In the present study, the combination of fly ash, silica fume, and copper slag as partial replacement is used for both cement and fine aggregate. Since superplasticizer is a must to be used if copper slag is used as substitute for fine aggregate, it is used in concrete making. Creep is one of the major problems faced in large concrete girder.

One of the greatest potential applications for reusing copper slag is in cement and concrete production. Many researchers have investigated the use of copper slag in the production of cement, mortar, and concrete as mixed with lime stone powder, dust, cement replacement, use as partial replacement of coarse, and fine aggregates.

replacement by air cooled copper slag at 20 and 40% volume replacements as well as fine aggregate replacement by copper slag at 20 and 40% levels per volume. It studied gas permeability of copper slag concrete (which was significantly lower or comparable to that of the control mix), chloride ingress (which was found to be significantly lower

Moura et al. 11 employed copper slag as an additive in concrete, and they observed increased mechanical strength, reduced porosity and carbonation for concrete samples. AlJabri et al. 12 also submitted that the substitution of sand with copper slag improved the strength and durability properties of high strength concrete.

The presence or absence of copper slag fine aggregate and fly ash replacement was employed as an experimental parameter. The results suggest that the corrosion of horizontal steel bars in the upper part of the column concrete specimens was adversely affected, even in the case of OPC specimens with relatively lower bleeding water.

when copper slag was used to replace fine aggregate, up to 40% copper slag replacement, the strength of concrete was increases while the surface water absorption decreases. They also observed that when more than 40% of copper slag is used, the

By conducting the constantcurrent accelerated corrosion test of reinforced concrete with different copper tailing in the brine environment of the Qinghai province, the corrosion rate, crack width, and corrosion potential of the steel reinforcement with copper tailings were studied, and the following conclusions were obtained:

This paper manages the trial Investigation on concrete by partial replacement of fine aggregate with copper slag to improve the quality strength parameters, for example compressive strength, split tensile strength, and flexural strength of the M25 and M30 grade of concrete. Here the fine aggregate partially replaced with copper slag in concrete with 5%, 10%, 15% 20% by weight of fine ...

copper slag on the compressive strength of cubes, split tensile strength of cylinders and flexural strength of beams are evaluated in this study. Copper slag is obtained as waste product from the sterlite industries. Investigations were carried out to explore the possibility of using copper slag as a replacement of sand in concrete mixtures.

Previous studies have shown that copper slag, which is less abundant in comparison to copper tailings, can enhance the mechanical and durability properties of mortar and concrete. Ayano and Sakata 10 observed higher longterm compressive strength in concrete mixtures containing copper slag. They also noticed that these mixtures displayed no significant sulfate induced deterioration, and the rate of .
