Use of copper slag in concrete industry as replacement of cement or/and fine aggregates can have the benefit of reducing the costs of disposal and minimising environmental pollution 1 2 . Little research work has been conducted to investigate the potential use of copper slag as fine aggregate on the properties of normal concrete. Akihiko and
Many countries are witnessing a rapid growth in the construction industry which involves the use of natural resources for the development of the infrastructure. In order to reduce dependence on natural aggregates as the main source of aggregate in concrete artificially manufactured aggregates and artificial aggregates generated from industrial wastes provide an alternative for the

Baby et al. 5 conducted investigations to study the performance of concrete by substituting natural sand with copper slag as fine aggregate. In this study M40 grade concrete was evaluated.
This project 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 refining of copper such that each ton of copper generates approximately tons of copper slag. Copper slag is one of the materials that is considered as a waste which could have a
This paper present results of experimental investigations carried out to evaluate effects of replacing aggregate coarse and fine with that of slag on various concrete properties In this study concrete of M20 and M30 grades were considered for a replacements of 0 25 35 45 55 65 and 75 of aggregates Fine by slag .
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 10 100 of sand used in concrete. For each concrete mixture six 150mmx150mmx150mm cubes three 300mmx150mm dia. cylinders and three 100mmx100mmx500mm prisms
Copper slag has an excellent byproduct which retains its original properties. The main objective is to encourage the use of these seemingly waste products as a construction material. In this paper the effect of using copper slag as a fine aggregate on properties of cement mortars and concrete
This paper presents results from an experimental investigation carried out to 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.
Various studies have been conducted to reduce effect on environment using byproducts like copper slag as partial replacement of fine aggregate is one of the best method in reducing the impacts. Different researchers have also revealed numerous uses of copper slag as a replacing agent in determining the strength of concrete.
The use of copper slag as a replacement for fine aggregate in construction will reduce damage to the environment due to the waste resulting from the copper manufacturing process and help in saving natural resources. In this research the use of copper slag as a replacement for fine aggregate is investigated. Three
In this work we were use Ordinary Portland Cement of 53 grade (Ultra Tech brand) whose properties are explained in Table 1. Natural river sand was used as the fine aggregate and copper slag is used as its replacement. As per IS the natural river sand which is well graded and which comes under zone2 was used as fine aggregate in the
Table 2 Chemical composition (wt ) of blast furnace slag Aggregates Natural siliceous sand having a fineness modulus of and a specific gravity of was used as fine aggregate. The coarse aggregate was a crushed dolomite with a maximum nominal size of 18 mm with a specific gravity of and a crushing modulus of 23 percent.
Paper by Grace Construction and Product Company 1 found that GGBFS was first used in lime mortar production as early as the 1700 s. In Germany it has been interground with Portland cement since 1892 and in other parts of the world it has been added to con crete as a separate constituent since the early 1950 s.
The use of Granulated BlastFurnace Slag (GBFS) as an aggregate in cement mortar and concrete provides environmental as well as economic benefits. Many steel industries in India are supplying GBFS as an alternative to sand.
suitability of the slag for use as fine concrete aggregate from the point of view of gradation. Concrete was made with a mix design of 1 3 (1 part cement parts sand and 3 parts coarse aggregate). The cement used was CEM I Portland cement strength class 52 5N obtained from Hanson UK (brand name Castle High Strength 52 5).
Copper slag as fine aggregate Copper slag has the high toughness so it can be used to partially replacing the fine aggregate. The proportions by weight of copper slag added to concrete mixtures were as follows 0 10 20 30 40 50 60 75 and 100 . 11 Table 6. Mix ratio 2 Cement Water Fine aggregate Coarse aggregate
This paper presents the results of an experimental investigations carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate (sand) was partially replaced with class F Fly ash. Fine aggregate was replaced with five percentages (10 20 30 40 50 ) of class F Fly ash by weight.
The copper slag has been used for cement material sand blasting reclamation and so on. However most of the copper slag is stacked high as waste since the production exceeds demand. This study on the application of copper slag as fine aggregate for concrete has been started with the expectation of large amounts of consumption.
