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.
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.
concrete. Partial replacement with copper slag also serves as a solution for the disposal of solid waste. REFERENCES 1. Abdullah (August 2009), "Copper slag as sand replacement for high performance concrete", Cement and Concrete Composites, 31 (7), pp 483488 20 21 0 20 40 m 2 % of Copper Slag 20 21

copper slag as a substitution replacement material of sand. Copper slag which is an industrial waste product can be used as replacement for cement with sand and contributes to the increase in various mechanical properties of concrete. Copper slag can be used up to 30% but when used ahead of 50% results in decrease in strengths. [13]
copper slag in concrete. At present about 33 million tonnes of copper slag is generating annually worldwide among that India contributing 6 to million tonnes. 50 % copper slag can be used as replacement of natural sand in to obtain mortar and concrete with required performance, strength and durability. (Khalifa S. AlJabri et al 2011)
[6] Patil, Patil Veshmawala observed the Performance of Copper Slag as Sand Replacement in concrete was used and various tests like compressive, flexural, split tensile strength ...
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.
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.
AlJabri 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 ...
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...
Granulated Copper Slag as a patial replacement for sand. r Fifteen concrete mixes with different proportions of Granulated 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.
partial replacement of fine aggregate with copper slag. Addition of copper slag increases the density of concrete thereby increasing the selfweight, so that it can be used for high density concrete production. Economic Feasibility Geopolymer concrete (GPC) manufactured using industrial waste like fly ash, GGBS and copper slag is
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 .
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
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
Copper Slag as a Sand Replacement can be used due to the following reasons: It has a high Compressive strength which is equal to that of Fine Aggregate with similar diameter. Copper Slag is a nondegradable matter; it is creating an environmental problem so when used as a Replacement for
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.
Experimental Investigation of Copper Slag Replacement of Fine Aggregate Ppt Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Concrete Experimental investigation of copper slag replacement of fine aggregate
Therefore, it is recommended that up to 40–50% (by weight of sand) of copper slag can be used as a replacement for fine aggregates in order to obtain a concrete with good strength and durability ...
strength properties of copper slag as a partial replacement of sand at different levels (0%, 20% and 40%). Copper slag is a byproduct 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,
Copper slag is a byproduct 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, roadbase construction, railroad ballast, asphalt pavements.
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.
Properties And Effects Of Copper Slag In Concrete 47 Fineness Modulus The fineness modulus of coarse aggregates (20 mm 10 mm), sand and copper slag are,, and respectively. Table to shows the fineness modulus of 20 mm, 10 mm coarse aggregates, sand and copper slag respectively.
