The annual amount of copper slag in Japan is two million tons. 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
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.
#0183;#32;This study on the application of copper slag as fine aggregate for concrete has been started with the expectation of large amounts of consumption. Many researchers have already found it possible to use a copper slag as a concrete aggregate. However, it also has been clear that the concrete with copper slag has some problems.
In this experiment a step is taken to reduce the use of fine aggregate in the concrete with copper slag. The fine aggregate is partially replaced with copper slag for 10%, 20%, 30%, 40% and 50%.
mixes with copper slag gave concrete with adequate properties, with the optimal sand replacements by watercooled copper slag overall being in the region of 3060%. Based on the results watercooled copper slag can be considered to be a suitable candidate for the partial replacement of fine aggregate in concrete.
[1]. Copper slag, which is the waste material produced in the extraction process of copper metal in renery plants, has low cost and its application as a ne aggregate in concrete production have many environmental benets such as waste recycling and solves disposal problems.
Various mortar and concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mixture) to as fine aggregates replacement.
Jan 01, 2019#0183;#32;Utilization of high volume Copper Slag (CS) in concrete is the aim of present work. This study leads towards cleaner production; by utilizing industrial waste CS. The objective of the present paper is to make High Strength Concrete (HSC) by utilizing CS as Fine Aggregate (). The work was carried in two phases.
In this work, an extensive study using copper slag has been carried out to investigate strength, workability and durability. Copper slag is an industrial byproduct material produced from the process of manufacturing copper. For, tonnes of
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.
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 10 of sand used in concrete.
Many researchers have investigated worldwide on the possible use of copper slag as a concrete aggregate AlJabri et al (2009, 2011) investigated the performance of high strength concrete made with copper slag as a replacement for fine aggregate at constant workability and studied the effect of super plasticizer addition on the properties of
Sep 19, 2017#0183;#32;When Copper is being extracted from its Ore, a significant amount of unusable residue is separated called as Copper Slag. This Slag more or less possesses the properties of copper upto some extent. Therefore it can be said to have more strength o...
replacement for fine aggregate in concrete increases the density of concrete. 3. Hence, 40% replacement of copper slag is the optimum proportion for replacing fine aggregate.

#0183;#32;Copper slag, which is the waste material produced in the extraction process of copper metal in refinery plants, has low cost and its application as a fine aggregate in concrete production reaps many environmental benefits such as waste recycling and solves disposal problems.
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 cement/slag/water ratio of 1/2/, the ball milled slag gave a higher strength. The effects of using several
25% addition of copper slag as fine aggregate in concrete gives more strength compare to 30% addition of copper slag as fine aggregate in concrete. REFERENCES. Khanzadi M, Behnood A. Mechanical properties of highstrength concrete incorporating copper slag as coarse aggregate, Construction Build Mater Vol. 23, Issue 6, Jun. 2009, pp. .
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
Effects of Copper Slag as a Replacement for Fine Aggregate on the Behavior and Ultimate Strength of Reinforced Concrete Slender Columns used. Table 2 shows the mix design quantities. The mix constituents were weighed in separate buckets and mixed in a rotating drum in accordance with the American Society for Testing and Materials (ASTM
Copper slag is one among various sustainable materials having a promising future as a substitute for river sand. This article presents a study on identifying the optimum percentage of copper slag to be used as a fine aggregate by partially replacing sand in the making of the concrete.
#0183;#32;The objective of the present study is to utilize high volume copper slag ( ) 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 .
Jul 01, 2017#0183;#32;The present work focuses on assessing the viability of applying blasted copper slag, produced during abrasive blasting, as fine aggregate for Portland cement concrete manufacturing, resulting in an alternative and safe disposal method. Leaching assays showed no toxicity for this material.
