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.
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.
Abstract: This research studies the use of waste copper slag as a cement replacement in high-performance 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
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
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.
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 %.
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
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 .
experiment result the geopolymer with 40% replacement of copper slag improve the 17.5%, 13.94% and 22.72% 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.
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 .
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 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] e-ment 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

Abstract- For every ton of rpper slag .
of the concrete. The use of copper slag in the concrete industry as a replacement for cement can have the benefit of reducing the costs of disposal and help in protecting the environment. Despite the fact that several studies have been reported on the effect of copper slag replacement on the properties of
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 M-sand. 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 6.5 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. Al-Jabri et al 2011)

quality of the washed copper slag containing concrete would be suggested at the end of this project. 1.1 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 .
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
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 ...

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 0.4. The compression-test 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
