The leaching of CS as sand in concrete was not influenced by the water/cement ratio of the concrete ... This chapter discusses the leaching of toxic elements of copper slag (CS), the associated environmental impact and case studies in which CS is used in various construction applications.
S Sand,CS Copper Slag, Figure1 different percentage of CS. Figure2 different percentage of CS. The results show that the compressive strength of CS(copper slag) concrete is increased when compared to control concrete ( to cured at 28 days), where as the increase in strength is more or less the same different percentage of CS ...

Copper slag blasting edia/grit is manufactured of the granulated slag of copper refineries, and used for blastcleaning of metal surface. Copper slag has also gained popularity in the building industry for use as a fill material. Contractors may also use copper slag in place of sand during concrete construction.
To ensure its future economic viability while growing in a sustainable manner, it is essential that Singapore''s construction projects have access to alternative materials that are viable substitutes for natural sand and gravel. Copper Slag (CS) Availability in Singapore
Copper slag has a specific gravity of which is higher than that for sand () and OPC () which may results in production of HPC with higher density when used as sand substitution. Also, the measured water absorption for copper slag was % compared with % for sand.
Addition of up to 50% of copper slag as sand replacement yielded comparable High performance concrete Copper slag strength with that of the control mix. However, further additions of copper slag caused reduction in the Waste material strength due to an increase of the free water content in the mix.
The effect of copper slag (CS) on the engineering properties of road pavements is described based on the literature published since 1992. CS has a similar California bearing ratio to natural sand. When used in hydraulically bound applications, it increases workability and compressive and flexural strengths, and decreases drying shrinkage of ...
copper slag increase in slump value and decrease the compressive strength[4] KHALIF substitution of up to 40–50 % copper slag as a sand replacement yielded comparable strength to that of the control mixture. However, addition of more copper slag
CONCRETE MIX DESIGN USING COPPER SLAG AS FINE AGGREGATE . ... Copper slag (CS) is an industrial byproduct obtained through the manufacture of copper .
The Consequences of Substituting Sand with Used Copper Slag in Construction An Embodied Energy and Global Warming Potential Analysis using Life Cycle Approach and Different Allocation Methods Harn Wei Kua Summary Using waste copper slag (CS) as a replacement for sand in concrete mixture is becoming popular in Singapore and around the world.
Table 3. Test results of trial mixes made using 50% CS as replacement of natural sand 3 Magazine of Concrete Research Use of copper slag and washed copper slag as sand in concrete: a stateofthe ...
Copper slag is a byproduct of copper extraction by smelting, impurities become slag which floats on the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below.
Aug 12, 2019· Utilization of high volume Copper Slag (CS) in concrete is the aim of present work. ... The maximum flexural strength of MPa is obtained when sand is replaced with 40% copper slag when sand is replaced with copper slag beyond 40% the strength of concrete was reduced and least flexural strength of MPa is obtained when sand is replaced ...
Ebonygrit is a disposable highdensity blasting slag made from a byproduct of copper production. Ebonygrit distinguishes from lightweight blasting slag, due to its high density property. Typically, the majority of its composition is iron oxide and silicon dioxide, formed when molten slag .
A research was performed to generate specific experimental data on the potential use of copper slag (CS) and ferrous slag (FS) as sand replacement in concrete. The cement used in this study was 53 ...
Building Construction Authority of Singapore restrains the substitution of copper slag instead of sand up to 10 % by weight in development designing with extra prudent measures [5]. FIG. 1 COPPER SLAG Copper Slag (CS) is at present being utilized for numerous purposes from area filling to coarseness impacting. At present,
Aug 20, 2014· Abstract. This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering.
Consolidating 125 studies undertaken since 1989, the effects of copper slag (CS) used as sand on concrete properties are discussed. CS increases the consistence of concrete but, if uncontrolled, this may affect its stability. The setting times and early strength development are retarded. It has been commonly reported that concrete containing up ...
Rapijet CS Copper Slag. RS Blastech''s copper slag is manufactured from processed mineral slags which have less than % free silica, developed within the Control of .
fine aggregate in reinforced concrete slender columns A. S. Alnuaimi ... substitution of natural sand by copper slag. Workability was also reduced, ... earlier failure load than when the percentage of copper slag was low. The failure of the 0% CS column was more sudden with less time between the start of
130 mm; for CSC types, containing copper slag and 0% sand, the measured flow is 220 mm. This considerable increase in the workability with the increased copper slag quantity is attributed to the low water absorption and glassy surface of copper slag [17] compared to sand; these cause a .
The specific gravity of sand and copper slag was respectively as shown in Table The water absorption of 20 mm coarse aggregates, sand copper slag was found to be, and respectively. It was found that water absorption of copper slag was very low as compared with the natural sand and workability of concrete is
