The goal of the current study is to determine the dissolving effect of slag in water. Five percentage values of slag were taken up for the study: 0%, 2.5%, 5%, 10%, and 20%. The study is based on two methods of mixing. The first method is the traditional mixing process, which involves addition of slag directly with other concrete proportions …
A statistical analysis by EUROSLAG 67 shows that only 6 % of steel slag is used for global cement production. Utilizing steel slag as a replacement in cement production or as a replacement for cement used in the concrete industry could significantly reduce CO 2 emissions 68-72. Fig.
It indicated that when using steel slag, there was a slight reduction in compressive strength and higher values of water absorption. 3.2.4 Granulated Blast Furnace Slag (GGBS) Geopolymer concrete (GPC) and alkali-activated slag (AAS) cement can be produced by using granulated blast furnace slag (GGBS) in concrete.
The shape, size and texture of steel slag will influence the strength and durable properties of slag concrete [16]. The behavior of fresh concrete will decrease with rise in steel slag in concrete mixes. The modulus of the concrete will improve increased steel slag content up to the optimum replacement.
Blast Oxygen Furnace (BOF) slag represents one of the largest waste fractions from steelmaking. Therefore, slag valorisation technologies are of high importance regarding the use of slag as a secondary resource, both in the steel sector and in other sectors, such as the construction or cement industries.
With the increasing demand for specialty and high-quality steel, ladle furnace refining technology has been widely used, which produces a large amount of ladle furnace slag (LFS).
Ground granulated blast-furnace slag (GGBS) is a green construction material used to produce durable concrete. The secondary pozzolanic reactions can result in reduced pore connectivity; therefore, replacing partial amount of Portland cement (PC) with GGBS can significantly reduce the risk of sulfate attack, alkali–silica reactions and …
In this review, steel slag usage in the cement and concrete industry and its environmental effects were examined. Also, its physical and chemical structure, its effect …
Additionally, steel slag is generally considered as a potential substitute for aggregates in concrete or mortar. An increase in the strength of steel slag concrete has been revealed in several ...
Using steel slag to replace natural coarse and/or fine aggregates to make concrete provides a multi-win solution in mitigating the environmental problems regarding huge depletion of natural ...
Slag cement, a byproduct of steel-making, enhances the traditional concrete benefits of strength and durability while offering reductions in waste, energy use and greenhouse gas emissions. ... Lehigh Hanson is proud to be awarded for quality work that sets a precedent of excellence. 2020 SCA Awarded Projects: Akron Hazel Storage Basin (CSO Rack ...
Steel slag is a by-product of the steel industry and can be used potentially as aggregate in the asphalt mixture. This study evaluates the use of Steel Slag Aggregates (SSA) as a substitute for ...
Steel slag particles can potentially be used as aggregates in concrete production. However, the volume stability of steel slag is poor, and the direct use of untreated steel slag...
In this paper, steel slag powder was used to replace part of the cement in road concrete, and group tests were carried out on coarse aggregates with different …
The chemical composition and mineralogical analysis of steel slag are shown in Table 2 and Fig. 1(a) respectively. Density is 2.82 kg/m 3. ... As for 3 μm steel slag – cement specimens, the initial setting time and final setting time prolong with the increasing dosage of steel slag. 3 μm-20% shows a longer initial setting time and a …
Looking at the merits and associated benefits, some of the top steel-producing countries have adopted or upgraded with a recycling technique of steel slags from time to time for various applications (as shown in Fig. 3), such as for road construction, soil enrichment, cement production, etc. Notably, recycling steel slag for a particular …

X-ray diffraction analysis of steel slag samples shows a complex structure with many overlapping peaks reflecting the crystalline phases present in steel slag. These crystalline phases appear to be mainly due to the chemical composition of steel slag and the slow cooling rate applied during processing [ 1, 26 – 28 ].
Abstract. This study aims to investigate the effect of waste steel slag (SS) as partially replaced with cement and fine aggregate on conventional concrete for different mixes named M25, M35, and M47 in terms of compressive strength (CS), electrical resistivity (ER), and piezoresistivity behavior. SS is a molten mixture of silicates and …
Blast Oxygen Furnace (BOF) slag represents one of the largest waste fractions from steelmaking. Therefore, slag valorisation technologies are of high importance regarding the use of slag as a secondary resource, both in the steel sector and in other sectors, such as the construction or cement industries.
