The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. ... pdf. Strength of Concrete Structure Partial Replacement of Sand by Copper Slag. Priyatam Kumar | H. L. Yadav, 2019.
quality of the washed copper slag containing concrete would be suggested at the end of this project. Copper Slag as a Sand Replacement: Copper Slag as a Sand Replacement can be used due to the following reasons: It has a high Compressive strength which is .
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.
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
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 %.
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
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 ...
copper slag as partial replacement of aggregate to control the amount of bleeding to less than 5 l/m. 2. Studies by Alnuaimi indicated that replac[2005] ement of fine aggregate (sand) by copper slag does not have an adverse effect on the load carrying capacity of the concrete columns. Rojas [2008] had reported that copper slag exhibits

Influence of Copper Slag in Concrete as Partial Replacement for Fine Aggregate N. Vinoth Kumar1 S. K. Divya2 A. Sattainathan Sharma3 1,2,3Assistant Professor 1,2,3Department of Civil Engineering 1,2,3Valliammai Engineering College, Kancheepuram, India Abstract—Concrete is the widely used construction material.
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
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 .
The effect of copper slag replacement as fine aggregates on the workability and density of high performance concrete is presented in Table 2 for different proportions of copper slag. The workability of concrete was assessed based on the measured slump of fresh concrete.
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.

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
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)
PDF | This paper is about the experimental study of the replacement of copper slag for fine aggregate in concrete. In this study, M40 Grade concrete was considered to study the strength of ...
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.
Therefore, it is recommended that replacement of fine aggregates by 40–50% of copper slag (by weight) will produce concrete mixtures with comparable environmental impacts while maintaining feasible durability and strength properties.
