Apr 01, 2000 Many concrete engineers are eager to find fine aggregate sources other than the traditional river and sea sand. Copper slag fine aggregate is expected to be one of the alternatives although the location where the copper slag is available is limited. In this paper, some characteristics of concrete with copper slag will be clarified.
An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of cement mortars and concrete. Various mortar and concrete mixtures were prepared with different proportions of copper slag ranging from 0 for the control mixture to 100 as fine aggregates replacement.
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 slender reinforced concrete ...
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.

Use of copper slag in concrete industry as replacement of cement orand 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
Copper slag is one of the materials that is considered as a industrial waste which can be used in construction Industry. This paper presents the results of an experimental investigation on the properties of concrete using copper slag as partial replacement of fine aggregate.
the copper slag can be alternatively used. 3 Vast quantities of copper slag are produced from manufacturing of copper.In our project we are using the copper slag by replacing natural fine aggregate at different percentage like 0, 20, 40, 60, 80, and 100. B. Objective of the Investigation 1 The use of copper slag in the concrete as a ...
Copper slag, a by-product of copper production, contains large amounts of iron oxide and silicate. It is chemically stable and its physical properties are simil
Reinforced Concrete Slender Columns AS Alnuaimi Department of Civil and Architectural Engineering, Sultan Qaboos University, Al-Khoud, Muscat, Sultanate of Oman Received 6 March 2011 accepted 7 March 2012 Abstract Use of copper slag CS as a replacement for fine aggregate FA in RC slender columns was experimen-tally investigated in this study.
using copper slag as a replacement of fine aggregate on the strength properties. M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0 to 100 in concrete. The test results indicate that compressive strength of concrete
Aug 01, 2008 It was noticed that the use of copper slag as fine aggregate could greatly increase the abrasion resistance of the cement mortar Tang et al., 2000. Hwang and Laiw 1989 evaluated the compressive strength development of mortars and concrete containing fine copper slag aggregate with different water to cement ratios Fig. 4, Fig. 5.
A-2 Copper Slag as Aggregates. Copper slag is a blackish granular material, similar to medium to coarse sand having size ranging from 150 m to 4.75 mm. This aggregate has potential for use as fine aggregate in accordance with provisions of this standard see Fig. 4. Get Price
7. Brindha and Nagan 2011 Durability of copper slag admixed concrete. The strength of concrete increases with respect to the percentage of slag added by weight of fine aggregate up to 40 of additions and 15 of cement. 8. Najimi et al 2011 The performance of copper slag contained concrete in sulphate solution .
Jun 02, 2021 As an interesting discovery on the use of copper slag as a fine aggregate, the author stated that a wide range of research supports the use of Cu slag as a fine aggregate in concrete floors and pavements due to its reasonable hardness . Moreover, the author stated that from an environmental point of view, the Cu slag can be considered as a safe ...
Abstract Since there is a scarcity of fine aggregate throughout the country it is essential to find a replacement of fine aggregate. Our idea is to use copper slag as replacement of fine aggregate.Due to several costs of labours for compaction we can go to self compacting concrete.
