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 self-compacting steel slag epoxy resin concrete (SERC) was designed with steel slag as aggregate and epoxy resin as binder for rapid repair of road expansion joints and pavement.
In this study, the silica fume replacement rate, fly ash replacement rate, and curing temperature were regarded as the independent variables, and the compressive and flexural strengths were regarded as the response values. The response surface method was used to construct the response surface polynomial regression model and obtain the …
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 …
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 …
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 compressive, split tensile and flexural properties of concrete containing steel slag are compared with that of concrete containing river sand and also manufactured sand. But in this paper only the effect of using granulated steel slag in concrete mixes as an fine agate on compressive strength and workability is discussed.
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).
2.1 Materials. AOD steel slag was procured from the Jindal Stainless Steel Limited, Hisar city, India. Chemical constituents of cement and AOD steel slag are shown in Table 1.Figure 1 shows the SEM and EDS images of the AOD steel slag. The SEM image of AOD steel slag showed a flaky shape of particles that are somewhat similar to …
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 ...
For this study M40 grade of concrete with replacement of high volume steel slag is utilized. Quality is determined from experimental test values. ..., Issue 2, June 2015, pp. 51-57 Beneficial Effects of Steel Slag on Concrete Girish Sharma1, Ritu goyal2, Abhishek Gupta3, Devinder Sharma4 1,3M.Tech Student, Deptt. of Civil Engg., IGCE ...
This paper reviews the production, processing, and characteristics of steel slag, and its use as a cementing component in different cementing systems. The …
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 ...
The wet-grinding specimens presented a higher hydration heat than that of raw steel slag specimens, and the microstructure of 3 μm-40% (3 μm steel slag mixed with cement as a dosage of 40%) is ...
The analysis results indicate that the incorporation of steel slag powder (SSP 3) may have adverse effects on the initial setting time, volume stability, …
Qiang et al. stated that when cement is replaced with steel slag, at constant water binder ratio (W/B), it was seen that as the steel slag quantity is increased, the early strength goes on decreasing and at 30% of steel slag utilization; the compressive strength is much lower in comparison with normal concrete.
The present investigation is conducted to evaluate the effect of steel slag coarse aggregates on mechanical properties and fatigue behaviour of Alkali-Activated Slag Fly Ash Concrete (AASFC) mixes. AASFC mixes were prepared with steel slag coarse aggregates by replacing natural coarse aggregates at various replacement levels (0, 25, …
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. The main issue regarding the …
The analysis of system effects of changed quality of lime raw material, i.e. limestone and ... argue the benefits of replacing cement clinker with slags. An increased utilisation of slags ... strong negative effect on the P refining capacity of the slag and, hence, on the liquid steel quality, as the P partition ratio (P)/[P] decreases with ...
Sustainability Potential Evaluation of Concrete with Steel Slag Aggregates by the LCA Method. by. Vojtěch Václavík. 1,*, Marcela Ondová. 2,*, Tomáš Dvorský. 1, Adriana Eštoková. 2, Martina …
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 on the characteristics of concrete, and its …
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 ...
The characteristics of the ultrafine steel slag powder and the influence of ultrafine steel slag powder with different contents on the properties of concrete were analyzed, the results ...
Alkali-activated cement (AAC) is either clinker-less or free, and it is also environmentally friendly due to its low carbon footprint and wide range sources. Industrial wastes, like steel slag and blastfurnace slag, usually have latent hydraulic reactivity, and can be used as precursors of AAC. Both clinkerless and clinker-free AAC were prepared …
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.
During the modeling procedure, the most significant factors affecting the compressive strength of concrete with steel slag replacement were considered, including the curing time of 1–180 days ...
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.
