In the present work, a series of bamboo-fiber-reinforced epoxy composites are fabricated by using red mud and copper slag particles as filler materials. increasing copper loses in the discard slag. %%EOF They do not shatter when they are dropped or become brittle when cooled below 0°C. The average composition of primary copper slag corresponds to 30–40 % iron, 35-40% silica, less than 10 % of alumina and calcium oxide and copper content is around 1 %Cu, similar to the ore mined. characteristics of copper slag incorporated concrete was found out by replacement of 20%, 40%, 60%, 80% and 100 %, out of this 40% replacement gives highest compression strength at 28 days, more than 37.55 % higher in compression strength and 5.3% higher in Split Tensile Strength and 40.72% in flexural strength compare to conventional mix. The geotechnical properties include sieve analysis, specific gravity, maximum and minimum dry unit weights, angle of shearing resistance, one-dimensional compressibility, and permeability. Copper is non-magnetic and non-sparking. Use of copper slag in concrete industry as replacement of cement or/and fine aggregates can have the benefit of reducing the costs of disposal and minimising environmental pollution [1,2]. A filler plays an important role in determining the properties and behavior of particulate composites. Copper slag has a specific gravity of 4.12 and bulk density of 2.31 g/cc which is higher than that for normal river sand (2.6, 1.53 g/cc) which may result in production of concrete with higher density. As its disposal becomes a concern for environmental protection agencies and governments, possible alternative outlets for this waste material are needed. Copper is reddish colored and takes a bright metallic luster. Because of this, it is used in special tools and military applications. 4) Properties of Copper Slag S.

The slag properties, particularly slag viscosity and electric conductivity, play very important roles in copper concentrate smelting in the Teniente Converter and in slag cleaning in the electric furnace. Blends of copper slag with Portland cement generally possess properties equivalent to Portland cement containing fly ash, but very different to the silica fume incorporation. Also, copper slag exhibits pozzolanic properties since it contains a low content of CaO, and it can possesses cementitious properties as CaO content increases or under activation of NaOH. An experiment was conducted to investigate the strength and durability properties of concrete having copper slag as a partial replacement of sand (fine aggregate) and results have been presented in this paper. Introduction Copper slag (CS) is a waste material widely obtained from the industrial sector in the manufacturing of copper during the matte smelting process. Properties of Fine And Coarse Aggregate. Copper slag is a voluminous waste material obtained during the manufacturing of copper (matte smelting process). Copper slag is used as a building material, formed into blocks. One of the greatest potential applications for reusing copper slag is in concrete production. edge of the slag properties. Two different types of Concrete Grade In Sweden (Skellefteå region) fumed and settled granulated copper slag from the Boliden copper smelter is used as road-construction material. Copper slag and fly ash reduce the heat of hydration more effectively than silica fume in mortars. Non-magnetic. The effects of these two fillers on the mechanical properties of bamboo-epoxy composites are investigated. Thus, high magnetite production in the Peirce Smith converters is not desirable. Copper slag is a by-product obtained during matte smelting and refining of copper. Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. chemical properties such as specific gravity of copper slag is 2.73, firmness modulus is about 8.01, crushing value is 26.37 %, impact value is 30.75% and water absorption is 30.75%. Copper slag recommended less than 40% gives high mechanical properties. 200 sieve) in size. endstream endobj 29 0 obj <> endobj 30 0 obj <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI]/XObject<>>>/Rotate 0/Type/Page>> endobj 31 0 obj <>stream The property of toughness is vital for copper and copper alloys in the modern world.

Effect of Copper Slag As A Fine Aggregate on Properties . � Copper slag is one of the materials that is considered as a waste which could have a promising future in construction Industry as partial or full substitute of aggregates. Slag properties are important since they: (i) have a decisive effect on both process control and on the quality of the product and E. S – 2 (ii) good quality property data are needed to develop reliable mathematical models of the process and to optimise the efficiency of the process and quality control. Beyond which more voids and capillary channels appear in the microstructure of the concrete [9] , [10] . Aggregate acts as reinforcement Table 2. Uses: Copper is widely used in the electrical industry. Also, the measured water absorption for copper slag was 0.40 % compared with 0.83 % for sand. Caijun Shi et al (2008) [9] reviewed the effect of copper slag on the Engineering properties of cement mortars and concrete.
