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)
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
maximum at 20% replacement of copper slag and is the optimum value for 7days curing and 28days curing 5. Split tensile strength for the cylindrical specimens is maximum at 40% of replacement of copper slag for 28days curing. 6. The flexural strength of copper slag concrete is also maximum at 40% replacement of copper
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
Ariño and Mobasher (1999) prepared mortar specimens containing up to 15% copper slag as a cement replacement with constant water to cementitious solids ratio of The compressiontest results indicated that copper slag concrete was significantly stronger but more brittle than ordinary Portland cement concrete.
The slump of the concrete incorporating the copper slag as fine aggregate increased as more natural sand was replaced by copper slag. Maximum slump obtained was 40mm which occurred at the copper slag replacement as compared to slump of concrete mix. In general, it can be concluded that addition of copper slag

copper slag. It was observed that flexural strength at 28 days is higher than design mix (without replacement) for 20% replacement of fine aggregates by copper slag, the flexural strength of concrete increased by 14%. It was found that compressive strength and flexural strength is increased due to high toughness of copper slag. 3.
Abstract: This research studies the use of waste copper slag as a cement replacement in highperformance concrete (HPC). To obtain two level of fineness, the copper slag was milled using a ball mill. A mixture was prepared with different percentages of copper slag ranging from 0% to 40% in steps of 10%. To obtain the
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 .
As the percentage of Copper slag increases the density of concrete was increased. Density was increased by7% due to replacement of fine aggregate at .Maximum modulus of elasticity of copper slag concrete increased by % at 40% replacement of fine aggregate, and up to 60% replacement, concrete gain more modulus of elasticity
Chittimemu Siva, and Divya Anusha Naidu : Evaluating the Strength Properties of Concrete by Partial Replacement of Sand with Copper Slag a cementations material. Although it has successfully been used in ground form as a concrete mineral admixture in Canada, Europe,
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
Application of copper slag in concrete as a replacement material investigates the possibility of reducing the environmental impact. Copper slag is granular and has similar properties to that of sand [4]. Velumani and Meswari studied on Mechanical and Durability Properties of RC Beams Using Copper Slag as Fine Aggregate in Concrete.
Properties And Effects Of Copper Slag In Concrete 46 PROPERTIES AND EFFECTS OF COPPER SLAG IN CONCRETE M. V. PATIL Applied Mechanics Department, National Institute of Technology, Surat, Gujarat Abstract: Copper slag is a byproduct obtained during matte smelting and refining of copper. This work reports an
PDF | This paper presents the experimental results of an ongoing project to produce concrete with copper slag as a fine aggregate. Sustainability and resource efficiency are becoming increasing ...
This paper reports the effect of concrete using copper slag as fine aggregate replacement. In this project work, the concrete grade M40 was selected and IS method was used for mix design. The properties of material for cement, fine aggregate, coarse
experiment result the geopolymer with 40% replacement of copper slag improve the %, % and % at 28 days compressive strength, split tensile and flexural strength is comparison the geopolymer concrete without copper slag. The water is absorbent durability of geopolymer concrete.
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.
These applications utilize only about 15% to 20% of copper slag generated and remaining material is dumped as a waste. In order to reduce the accumulation of copper slag and also to provide an alternative material for an approach has been done to investigate the use of copper slag in concrete for the partial replacement of sand.
increased with addition of copper slag with concrete. Keywords — copper slag, concrete, durability, replacement, compressive strength. I. INTRODUCTION The utilization of industrial waste or secondary materials has encouraged the production of cement and concrete in .
replacement of sand by copper slag and GGBS. The concrete cubes were cast for different replacement level at an interval of 20 percent to determine compressive strength of concrete at different level of fine aggregate with copper slag, GGBS and Msand. II. PROPERTIES OF MATERIALS A. Cement A powdery substance made by calcining lime and
use of copper slag as a replacement for fine aggregate is investigated. Three slender reinforced concrete columns of 150x150x2500mm were tested for monotonic axial compression load until failure. The concrete mix included ordinary Portland cement, fine aggregate, 10mm coarse aggregate and copper slag. The ratios of copper slag to fine aggregate ...
Studies on use of Copper Slag as Replacement Material for River ... Download PDF ... It is therefore suggested that the copper slag can be used for plastering of floorings and horizontal up to 50 % by mass of the fine aggregate, and for vertical surfaces, such as, brick/block walls it can be used up to 25 %.
