“…Most studies suggest that when CS replaces fine aggregate or coarse aggregate, a certain amount of CS can enhance the workability of CBMs, but excessive CS can cause bleeding [ 27 , 28 , 30 ]. As shown in Figure 9 , slump of fresh CBMs significantly increased with the increase in CS content.…”

“…Larger particle size CS can replace the fine aggregate and coarse aggregate in some CBMs to address the resource crisis of natural sand and stone shortage. When CS used as fine aggregate is added to CBMs, it delays the setting time of CBMs [ 22 , 23 , 24 ], it enhances the workability of CBMs [ 25 , 26 , 27 , 28 , 29 , 30 ], it improves the mechanical properties of CBMs [ 30 , 31 , 32 , 33 , 34 , 35 , 36 ], and it enhances the durability of CBMs [ 19 , 25 , 26 , 37 , 38 ].…”

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 utilization and has important economic and social implications. This article reviews the physicochemical properties, activity excitation, and heavy metal leaching properties of CS and summarizes the effect of CS on the working properties, mechanical properties, and durability of CBMs. At the end of the article, the existing problems in the research are analyzed, and the development trend is proposed, which provides technical guidance and reference for further research and application of CS in CBMs in the future.

“…40 A distribution was carried out based on particle density on fine aggregates and was found that the maximum size of copper slag has least impact on the amount of bleeding. 41 A study on mechanical properties of reinforced concrete with copper slag under dynamic compression revealed the effects that dynamic strength (compression) of reinforced concrete with slag enhances up to 20% copper slag substitution as fine aggregates in comparison to reference concrete. 42 Figure 5 gives a microscopic view of the concrete at 50 times magnification with different proportions of copper slag.…”

The challenge before the construction industry is to meet the demand of the efficient and economically viable construction materials posed by the huge infrastructural needs. Many nations are observing an expeditious growth in the field of construction necessitating the utilization of natural reserves for the expansion of infrastructure. This expansion is giving a warning to available reserves of nature. The natural ingredients, fine aggregates and coarse aggregate constitute more than 70% volume of the concrete. The availability of these resources is decreasing at a very high pace. In fact due to the severe problem with the availability of natural sand, the construction industry is faced with the pressing need to consider available options to lessen the reliance on natural aggregates. Copper slag being a waste material, can be used as an option for fine aggregates. The substitution of fine aggregate from nature with waste materials from industries such as copper slag offers economic and technical dominance, which are of pronounced significance in the present scenario. This study is, based on the critical review of the development of High Performance Concrete (HPC) by replacing fine aggregate with copper slag by observing various other researches and reviews. The key intent of this paper is to closely look at the copper slag utility as an unconventional material to be used as a substitute of fine aggregate and its effect on mechanical and durability parameters of HPC.
