The percentage of copper slag used for replacement of river sand are 0, 25, 50 and 75 %. Cement sand mortar joint thickness of 10 and 15 mm. Plaster ability of use of copper slag for partial replacement material for river sand. Use of copper slag as replacement material for river sand in cement concrete (0, 25, 50, 75 and 100 %)
The failure patterns of copper slag and river sand are however found to similar when tested under similar loading conditions and same longitudinal and transverse reinforcement. 7. From the obtained experimental results it is shown that copper slag with replacement in place of river sand showed an improved structural performance.

The vibration exciter and the screen box frame of S5X Vibrating Screen use modular structures If there is a need for replacement the modular vibration exciter can be taken down from the ...
Therefore, copper slag is expected The effect of copper slag replacement as fine aggregates on the to have good potential to produce high quality pozzolans. workability and density of high performance concrete is presented Tests to determine specific gravity and water absorption for in Table 2 for different proportions of copper slag.
Copper Slag (CS) is produced as waste from roasting of copper, in which sulphur (as SO 2 ) is eliminated. CS was used as fine aggregate (up to 30%) in the design of bituminous mixes like Bituminous Macadam, Dense Bituminous Macadam. Bituminous Concrete and Semi-Dense Bituminous Concrete. Mechanical properties of mix such as Marshall stability, Indirect Tensile Strength was determined.

50% of copper slag as sand replacement yielded comparable strength with that of the control mix. However, further additions of copper slag caused reduction in the strength due to an increase of the free water content in the mix. Ramzitaha et al.(2011),In this, Various mortar and concrete mixture were prepared with different proportion of copper ...
1.1 Copper Slag as a Sand Replacement:- Copper Slag as a Sand Replacement can be used due to the following reasons: It has a high Compressive strength which is equal to that of Fine Aggregate with similar diameter. Copper Slag is a non-degradable matter; it is creating an environmental problem so when used as a Replacement for ...
of copper slag and sand from 0 to . The result showed that workability increases with increase in percentage of copper slag. Maximum Compressive strength of concrete increased by 34 % at 20% replacement of fine aggregate with copper slag, and up to 80% replacement of copper slag, concrete gain more strength than normal concrete strength.
40–50% copper slag as a sand replacement yielded comparable strength to that of the control mixture. However, addition of more copper slag resulted in strength reduction due to the increase in the free water content in the mix. Also, the results demonstrated that surface water absorption decreased as copper slag content increases up to 50% ...
The fine aggregate (usually Sand preferred) is basically chemically inert materials used for particles smaller than 4.75mm, contains particles in the size range 75µm to 4.75mm, are partially or fully can be replaced by Crushed sand (Manufacture sand), Crusher dust (Quarry dust), Washed bottom ash, Granulated blast furnace slag, Copper slag, etc.

This study aimed to investigate the suitability and cost-benefit of using copper tailings as partial replacement of sand in concrete production. The study was motivated by the accumulation and non-use of copper tailings in dams among them tailing dam 25 also known as TD 25 in Kitwe city of the Copperbelt province in Zambia that take up approximately 111 hectares of unused land.,Laboratory ...
Zambia is African largest producer of copper, ... Copper slag as sand replacement The use of copper slag as sand substitution improves the strength and durability characteristics of high strength concrete up to 50% replacement level (Al-Jabri et al., 2009), increased the ...
Brinda. D et al [4] investigated on various corrosion and durability tests on concrete containing copper slag as partial replacement of sand and cement. In this paper, M50 grade concrete was used and the tests were conducted for various proportions of copper slag replacement with sand of 0% to 60%, cement 0% to 20% and combination.
It is recommended that 40 wt% of copper slag can be used as replacement of sand in order to obtain HPC with good properties.6. It should be noted that further research work is needed to explore the effect of copper slag as fine aggregates on the properties of concrete with different cement types, silica fume sources and the degree of fines.
