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 state-of-the ...
The specific gravity of sand and copper slag was 2.67 & 2.75 respectively as shown in Table 2.1. The water absorption of 20 mm coarse aggregates, sand &copper slag was found to be 0.609, 1.01 and 0.65 respectively. It was found that water absorption of copper slag was very low as compared with the natural sand and workability of concrete is
Durability characteristics of copper slag concrete with fly ash The properties of fine aggregate, CS and coarse aggregate are given in Table 2 [15]. Specific gravity and density of CS amount to 3.52 and 1750 kg/m 3, respectively. These qualities show that the density of CS is .
Copper slag is a by-product of copper extraction by smelting.During 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.
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
Copper slag blasting edia/grit - is manufactured of the granulated slag of copper refineries, and used for blast-cleaning 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.
Production and Properties of Copper Slag. ... of CS and 0.9 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 Sandblasting Sand, US $ 60 - 100 / Ton, Henan, China, TONTEN, CS.Source from Gongyi Tonten Abrasive Co., Ltd. on Alibaba.
130 mm; for CS-C 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 .
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,
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. 3.1. Copper Slag (CS) Availability in Singapore
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 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.
Oct 02, 2019· Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic 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.
S Sand,CS Copper Slag, Figure-1 different percentage of CS. Figure-2 different percentage of CS. The results show that the compressive strength of CS(copper slag) concrete is increased when compared to control concrete (35.66MPa to 48.76MPa cured at 28 days), where as the increase in strength is more or less the same different percentage of CS ...
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 ...
CONCRETE MIX DESIGN USING COPPER SLAG AS FINE AGGREGATE . ... Copper slag (CS) is an industrial by-product obtained through the manufacture of copper .
INFLUENCE OF COPPER SLAG AS PARTIAL REPLACEMENT OF SAND IN CEMENT CONCRETE Suresh T, Ravikumar C PG Scholar, Easa College of Engineering and Technology, Coimbatore Assistant Professor, Easa College of Engineering and Technology, Coimbatore Abstract-The development of construction materials
Copper Slag (CS) is a by-product 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.
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 ...
