The blasting media manufactured from copper slag brings less harm to people and environment than sand. The product meets the most rigid health and ecological standards. Construction. 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.
Partial Replacement of Copper Slag as Fine Aggregate Ambrish E1, Dhavamani Doss S2, ... "Copper slag as sand replacement for high performance concrete", Cement & Concrete Composites, Vol. 31, pp. 483- 488, 2009. [2] Akihiko, Y. and Takashi, Y. "Study of utilisation of copper slag
partial replacement of fine aggregate with copper slag. Addition of copper slag increases the density of concrete thereby increasing the self-weight, so that it can be used for high density concrete production. 4.9. Economic Feasibility Geopolymer concrete (GPC) manufactured using industrial waste like fly ash, GGBS and copper slag is
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.
[6] Patil, Patil & Veshmawala observed the Performance of Copper Slag as Sand Replacement in Concrete.M30 concrete was used and various tests like compressive, flexural, split tensile strength ...
Aug 04, 2018· Granulated blast furnace slag ( GBFS) has been able to replace Sand to the amount of 70%. GBFS is byproduct of steel industry & hence this method is feasible at location where steel plant is located in close proximity. Copper slag is yet another r...
strength properties of copper slag as a partial replacement of sand at different levels (0%, 20% and 40%). Copper slag is a by-product obtained during the matte smelting and refining of copper. In the present investigation it is proposed to study the engineering properties of Copper slag viz. Slump test,
The mix design of M25 grade of concrete gives HPC concrete when replacement of copper slag is 50%. In this case we observed that Copper slag behaves like river sand. When we use bamboo as a replacement of steel, bamboo gain almost same flexural strength compared to steel reinforced concrete.

Copper slag is a by-product obtained during matte smelting and refining of copper. The common management options for copper slag are recycling, recovering of metal, production of value added products such as abrasive tools, roofing granules, cutting tools, abrasive, tiles, glass, road-base construction, railroad ballast, asphalt pavements.
Al-Jabri et al. used copper slag as sand replacement for high performance concrete [6]. AlJabri et al. examined the effect of copper slag as fine aggregate on the characteristics of cement mortar ...
copper slag, and also to scrutinise the following: 1. To find the optimum proportion of copper slag that can be gained maximum strength and that proportion will be used as a replacement substitute material for fine aggregate in concrete. 2. To debrief the physical and chemical properties by use of copper slag for fine aggregate in concrete
Copper slag as sand replacement The use of copper slag as sand substitution improves the strength and durability characteristics of high strength concrete up to 50% replacement level (Al-Jabri et al., 2009), increased the compressive and flexural strength of .
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.
copper slag can be used as a partial replacement for sand as fine aggregate in concrete up to 40% in pavement grade concrete with out any loss of cohesiveness and the compressive and flexural strength of such concretes is about 20% higher than that of conventional cement concretes of the same grade
Granulated Copper Slag as a patial replacement for sand. r Fifteen concrete mixes with different proportions of Granulat-ed Copper Slag ranging from 0% (for the control mix) to were considered. All the mixes were proportioned by the method of absolute volumes considering the specific grav ity of the constituent materials.
It is recommended that 40 wt% of copper slag can be used as replacement of sand in order to obtain HPC with good properties. 6. It should be noted that further research work is needed to explore the effect of copper slag as fine aggregates on the properties of concrete with different cement types, silica fume sources and the degree of fines.
Natural sand, as well as copper slag, was passed through 4.75 mm IS sieve. The specific gravity of natural sand and copper slag was experimentally determined to be 2.62 and 3.43, respectively, by using pycnometer as per BIS:2386 part III-1963, R 2002 . Coarse aggregates (basalt) of size 10 mm and 20 mm having a specific gravity of 2.77 and 2.82 ...
USE OF COPPER SLAG AS A REPLACEMENT FOR FINE AGGREGATE IN CONCRETE. ... M20 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0 to 60 ...
Addition of up to 50% of copper slag as sand replacement yielded comparable High performance concrete Copper slag strength with that of the control mix. However, further additions of copper slag caused reduction in the Waste material strength due to an increase of the free water content in the mix.
using copper slag as a replacement of fine aggregate on the strength properties. M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0% to in concrete. The test results indicate that compressive strength of concrete
The compressive strength of cube specimen for different copper slag content as a replacement of sand at 7, 28, and 56 days curing period respectively is presented below. These results show an increasing profile up to 40% replacement of copper slag and then it shows decreasing profile as more copper slag .
The results indicate that there is a slight increase in the HPC density of nearly 5% with the increase of copper slag content, whereas the workability increased rapidly with increases in copper slag percentage. Addition of up to 50% of copper slag as sand replacement yielded comparable strength with that of the control mix.
Use of copper slag as a replacement for fine aggregate in reinforced concrete slender columns A. S. Alnuaimi Department of Civil and Architectural Engineering, Sultan Qaboos University, Oman Abstract The use of copper slag as a replacement for fine aggregate in construction will
