Waste glass (WG) and steel slag (SS) are industrial by-products with properties that benefit sustainable concrete production. This research aims to produce concrete with the highest compressive strength and lowest thermal conductivity for green buildings by using WG and SS as the cement and coarse aggregates, respectively. Such a combination is remarkable; …
In concrete steel slag has been incorporated as cementing material/aggregate, which increases the strength of concrete with the utmost result obtained is 67% of steel slag replacement for recycled aggregate (Qasrawi, 2014). BOF slag was used as a hydraulic binder in which the slag was rapidly quenched and studied for its mechanical properties.
This paper aims to study experimentally, the effect of partial replacement of fine aggregate by steel slag (ss), on the various strength and durability properties of concrete by using the mix designs .the optimum percentage of replacement of fine aggregate by steel slag is found. Workability of concrete gradually decreases, as the
Coarse Aggregates Anand Ram Sinha Department of Civil Engineering, Sagar Institute of Research and Technology, Bhopal, India.anand.prof008@gmail Abstract—Most of the volume of concrete is aggregates. Replacing all or some portion of natural aggregates with steel slag would lead to considerable environmental benefits.
Investigates mild steel slag which has highest content in concrete mixture, was used as replacement for aggregate or stone. Benefits can therefore be accomplished through the use of mild steel slag rather than natural aggregates. Compressive power and the other experiments showed that mild steel slag exceeded natural aggregates.
steel slag as an aggregate in concrete []. They concluded 1 that air-cooled steel slag, which has a low amorphous silica content and a high ferric oxide content, may not be suit-able for blended cement production. However, they found that utilizing steel slag as an aggregate in concrete mixes oered advantages over conventional aggregate mixes ...
Building on our previous research (Singh and Anand 2024), which identified 50% steel slag replacement as optimal for SCC performance, this study explores the addition of hybrid fibers (50% steel and 50% polypropylene) at varying proportions (0.25–2%). The main objective of this paper is to optimize SCC using 50% steel slag as a fine aggregate replacement and …
Hasita et al. compared the mechanical performance of the mixture with different aggregate sizes from limestone, granite, and steel slag. The results showed that the marshall stability of slag asphalt was 46.5% and 50% higher than limestone and granite asphalt, respectively, which was due to the lower LA (Los Angeles Abrasion) and ACV (Aggregate …
In this study, the impact of replacing fine aggregates with steel slag on concrete mixtures was evaluated, yielding the following conclusions: Workability decreased as the proportion of iron slag increased, resulting in slump values as low as 50 mm at 50% replacement. This reduction is due to the rough and angular surface texture of iron slag ...
Fortunately, steel slag can replace natural aggregates at ratios up to again with high compressive strength values thanks to its high compressive strength. These are significant results for the usage of an industrial by-product as a sustainable construction material in the production of sustainable concrete. In contrast, its angular shape ...
Replacing all or some portion of natural aggregates with steel slag would lead to considerable environmental benefits. Steel slag is currently used as aggregate in hot mix asphalt surface ... Fine aggregate to slag replacement proportions: shown in Table 3 (all weights in kg/cum) Grade M20 M30 % FA GGBS FA GGBS 0% 964.3 0 867.1 0 ...
Preparation of specimens and mix proportions. The study utilized ordinary Portland cement in specific mixing proportions, as shown in Table 3, to assess the mechanical strength, durability, and microstructural properties of cement mortar.A total of 13 mixes of cement mortar are prepared using steel slag and PVC powder as a partial replacement for cement according …
1. Introduction. Steel slag is a by-product of steel manufacturing [].Approximately 160 kg of steel slag is generated per ton of steel produced [].The common chemical compounds in steel slag are SiO 2, CaO, Fe 2 O 3, Al 2 O 3, and MnO [3, 4].The major mineral components of steel slag are C 3 S, C 2 S, C 4 AF, RO phase, and free-CaO [5, 6].Many studies have shown …
Typical morphology of steel slag [].(a) BOF steel slag.(b) EAF steel slag.(c) LF steel slag.BOF steel slag is the solid waste produced in the converter steelmaking process, and its discharge is approximately 100–150 kg per ton of BOF steel [20,21,22,23].BOF steel slag commonly has a grayish-white appearance and a vesicular nature, with many non-interconnected pores [].
To solve the problem in effective manner steel slag and walnut shell is used in concrete by replacing natural aggregates. In this study, the replacement was done with fine aggregate by steel slag for different proportions of 0%, 10%, 20%, 30%, 40%&50% and coarse aggregate by walnut shell at constant proportion of 20%.
As the replacement rate further increases to 90 %, the distribution of the steel slag aggregates in the concrete becomes more stable and uniform. As shown in Fig. 18, when the replacement rate of steel slag aggregate is 50 %, the porosity of the concrete section is lower, and the aggregates and slurry are more densely filled. Some aggregate ...
This review paper focuses on the role of steel slag aggregate (SSA) and recycled coarse aggregate (RCA) in concrete, considering different percentages of SSA (ranging from 0 to 50%) and RCA (from 0 to ). ... This indicates that concrete should only replace steel slag at a level of around 30%, since doing so might weaken the material's ...
Hot mix asphalt (HMA) is a merger of 95% stone, sand, or gravel bound together by asphalt cement. Steel slag is a byproduct of the steel making process. The use of Steel slag in HMA can have a large economical, environmental, and engineering impact in pavement construction. Introduction of steel slag as aggregates reduces
