Copper Slag Copper slag produced during the matte smelting and refining of copper ore, during which, the iron present in the copper concentrate combines chemically at 1200°C with silica present in flux materials such as river sand/silica sand/ quartz fines to form iron silicate, which is termed as copper slag. The copper slag thus generated is ...
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 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)
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
PDF | 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 ...
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 (AlJabri et al., 2009), increased the compressive and flexural strength of .
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
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 ...
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
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 .
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.
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
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.
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 ...
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.
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.
concrete. Partial replacement with copper slag also serves as a solution for the disposal of solid waste. REFERENCES 1. Abdull (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 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.
proportions of copper slag replacement with sand of 0 to in concrete. It concluded that the maximum compressive strength of concrete increased by 55% at 40% replacement of fine aggregate by copper slag and flexural strength of concrete at 28 days 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.
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
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.
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 ...
