Slag cement (also called ground granulated blast furnace slag) is a hydraulic cement produced during the reduction of iron ore to iron in a blast furnace. Molten slag is tapped from a blast furnace, rapidly quenched with water ("granulated"), dried and ground to a fine powder. The rapid quenching "freezes" the molten slag in a glassy state ...

Ladle slag is a byproduct formed during the ladle refining stage of steel making. It is a dusty material that has been considered industrial waste. Technical advancements towards a sustainable industry led to the development of different applications for ladle slag. Depending on the processing methods during the steel slag …

Steel slag is a byproduct of steel production, formed when impurities in the raw materials react with oxidants and fluxes in the steelmaking process. It consists of various minerals and can be used as a construction material due to its high hardness, durability, and ability to improve concrete properties.

Our sustainable, dry method for slag granulation derives value from waste and has the potential to transform the metal and cement industries.

The slag utilisation saves natural resources as well as primary energy and it significantly reduces the CO 2 footprint of cement and concrete [2, 3]. Due to the lack of hydraulic properties the crystalline steel slags are mainly used as road-making aggregates substituting natural materials.

This paper reviews the production, processing, and characteristics of steel slag, and its use as a cementing component in different cementing systems.

Waste recycling and reuse is an important component of sustainability. Extensive research is being conducted to address this issue by incorporating industrial by-product such as steel slag, copper slag, fly ash, ferro-chrome slag, and so on into the construction industry. Steel slag, which is mostly calcium carbonate, is created as a by …

The research hypothesis aims to substitute a portion of cement with vitrified slag from solid waste incineration residue to achieve its resource utilization in the concrete production process.

Semantic Scholar extracted view of "Study on hydration process of alkali-activated slag cement activated by weakly alkaline components" by Shuya Yu et al.

The alumina in the slag cement can react with more of the finely divided limestone in Type IL cement to form additional carboaluminate hydrates that then results in reduced porosity and increased early‐age strength of concrete.

Recycling: Following removal of entrained metal, slag can be returned to the blast and steel furnaces as ferrous and flux feed, but data on these returns are incomplete. Entrained metal, particularly in steel slag, is routinely recovered during slag processing for return to the furnaces and is an important revenue source for slag processors; data on metal …

Sustainability. Slag cement is a recovered material from the iron production process and because of this, reduces the environmental impact of concrete mixtures. Additionally, slag cement is very effective in reducing permeability and increasing durability in concrete.

Recycling steel slag into asphalt concrete is an important way to save natural resources and protect the environment. The high asphalt absorption and adsorption and the sensitivity of steel slag aggregate (SSA) to the combined damage of temperature and moisture (volume expansion and poor durability under freeze-thaw cycle damage) still …

Slag has cementitious properties similar to portland cement. It is typically used with portland cement at dosages between 25–80 percent, depending on the engineering parameters. The primary raw material of slag cement is a byproduct from the iron blast furnace process. It is a recycled, environmentally friendly product.

Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is ...

The possibility of using granulated slags resulting from the smelting of lead and zinc in partial, or total replacement of sand in mortars and concret…

Ni slag is generated during the pyrometallurgical processing of Ni at 1500–1600°C ( Maragkos et al., 2009 ). Producing 1 ton of Ni in a flash smelting furnace or electric arc furnace will generate around 6–16 tons of slag. The ores mainly used for Ni production are high-magnesium Ni oxides ores, which result in a large amount of Mg in the Ni slag ( …

The Manufacturing Process. Manufacturing Skyway Slag Cement requires two basic processes: granulation and grinding. Blast-furnace slag is produced in a blast furnace during the reduction of iron ore to iron. It consists of non-metallic minerals, which are tapped slag from the blast furnace while molten. By processing blast furnace slag into ...

Sustainability. Slag cement is a recovered material from the iron production process and because of this, reduces the environmental impact of concrete mixtures. Additionally, slag cement is very effective in reducing permeability and increasing durability in concrete.

Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties. In this article we discuss about …

The slag processor may also be required to satisfy moisture content criteria (e.g., limit the amount of moisture in the steel slag aggregate prior to shipment to a hot mix asphalt plant) and to adopt material handling (processing and stockpiling) practices similar to those used in the conventional aggregates industry to avoid potential segregation.
