study the potential use of copper slag as fine aggregate on the strength of both normal and high strength concrete. Concrete mixtures were prepared using different proportions of copper slag as partial and full replacement of fine aggregate. The percentage of copper slag added by weight ranged between 10100 of sand used in concrete.
The objective of the present study is to utilize high volume copper slag i.e. 100 as a replacement to fine aggregate and partially replacing cement with Nano silica. The work is carried out in two phases. In the first phase, the fine aggregate is replaced with copper slag in different percentages of 20, 40, 60, 80, and 100.
This paper investigates the technical feasibility of using copper slag as fine aggregate replacement in ultra high performance concrete UHPC. The studies demonstrated that it is possible to produce UHPC having compressive strength greater than 150 MPa by incorporation of copper slag.
This paper presents the results from an experimental testing program conducted to investigate the performance of high strength concrete made with copper slag as a fine aggregate at constant workability. The effect of admixture addition on the properties of concrete mixtures made with different proportions of copper slag is also discussed. 2.

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.
Keywords copper slag, fine aggregate, concrete, strength, workability, density. 1 Introduction Aggregates are considered one of the main constituents of concrete since they occupy more than 70
Looking into literature, copper slag was investigated by several researchers as fine or coarse aggregate replacement and cement replacement in high strength concrete HSC and high performance
Good performance of copper slag as fine and coarse aggregates in normal concrete is the basis for researchers to evaluate its possible use in producing special concrete such as selfconsolidating concrete Shoya et al., 2003, highperformance concrete AlJabri, 2006 and highstrength concrete Khanzadi and Behnood, 2007.
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. Three masonry wall panels of dimensions 1 1 m were plastered.
This paper investigates the fresh and durability properties of the highperformance concrete by replacing cement with 15 Silica fume and simultaneously replacing fine aggregates with 25, 50, 75 and 100 copper slag at wb ratio of 0.23. Five mixes were analysed and compared with the standard concrete mix. Fresh properties show an increase in the slump with the increase in the quantity of
Although some researches have been worked for high strength concrete to replace traditional sand with copper slag as fine aggregate 11 12131415 or coarse aggregate 16, few studies have

In previous research work 1, 3, 4,5,7,8,11,15 the authors discusses the performance of copper slag substitution as fine aggregate on the compressive strength, durability, and workability of
This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of fine aggregate on the strength properties. Copper slag is the waste material of matte smelting and rening of copper such that each ton of copper generates approximately 2.5 tons of copper slag.
Performance of Copper slag and ferrous slag as partial replacement of sand in Concrete slag by high power water jet, making 100 glassy slag granules of 0.4 mm size. Indian FS indicated that replacement of fine aggregate sand by copper slag
This research study was conducted to investigate the performance of high strength concrete HSC made with copper slag as a fine aggregate at constant workability and to study the effect of superplasticizer addition on the properties of HSC made with copper slag.
Motivated by the sustainable production perspective, a laboratory testing program is exercised to ascertain the feasibility of utilizing copper slag in place of the natural fine aggregate in concrete. Totally, fifteen concrete mixtures were prepared to incorporate copper slag in place of the fine aggregate in concrete. The attributes of concrete specimens made with varying proportions of
conducted to investigate the performance of high strength concrete made with copper slag as a fine aggregate at constant workability and to study the effect of super plasticizer addition on the properties of HSC made with copper slag. The water content was adjusted in each mixture in order to
