In this study, the use of steel slag as fine and/or coarse aggregate in concrete is investigated. For this purpose, 12 different concrete mixtures with different water/cement ratios of, and which include steel slag aggregate as fine and/or coarse aggregate are prepared.

Steel industry results in accumulation of steel slag wastes causing severe environmental problems. These wastes can be recycled and replace natural aggregates resulting in sustainable green concrete. In this research, natural aggregates in selfcompacting concrete (SCC) are replaced, wholly or partly, by steel slag coarse aggregates that were produced by crushing byproduct boulders obtained ...

coarse aggregate, such as the spaces between steel reinforcing bars, without segregation. Resistance to segregation The ability of SCC to remain homogeneous during transport, placing, and after placement. 9. Constituents of SCC ; With regard to its composition, SCC consists of the same components as conventionally vibrated concrete, which are ; Cement

use of copper slag as a replacement for fine aggregate is investigated. Three slender reinforced concrete columns of 150x150x2500mm were tested for monotonic axial compression load until failure. The concrete mix included ordinary Portland cement, fine aggregate, 10mm coarse aggregate and copper slag. The ratios of copper slag to fine aggregate were 0%, 40% and 80%.

biodegradable components of Ewaste (EW) as a partial replacement of the coarse experimental study is made by preparing specimens by utilizing Eplastic waste particles as coarse aggregates in SelfCompacting Concrete (SCC) with a percentage replacement from 0% to 30% (5%, 10%, 15%....up to 30%). And Conventional specimens

Steel slag recycling Harsco M. The steelmaker benefits from slag recycling by avoiding the cost of landfill. The community benefits, too. Slag is a manmade mineral, therefore its use as an aggregate in place of a natural aggregate product avoids the environmental footprint from quarrying.

parameters included the amount of coarse aggregates (less content in SCC mixes), the MNS of coarse aggregates and the shear spantodepth ratio. It was found that an increase in the size of coarse aggregate from 12 to 19 mm in SCC mixes decreased the shear capacity of concrete (Vc) and

Oct 16, 2019· The next step of the work plan, SS was employed as a partial replacement for (sand) fine aggregate and also RCA was applied as a partial replacement for (gravel) coarse aggregate. The proportions of SS and RCA were calculated based on the criterion of particle size after performing sieve analysis according to the American Concrete Institute standards.

partial replacement of coarse aggregate with steel slag and fine aggregate by msand in concrete August 11, 2018 ABSTRACT: In this paper, researchers studied and developed waste management strategies to apply for advantages for specific needs.

Having specific gravity of and fineness modulus of has been used as fine aggregate for this study. C. Coarse Aggregate. Coarse aggregate obtained from local quarry units has been used for this study, conforming to IS: is used. Maximum size of .

Since the new trends in concrete construction goes towards selfcompacting green concrete, it becomes important to study the possibility and effectiveness of using steel slag aggregate (SSA) in selfcompacting concrete (SCC) as a replacement of coarse aggregate.

aggregate, coarse aggregate and water. Concrete is normally used in the frame structure. But there is some limitation like selfcompaction, surface finishes, maintains strength at congested area. Due to this limitation we are trying to make self compacting concrete with the use of mineral admixture.

Dec 15, 2016· Read "Effect of iron slag as partial replacement of fine aggregates on the durability characteristics of selfcompacting concrete, Construction and Building Materials" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at .

replacement of fine aggregate by steel slag whereas at 30% replacement of sand by steel slag there is reduction in strength.

ceramic. Therefore the aim of this research is to use the ceramic waste tiles in SCC as a partial replacement of coarse aggregate, and investigate the effect of hightemperature (room temperature to 400˚C) on the strengths of this type of concrete. The experimental program consists of casting and testing of 180 specimens (cubes 100 x100x100
