It was found that a 40 wt.% copper slag as FA in concrete improved the compressive strength by 5-8% [Citation 13, Citation 14]. In addition, copper slag as coarse aggregate increased the compressive strength of ultra-high strength concrete by 3-31% [Citation 15, Citation 16].

The primary goal of this study is to examine the influence of CS on both the corrosion resistance of reinforced copper slag concrete composite (CSCC) and the bond strength between the reinforcing steel and CSCC. The corrosion resistance of CSCC was assessed through accelerated corrosion test (ACT), while the bonding characteristics were ...

The effect of ground copper slag (GCS) on the strength and fracture of cement-based materials is studied. Up to 15 percent by mass of ground copper slag was used as a portland cement replacement. The strength and fracture toughness of concrete samples were studied using closed-loop controlled compression and three-point bending fracture tests.

The present work investigates copper slag as a substitute for river sand in high-strength concrete. The concrete mixtures were manufactured with 10%, 30%, 50%, 70%, and of copper slag to evaluate the mechanical and durability properties. The experimental results indicate that replacing copper slag above 50% affects the performance characteristics …

The results presented in this paper indicate that the replacement of natural sand with copper slag improves the abrasion resistance and slake durability of concrete significantly in addition to its strength properties. 80% replacement of natural sand with the copper slag is found to be the most effective as it results in the concrete's highest ...

The addition of CaCO 3 to the cement and copper-tailed slag-based cement materials enhance inter-particle bonding, structural compactness, and reduces the number of pores within the test block, thereby reducing the amount of pore water that can be accommodated. Consequently, the damage caused by the expansion of ice crystals during the …

Finally, utilisation of the copper slag waste in the concrete industry to promote environmental sustainability is discussed. This review demonstrates that processing and repurposing of copper slag waste has benefits of a circular economy such as increasing critical metal supply, lowering the cost of concrete, and reducing environmental harm.

Global copper slag (CS) emissions reached 57.2 million tons in 2021. Despite the increasing reuse of CS, the treatment of CS is still dominated by landfill so far, which not only …

Concrete with Copper slag replaced with fine aggregate. Here, the results of experimental work are presented in Chart and graphical form. Based on the result obtained, the discussions are carried out as under for different tests. 1. FRESH CONCRETE TEST(SLUMP) :- Fresh concrete or plastic concrete is a freshly mixed material

Keywords: Copper Slag, Concrete Abstrak Penggunaan copper slag sebagai bahan pengganti sebagian agregat halus karena copper slag memiliki bentuk dan gradasi yang menyerupai pasir alam. Bentuk fisik copper slag yaitu berbentuk pipih dan runcing (tajam) dan sebagian besar mengandung oksida besi dan silikat serta mempunyai sifat kimia yang stabil. ...

3.2. Workability of the Copper Slag Concrete. Concrete workability refers to its capacity for easy placement, compaction, and finishing without facing issues such as separation or bleeding. Factors such as the water-to-cement ratio, the quantity and nature of the aggregate, and the incorporation of chemical admixtures influence this attribute.

The aggregate type with 37.5% copper slag and 62.5% fly ash showed optimum strength properties and was selected for the production of CSFA aggregate concrete. The strength and durability properties of concrete with a varying replacement ratio of CSFA aggregate from 0 to at normal temperature and at elevated temperatures of 200, 400, and ...

Global copper slag (CS) emissions reached 57.2 million tons in 2021. Despite the increasing reuse of CS, the treatment of CS is still dominated by landfill so far, which not only occupies land resources but also causes damage to the environment. The application of CS to cement-based materials (CBMs) is one of the main approaches to its comprehensive …

Ultra-High Performance Concrete (UHPC) was hindered by the use of non-renewable quartz sand, so there was a need to find a new sustainable material to replace quartz sand. This study investigates the possibility of using copper slag as an aggregate instead of quartz sand to make sustainable UHPC. To ensure the workability and good particle build-up …

The copper slag used in the experiment had a density of 3660 kg/m 3, in contrast to the density of sand, which leads to the increase in concrete density as more copper slag was added (shown in Table 2).The fineness modulus of the copper slag was 1.78, which was finer than sand. The particle size of the copper slag was well distributed within the range of 0.1–1 …

Copper slag (CS) is an industrial byproduct obtained in sterlite industries [4].Copper slag waste was extensively recycled and repurposed in cement and concrete production utilizing cutting-edge techniques, generating a product for a circular economy and environmental benefits.

Generally, the commonly used substitution rate of cement by slag is approximately 50 % [5].However, to further reduce carbon emissions, the dosage of slag can reach up to 80 % which can negatively impact certain physical properties of cement, particularly its mechanical strength [5].The inclusion of nanomaterials, such as nSiO₂, has been explored to counteract …

Leaching studies of copper from copper slag admixed concrete: 10x10x10cm 3 concrete cubes with water to cement ratio of 0.44 were cast using copper slag. After 24 hours, the mortar specimens were demoulded and kept immersed in various aqueous media such as tapwater, rainwater and sea water. Periodically copper leaching is estimated using AAS.
