Copper slag is a byproduct obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date.
proportions of copper slag replacement with sand of 0 to in concrete. It concluded that the maximum compressive strength of concrete increased by 55% at 40% replacement of fine aggregate by copper slag and flexural strength of concrete at 28 days is .
purpose and the copper slag is replaced for fine aggregate. To provide the alternative materials is sand and cement. Copper slag is used the building material and blasting media manufactured from copper slag bring less harm to peoples and environment than sand. It is most rigid health and ecological.
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.
shown higher value at 40% replacement of fine aggregate using copper slag. So it is recommended that 40% of fine aggregate can be replaced by copper slag. : [1] Gorai B, Jana RK, Premchand. ―Characteristics and utilization of copper slag—a review.‖ Resource Conservation and Recycling, 2003;39, –313.
• Copper slag is a very good alternative material for fine aggregate it can be replaced upto 40% with fine aggregate so that it gives highest strength at 28 days compare to normal concrete with M20 mix. • By replacing fine aggregate with 40% of copper slag gives the strength %, .
Copper slag can be used as an alternative for cement or fine aggregate in concrete. In this study the fine aggregate in ECC is partially replaced by copper slag. Five specimens were made by varying the amount of fine aggregate replacement from 0% to 50% (at 10% intervals). The optimal content of copper slag in
Use of copper slag as a replacement for fine aggregate in reinforced concrete slender columns A. S. Alnuaimi Department of Civil and Architectural Engineering, Sultan Qaboos University, Oman Abstract The use of copper slag as a replacement for fine aggregate in construction will
study encouraged the use of industrial byproduct or waste copper slag as replacement material of fine aggregates in concrete. Mix proportion has to be done for M25 grade of concrete with water cement ratio The fine aggregate is replaced with copper slag .
of the major materials is copper slag (CS), GGBS (Ground Granulated Blast Furnace Slag) and Msand (Manufactured sand). Using different proportion of these copper slag and GGBS along with sand the required concrete mix can be obtained. stone sand, crusher sand and crushed fine aggregate.
about copper slag is shown in Table The size of the particle is of the order of sand and can be used as a fine aggregate in concrete. To reduce the accumulation of copper slag and also to provide an alternative material for sand and cement, an approach has been done to investigate the use of copper slag in
Jan 16, 2017· Partial replacement of Fine aggreggate by Copper Slag and Cement by Fly Ash 1. 1 Replacement Of Fine Aggregate By Copper Slag And Cement By Fly Ash Ammini College Of Engineering, Mankara, Palakkad 1. INTRODUCTION GENERAL Concrete is the man made material widely used for construction purposes.
Aug 12, 2019· In the first phase, the fine aggregate is replaced with copper slag in different percentages of 20%, 40%, 60%, 80%, and . In the second phase, the cement is replaced with different percents of Nano silica 1%, 2% and 3%.Mix proportions of this study in Table 1. Table 1. Mix Proportions of Hsc (M80). Mix CS % Cement kg/m 3 Silica Fume

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 refining of copper such that each ton of copper generates approximately tons of copper slag.
fine aggregate by copper slag, Concretemixes, viz. Conventional concrete mixes with varying percentages of copper slag (10, 20, 30 and 40%) as fine aggregate replacement material were investigated. The compressive strength test was carried out on 4 concrete mixes at the ages of 7, 14 and 28 effect of
