The paper presents results of an investigation conducted to study the feasibility of use of Copper Slag (CS) as aluminosilicate material for developing Alkali-activated Cementitious Material (ACM). The effect of addition of mineral admixtures such as Fly Ash (FA) and Metakaolin (MK) on the performance of alkali-activated CS was also …
Copper slag and steel slag are used as conductive fine aggregates in the development of ECM and tire waste, a coarser petroleum by-product is also used as fine aggregate substitute.
Iron blast furnace slag results from the fusion of iron ore, fluxing materials, and coke; the reduction reactions; and the separation of iron from the ore. As indicated in Chapter 2, the term blast furnace slag is used often to refer to iron blast furnace slag to distinguish it from other types of blast furnace slag such as copper, lead, and zinc blast furnace …

The work was investigated for split tensile test, compressive strength as well as durability of concrete. The test result shown that compressive strength and durability were nearer to the conventional concrete at 40% replacement with Copper Slag. The Water absorption decreased with increment of copper slag up to 60%.
India demand comparatively greater cost at around two or three times the cost of crusher. India has enormous growth in steel and copper industry.
Copper slag can effectively enhance the shear strength because it imparts a high internal friction angle to the soil . Prasad and Ramana (2016) investigated the feasibility of copper slag as ...
Today, we have proud to say that we have designed and develop the frst ever metal chip recovery slag crusher plant in India. To develop the slag crushing plant is the big achievement for Bhupindra Machine Pvt.Ltd.
Flotation is one of the most important methods for recovering copper from copper slag, However, traditional grinding may be over grinding sometimes, resulting in smaller interface difference, which leads to a decrease in the selectivity of flotation. In this study, a sodium carbonate combined with mechanical activation enhanced flotation for …
Abstract. Indian cement industry is facing environmental issue of emission of carbon dioxide (CO2), a greenhouse gas. Blended cements including supplementary cementitious materials are substitute of Portland cement to reduce CO2 emission. The present paper investigates theappropriateness of copper slag (CS) as supplementary …
From study it has been observed that the egg shell powder and the copper slag can't affect much the durability and strength parameters up to 6% and 40% replacement of cement and fine aggregate.
Copper slag consists mechanical and chemical properties that is eligible as the material to be used in production of concrete as a partial replacement as a substitute for aggregates. Mechanical property of copper slag has good sound characteristics, good abrasion resistance and good stability for aggregate use. Here an effort has been completed to …
Disintegration of vertically pumped slag melt, separation of metallic and graphite inclusions, and subsequent fine crushing of slag droplets are carried out by means of tangential and angular water-jet blows of the toroidal water blast generated in the diffusor (2) of the vertically located hydro-vacuum plant (1).
Copper slag showed a significant effect on reduction of chloride penetration and increased in quality of concrete. Sulfate immersion increases the weight but a decline in compressive strength. This study recommends copper slag as a sustainable material to develop high strength self-compacting concrete (HS-SCC).
To determine slag properties and the factors influencing these properties for optimization of operating conditions in the copper flash smelting process, the composition and microstructures of the …
The utilization of solid waste is the challenge for the civil and environmental engineers to utilize the waste from different industry to excel the sustainable development, and in the same time, it is matching with the cost concern of the present materials. Copper slag is a by-product obtained during smelting and refining of copper. The waste copper …
To address these challenges, recycling and repurposing of copper slag waste using innovative technologies should be considered, creating a resource for a circular economy. This paper presents a review of copper slag production and its potential as a world resource for cobalt and copper metals.
