“…Even though the copper slag discovered to have coarse grains, the distribution of particle sizes was determined to be outside the bounds of the typical aggregate gradation used in the production of pavement concrete. Therefore, copper slag may be used to make concrete because it has cementation properties similar to the summation of SiO 2 + Al 2 O 3 +Fe 2 O 3 , which exceeds 70% of the class F-fly ash regulations [16][17][18][19][20][21][22].…”

The objective of this research was to assess the performance of pavement-quality concrete having 100% copper slag as fine aggregate in the presence of steel fibre. In this research, the crimped steel fibre of two lengths (30 mm and 50 mm) and different dosages such as 0.5%, 1.0%, 1.5%, and 2.0% by weight of concrete are included in the concrete having 100% copper slag as fine aggregate and compared with the concrete having river sand and copper slag as fine aggregate without fibre. The mechanical characteristics that are being examined include fatigue performance, bond strength, impact strength, flexural strength, stress-strain behaviour, abrasion resistance, and slabs exposed to both static and cyclic loading. According to the experimental findings, pavement concrete that contains 100% copper slag as fine aggregate and 1% crimped steel fibre in both 30 and 50 mm diameters performs better and is more optimal. An inventive way to manage copper slag waste and create durable, stiff pavement construction is with copper slag in concrete road construction. Utilising copper slag in concrete road construction offers a novel approach to waste management and the creation of environmentally friendly concrete road construction.

This experimental research has been conducted to improve the mechanical properties of the problematic expansive soil using copper slag. The copper slag has been utilized to improve the Talab soil in Nainwa for the rst time. These mechanical properties are consistency limits, compaction, and strength properties. The swelling properties show that the collected soil has a high degree of expansive nature and low speci c gravity. Therefore, the copper slag has been added to the soil from 5-30% at a 5% variation by its oven-dry weight. The experimental results reveal that the free swell index of soil has decreased by 69.88% with the addition of 30% copper slag. It has also been observed that the liquid and plastic limits have been decreased. The plastic limit of soil decreases because copper slag takes place in voids. Due to this phenomenon, the maximum dry density of soil has been increased by 14.75% with the addition of 25% copper slag. The California bearing ratio (CBR) value of soil has been increased to 1.13% (soaked condition) and 3.8% (unsoaked condition) by adding 25% copper slag. This research introduces an empirical relationship between unsoaked and soaked CBR with a determination coe cient (R 2 ) of 0.8254. Moreover, it has been observed that the uncon ned compressive strength of soil has increased by 51.68% with the addition of 25% copper slag. Moreover, the value of R 2 for the experimental results obtained in this research is higher than the published experimental results, presenting the experimental study's accuracy and reliability. In addition, the analysis of variance (ANOVA) test accepts the research hypothesis for the present investigation.

Moreover, the value of R2 for the experimental results obtained in this research is higher than the published experimental results, presenting the experimental study's accuracy and reliability.
