Copper Slag Sandblasting Sand, US 60 100 / Ton, Henan, China, TONTEN, from Gongyi Tonten Abrasive Co., Ltd. on
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 .
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 ...
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.
Production and Properties of Copper Slag. ... of CS and kg of sand are higher than those of 1 kg of sand. If CS replaces sand and the leftover sand replaces crushed rock sand, the net embodied ...
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.
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 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.
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.
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.
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.
"Evaluation of Substitute Materials for Silica Sand in Abrasive Blasting," dated June 9, 1995. KTATator, Inc. (KTA) responded to the invitation with a proposal entitled, ... Coal Slag (CS) 7 products Coal Slag with Dust Suppressant (CSDS) 2 products ... Copper Slag (CP) 4 products Copper Slag with Dust Suppressant (CPDS) 1 product
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 ...
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,
Copper Slag (CS) is a byproduct material produced from the process of manufacturing copper. The chemical composition of the of the slag has 30 35% of copper, iron and sulphur each along with around 12% of silica and 5% of calcium with high density.
Synopsis 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 ...
Oct 02, 2019· Copper slag is a byproduct created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of nonmetallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
CONCRETE MIX DESIGN USING COPPER SLAG AS FINE AGGREGATE . ... Copper slag (CS) is an industrial byproduct obtained through the manufacture of copper .
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
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 ...
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.
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 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
