Copper Slag. CS has also been ground to determine its suitability for use as a component of cement (regardless of the type of cooling process applied), though information available in this area has often tended to be somewhat problematic (Lorenzo et al., 1991; From: Sustainable Construction Materials: Copper Slag, 2017. Related terms: Smelting ...[email protected]
Aug 01, 2009 Copper slag has a specific gravity of 3.4 which is higher than that for sand (2.77) and OPC (3.15) which may results in production of HPC with higher density when used as sand substitution. Also, the measured water absorption for copper slag was 0.17% compared with 1.36% for sand.
Oct 14, 2021 Copper slag is an abrasive blasting grit (by-product) made of granulated slag from metal smelting process and refining of copper in which sulphur …
May 03, 2014 Physical properties. Copper slag grains have a color of black glassy type and a fineness modulus of 3.5. The hardness is about 7 Moh’s scale. Other typical physical properties are given in Table 2.In order to use copper slag as a mineral admixture, it was necessary to carry out an experimental study associating grinding time, average diameter, and pozzolanic activity assessed in mortars .
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.
Copper slag is an abrasive blasting grit made of granulated slag from metal smelting process ( also call iron silicate). Copper Slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-21/2 and SA-2.
May 01, 2007 Table 9: Performance of slag cements prepared by using 35% copper slag at different fineness. Observation and Analysis: Chemical analysis of granulated blast furnace and copper slag are given in Table 1. The results indicate that granulated blast furnace slag conforms to all the requirements of Indian Standard Specification IS: 12089-1987 for the manufacture of PSC unlike copper slag.

Copper slag (CS) is a waste product which comes out from the smelting process. admixture can be used as an alternative material to that of sand in road construction. If the copper slag is It has been estimated that for every tonne of copper produced, about 1.8-2.2 tonnes of copper slag …
This Industrial Copper Slag Blasting Service is used in the industrial belts to clean or smoothen any uneven surface like large-scale metals. The blasting is mainly used to remove thick, tough heavy dust, rust and paints from heavy machines and tanks. An ebony grit is formed from a by-product of the manufacturing of copper that is processed into an abrasive by Opta mineral.
In which are the Industries copper slag is used? It is used widely in shipyard, steel fabrication, oil and gas and construction chemicals. What are the physical properties of copper slag? Hardness - 6-7 Mohs, Chlorides - 25 ppm, Conductivity - 25 mS/m pH - 7, Bulk Density at 250C - 1.75 Tonnes/m3 , and Specific Gravity at 250C -3.5 kg/m3.
Copper slag produced during the matte smelting and refining of copper ore, during which, the iron present in the copper concentrate combines chemically at 1200 C with silica present in flux materials such as river sand/silica sand/ quartz fines to form iron silicate, which is termed as copper slag.
Contractors may also use copper slag in place of sand during concrete construction. Copper slag can also be used as a building material, formed into blocks. Copper slag is widely used in the sand blasting industry and it has been used in the manufacture of abrasive tools.
Properties And Effects Of Copper Slag In Concrete 47 2.7 Fineness Modulus The fineness modulus of coarse aggregates (20 mm & 10 mm), sand and copper slag are 7.10, 6.77, 2.94 and 4.06 respectively. Table 3.2 to 3.3 shows the fineness modulus of 20 mm, 10 mm coarse aggregates, sand and copper slag respectively.
