The effects of these two fillers on the mechanical properties of bamboo-epoxy composites are investigated. Copper slag is a voluminous waste material obtained during the manufacturing of copper (matte smelting process). It is malleable, ductile, and a good conductor of electricity and heat. 43 0 obj <>stream %PDF-1.6 %���� 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. copper slag that is produced during matte smelting and converting steps (Al-Jabri [1]). As its disposal becomes a concern for environmental protection agencies and governments, possible alternative outlets for this waste material are needed. They do not shatter when they are dropped or become brittle when cooled below 0°C. However, the … 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. 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 Academia.edu no longer supports Internet Explorer. ABSTRACT Effective extraction of copper from sulphide ores requires careful operation of a copper smelter, which in turn depends very much on the chemistry of the feed and the resulting slag and matte. 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. which is almost similar to the bulk density. Copper slag and fly ash reduce the heat of hydration more effectively than silica fume in mortars. h�bbd`b`*fb`�gb`��eLlf@� ����_@����(~����a5��� �o 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]. Also, the measured water absorption for copper slag was 0.40 % compared with 0.83 % for sand.

When copper liquid settles down in the smelter due to its higher density, the smears of copper slag remaining on the surface (also in liquid … Therefore, the objective of this work is to understand the mechanism of magnetite formation during the blowing to slag and its dispersion in the slag in order to obtain the magnetite content in the range of 18% to 20% in the converter slag. Sorry, preview is currently unavailable. It is second only to silver as an electrical conductor. Uses: Copper is widely used in the electrical industry. The air-cooled and granulated copper slag has a number of favorable mechanical properties for aggregate use, including excellent soundness characteristics, good abrasion resistance, and good stability. The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. Copper slag is used as a building material, formed into blocks. 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. Copper is non-magnetic and non-sparking. A filler plays an important role in determining the properties and behavior of particulate composites.
