Steel slag can be used to replace cement and natural aggregates in concrete. Nonetheless, utilizing untreated steel slag directly presents a substantial hazard to the structural characteristics and durability of concrete.
In addition to their use in the standard concrete, few studies on the reuse of the EAF slag as a partial substitution of the natural aggregates in special concretes are available in the literature: pervious concrete, high-strength concrete, self-compacting concrete, and fiber reinforced concrete (using both steel and synthetic fibers) .

Moreover, the study contributes to the circular economy ...
Piles of steel slag, a solid waste generated from the iron and steel industry, could be seen due to no utility found for the past century. Steel slag has now gained much attention because of its new applications. The properties of slag greatly influence its use and thus had got varied applications. The chemical composition of steel slag varies as …
The needs for alternative sources of aggregates are pressing. Steel slag, which is a by-product of steel manufacturing, could be an alternative solution. This paper presents the results from experimental works completed at Qatar University to check the applicability of using steel slag aggregates in concrete mixes in Qatar.
Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete. It can also be used to absorb contaminants like phosphate, magnesium, iron, calcium, silica and aluminium in the wastewater treatment process, but loses its effectiveness over time.
Utilization of the waste steel slag in concrete can produce green concrete by contributing to energy savings and reducing the greenhouse emissions associated …
Three methods have been widely employed to improve the reactivity of steel slag and concurrently reduce its potential harm on cement-based host materials: (i) …

Steel slag is a solid waste produced in crude steel smelting, and a typical management option is stockpiling in slag disposal yards. Over the years, the massive production of steel slags and the continuous use of residue yards have led to vast occupation of land resources and caused severe environmental concerns. Steel slag …
Steel slags are industrial by-products of steel manufacturing, characterized as highly calcareous, siliceous and ferrous. They can be categorized into basic oxygen furnace (BOF) slag, electric arc furnace (EAF) slag, and ladle furnace (LF) slag. They are found to be useful in many fields, such as road construction, asphalt concrete, …
Steel slag has great potential for its reuse in concrete production. Despite its volume changes over time, steel slag can be applied in concrete as a cement replacement (normally) or as a substitute for natural aggregates (rarely). This paper focused on an investigation of concrete with steel slag as a substitute of natural gravel aggregate.
A steel-making slag (basic oxygen furnace) obtained from the Kardemir Steelworks was modified to be used as a clinker additive in the cement industry. This study confirmed that the compressive streng...
The first commercially available slag-based cement was developed in Germany in 1865 [17]. Currently, over 200 million tons of slag cement is used worldwide annually [18]. Metal slag is a ferrous slag, industrial waste, and by-product of the iron industry produced during iron processing in steel plants due to removing impurities from …
