in the civil building is increasing, since all industries have developed a growing concern for the emptying of natural resources. The ladle furnace slag (LDF-slag), a by-product of the secondary refining of steel, is mainly composed of ...

Recycling Ladle Furnace Slag as Flux in Steelmaking: A Review

Journal of Sustainable Metallurgy, 2019
The use of synthetic fluxes in secondary steelmaking not only improves the properties of top slag and steel quality but also increases the production cost. Ladle furnace (LF) slag can be used as a replacement to synthetic fluxes owing to its chemical and mineralogical compositions.

The durability of masonry mortars made with ladle furnace slag

Construction and Building Materials, 2011
Abstract Ladle furnace basic slag is a by-product of the steelmaking industry. This study examines the properties of masonry mortars made with ladle furnace basic slag and the other conventional components such as sand, cement, and admixtures. Eight different mixes were prepared and the main properties of the resulting mortars were analysed: density,

Ladle slag-refining of electric furnace steel

JOM, 1957
Striving to increase steel output per furnace as well as to improve steel quality, one of the leaders of French electric-furnace steelmaking—Ugine— has perfected a ladle slag treatment for rapid desulfurization and deoxidation. The result: tap-to-tap time reduced by more than 50 pct, and output per furnace increased by more than 200 pct.

Cyclic Use of Ladle Furnace Refining Slag for Desulfurization

Journal of Sustainable Metallurgy, 2016
Industrial experiments were carried out to study the cyclic use of ladle furnace refining slag on desulfurization. Sampling of refining slag and steel were undertaken simultaneously at roughly equal intervals of time. The desulfurization capacity remained almost unchanged in the recycling slag compared with the primary slag.
