PDF | The use of a Chilean copper smelter slag in the manufacture of cement mortars was studied. Copper slag was characterized from the chemical, mineralogical and size distribution point of view.
Two types of slag can be produced: an air-cooled copper slag with light black color and a glassy appearance, and granulated copper slag which is porous with a vesicular structure. 26 The specific gravity of copper slag varies as a function of the iron content, between 3.2 and 3.8 kg/m 3, and its water absorption is typically very low (<0.2 wt ...
The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route.
From the fig.7 it was observed that the copper slag admixed concrete showed higher corrosion rates than normal concrete in various percentages of replacements. The corrosion rate of copper slag admixed concrete increases as percentage of copper slag increases. The corrosion rate can be controlled by coating the bar with Zinc Phosphate paint.
Oct 12, 2019· 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.
The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries, particularly in areas where a considerable amount of copper ...
SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore, Its chemistry and morphology depends on the metal being produced and the solidification process used. Slags can be broadly categorized as ferrous (iron/steel) and non-ferrous (copper, lead/zinc) depending on the industry from which ...
Aug 20, 2014· Abstract. This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering.
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. In general, the spent copper slag is suitable to be used as a fill material for land reclamation.
Can The Copper Slag Be Used Instead Of Sand In ConcreteHow to Use Slag eHow. How to Recycle Copper Slag. has become a popular and cheap alternative to sand for use in concrete is a form of sustainable concrete that can b
Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece. Copper slag is just one of many different materials that may be used as abrasive grit.
Use of Copper Slag and Cement By Pass Dust as Cementitious Materials. 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.
Copper Slag has similar properties to sand and is a very effective substitute during monsoon (rainy) season. Further, Copper Slag is also used in the production of cement, mortar, and concrete as a raw material for clinker, cement replacement, coarse and fine aggregates.
Hi. Copper slag is used in High Performance Concrete. By using the copper slag in concrete as the partial replacement for fine aggregate i.e., sand, the ...
study the potential use of copper slag as fine aggregate on the strength of both normal and high strength concrete. Concrete mixtures were prepared using different proportions of copper slag as partial and full replacement of fine aggregate. The percentage of copper slag added by weight ranged between 10- of sand used in concrete.
While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here. The use of slag cement has demonstrated long-term performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased durability.
Apr 19, 2018· Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or a...

Copper slag admixed mortar and concrete showed a lesser amount of leaching than solution due to the complex formation with cement mortar. Hence, copper slag can be used (2.5%) in raw mix for OPC and (35%) in manufacture of PSC. The material does not have any adverse impact on .
While producing copper the anode, a slag with rich iron and moderate silica content is also generated. The chemical analysis of the slag indicated that its matrix is compatible with the cement system and can be used in the manufacture of OPC. The copper slag has been found to contain high iron oxide and may be used as a source of iron in the ...
The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries, particularly in areas where a considerable amount of copper slag is produced. This paper reviews the characteristics of copper slag and its effects on the properties of cement, mortars and concrete.
The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date. One of the greatest potential applications for reusing copper slag is in cement and concrete .
