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
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 ...
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.
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.
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
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
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.

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 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)
replacement have been compared. The results indicated that geopolymer concrete with 40% copper slag as fine aggregate replacement showed an improvement of 17.5%, 13.94% and 22.72% in the 28th day compressive strength, splitting tensile strength and flexural strength respectively in comparison with the geopolymer concrete
Properties And Effects Of Copper Slag In Concrete 46 PROPERTIES AND EFFECTS OF COPPER SLAG IN CONCRETE M. V. PATIL Applied Mechanics Department, S.V. National Institute of Technology, Surat, Gujarat Abstract: Copper slag is a by-product obtained during matte smelting and refining of copper. This work reports an
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
"Study of Strength Properties of Concrete by Partial Replacement with Fly Ash and Copper Slag in Cement And Fine Aggregate" G Swathi1, G Dinesh 2 1 Assistant Professor, Civil Engineering Department, Aditya Engineering College, Surampalem, AP. 2Assistant Professor, Civil Engineering Department, Aditya Engineering College, Surampalem, AP. Abstract- For every ton of rpper slag .
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 ...
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 Maheswari studied on Mechanical and Durability Properties of RC Beams Using Copper Slag as Fine Aggregate in Concrete.
possibility of using copper slag as a replacement of sand in concrete mixtures in various percentages ranging from 0%, 20%, 40% 60%, 80% and . It was observed that, the flexural strength of concrete at 28 days is higher than design mix (without replacement) for 40% replacement of fine aggregate by Copper slag. Atul et al
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
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
