copper slag as fine aggregate on the properties of normal concrete. Akihiko and Takashi 3 investigated the use of slag from copper smelting as a fine aggregate in concrete. From mortar strength tests with a cementslagwater ratio of 120.55, the ball milled slag gave a higher strength. The effects of using several
copper slag as a replacement of fine aggregate on the strength properties and concluded that Maximum Compressive strength of concrete increased by 55 at 40 replacement of fine aggregate by copper slag and flexural strength increased by 14 for 40 replacement.
discussions on water absorption and Acid attack of concrete containing copper slag as partial replacement of fine aggregate in concrete The present study is based on trial mixes and achieving target strength. Mix proportions have been obtained for M30 grade concrete. Then copper slag is
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 100 copper slag replacement as compared to slump of concrete mix. In general, it can be concluded that addition of copper slag
Copper Slag Copper Slag with specific gravity 3.5 and fineness modulus 3.25, bulk density 1710.2kgm3 was used. Fine aggregate Sand Fine aggregate Sand conforming to Grading zone III of IS3831970 having specific gravity 2.65 and bulk density 16472kgm3, fineness modulus 3.29 was used. Coarse aggregate
Mr. zine kiran sambhaji , prof. pankajj B. autade Investigated the effect of copper slag as a fine aggregate on properties of concrete. In this research paper copper slag 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 replace with fine aggregate respectively. The conclusion of the paper is the design m25 grade concrete for 50 replace of CS show the
copper slag concrete w.r.t conventional concrete V. CONCLUSION By our Project, we conclude that strength of concrete increased by the replacement of M-sand by copper slag, saves concrete material cost. Here we are using OPC of 53 grade, Well graded coarse and fine aggregate. 30 copper slag replacement showed Maximum workability.
Use of copper slag in the concrete industry as a replacement for cement andor fine aggregates can has the benefits of reducing the costs of disposal and helps protecting the environment. 3 Copper slag Copper slag is a by-product material produced from the process of manufacturing copper.

presents the experimental results of an on-going project to produce concrete with copper slag as a fine aggregate. The effect of replacing fine aggregate with copper slag on the compressive, flexural and split tensile strength of concrete are studied in this work. It was seen that for design mix 11.663.76 with wc 0.45 and 0 to 60
replacement, CS and FS can be effectively used as replacement for fine aggregate. Further research work is needed to explore the effect of CSFS as fine aggregates on the durability properties of concrete. Keywords By product, copper slag, ferrous slag, compressive strength, concrete
mixes with copper slag gave concrete with adequate properties, with the optimal sand replacements by water-cooled copper slag overall being in the region of 30-60. Based on the results water-cooled copper slag can be considered to be a suitable candidate for the partial replacement of fine aggregate in concrete.

glass fibre reinforced concrete with copper slag as a partial replacement of fine aggregate. The parameters of the study included by replacing the fine aggregate by copper slag with 60 and by varying the volume fraction of glass fibre 0.5, 1 and 1.5. The grade of concrete is M20. The specimens were cured for 7 and 28 days.
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.
