Many researchers [2,3] studied the effect of copper slag on the use of copper slag in cement clinker production, and the characteristics of Portland cement mortar and concrete rather than cement, raw, and fine gravel.
The reports of Portland Cement Association show that copper slag has been used in full-scale cement manufacturing in different plants. Production of Portland cement includes the grinding of raw materials, the calcinations of them at 1500 °C and the grinding of cement clinker with gypsum.
The compressive strength of Although copper slag is widely used in the sand blasting concrete was determined to be increase by regarding seven- industry and in the manufacture of abrasive tools, the member and split …
The smooth surface and poor water absorption of copper slag can significantly improve the flowability of UHPC mortar. The inherent high density, high …
GGBS is to make "High Performance Concrete" and the usage of Copper slag is to improve the strength and the results indicates that water demand reduced almost 20% by using copper slag compared to other mixtures. 1.2 SCOPE & OBJECTIVES The scope of this project is to make a use of copper slag and GGBS is to replace on concrete to …
A leaching test was performed on concrete containing copper slag to monitor the heavy metals release. The results obtained, revealed that the mechanical strength of UHPC containing QCS-aggregate and SCS-binder were comparable to or even better than for the reference mixture.
As shown in Table 1, copper slag has a high Fe content and has been used as …

Copper slag was used as a partial replacement for fine aggregate and Bacillus subtilis was used as an additive to increase the self-healing properties of concrete. Five concrete mixtures containing varying amounts of copper slag were produced (0%, 25%, 50%, 75%, and ).
The present study encour aged the utilization of industrial waste copper slag as replacement of natural aggregates in concre te. The results indicate that the use of copper slag in concrete increases the …
The heavyweight ultra-high performance concrete (HUHPC) was prepared with barite sand partially replaced by titanium-rich heavy slag sand (THS) at replacement proportion of 0%, 30%, 50%, 70% and in this work. The results show that THS incorporation can effectively improve the mechanical properties and reduce the volume …

Based on the characteristics of coarse aggregates and the mechanical properties of the concrete samples, they found that 40% of copper slag, 40% iron slag, and 25% of recycled concrete aggregate possessed more strength than the conventional concrete mix [ 32 ].
The fatigue life increased up to 15% addition of copper slag and beyond that started decreasing. Fatigue life of copper slag mixes was reported maximum with 15% copper slag and minimum by the mix having 25% copper slag. The fatigue life of the mix containing 15% copper slag improved by 31% as compared to that of control mix.
