investigations on the influence of partial replacement of sand by copper slag on the mechanical properties of concrete. M30 grade concrete was designed using copper slag, partially replacing the fine aggregate The fine aggregate was replaced by copper slag at various percentages ranging from 0%, 10%, 20%, 30%, 40%, 50%, 60%, 80% and .
The degree of replacement of natural fine aggregates with copper slag was put at 20%, 40%, 60%, 80%, and by volume. A control mix containing natural fine aggregates were also prepared for comparison. The strength and durability of slag cement concrete mixes having varying copper slag content were analyzed based on the results.
The use of theses industrial waste as substitute of cement, control the emission of CO2 and also control the environmental problems associated with its dumping. Industrial wastes, such as copper slag, blast furnace slag, granulated phosphorus slag and steelmaking slag are being used as supplementary cement replacement materials.

This paper deals with the experiments conducted to study the effect of copper slag, GGBFS (Ground Granulated Blast Furnace Slag), metakaolin on the properties of concrete. While GGBFS and metakaolin are used as partial substitutes for cement, copper slag is used as a partial substitute for fine aggregate. This study investigates the mechanical strength of the concrete in terms …
Smelter slag is initially deposited in piles. These slag piles range in surface area from one to 75 acres, and in height from three to 45 meters. Slag is associated with smelter operations, which may or may not be co-located with the mines. Copper slag can be used either as sandblast grit or an admixture in concrete.

Several researchers have investigated the use of copper slag in the production of cement, mortar and concrete as raw materials for clinker, cement replacement, coarse and fine aggregates. This paper reports on some experimental investigations on the influence of partial replacement of sand by copper slag on the mechanical properties of concrete.

Utilization of modified copper slag activated by Na2SO4 and CaO for unclassified lead/zinc mine tailings based cemented paste backfill Author: Qiusong Chen, Yunbo Tao, Yan Feng, Qinli Zhang, Yikai Liu Source: Journal of environmental management 2021 v.290 pp. 112608 ISSN: 0301-4797 Subject:
Slag cement has actually been used in concrete projects in the United States for over a century. Its earliest use was documented in 1774, when it was combined with slaked lime and used as a mortar.This cement was first used commercially in Germany in the 1860s, and it was such a success that engineers in 1889 decided to build the Paris underground metro using slag-lime cement.
copper slag in concrete production. Copper slag is one of the by-product materials from the copper smelting. In Indonesia, around 400,000 tons of copper slag are produced per year by Freeport Company and Newmont Company [3]. This number is a motivation for the researchers to study the copper slag as aggregate or cement replacement in concrete.
concrete. The use of copper slag in the concrete industry as a replacement for cement can have the benefit of reducing the costs of disposal and help in protecting the environment. Despite the fact that several studies have been reported on the effect of copper slag replacement on the properties of

The workability of concrete was assessed based on the measured slump of fresh concrete. It is clear from Table 2 that the workability of concrete increases significantly with the increase of copper slag content in concrete mixes. For the control mixture (i.e. Mix 1), the measured slump was 28 mm whereas for Mix 8, with replacement of ...
1. Copper slag: Copper Slag has shown promising results as a replacement in fine aggregate. Studies have indicated a generation of 33 million tonnes of copper slag worldwide. As reported by a recent study conducted in India, 50% copper slag can be used as a …
For this above-mentioned replacement percentage, M20 grade concrete is used with a water–cement ratio of 0.48. For 5% replacement of pumice, the amount of copper slag replaced is 5% with fine aggregate and the amount of pumice replaced is 5% with coarse aggregate.
The optimum copper slag and cement by-pass dust to be used is 5%. In addition, it was determined that using cement bypass dust as an activating material will work better than using lime. Additional studies should investigate the strength and durability when copper slag and cement by-pass dust are used in concrete mixes.

copper slag is produced every year. Also, the production of approximately 0.36, 0.244, 2.0, and 4.0 million tons of copper slag is reported in Iran, Brazil, Japan and the United States, respectively. Utilization of copper slag in applications such as substitute of fine …
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-2 and SA-2. Copper slag blasting media/grit is manufactured of the granulated slag of copper refineries, and used for blast-cleaning of metal surface.
