Effect of waste copper slag as a substitute in cement and concrete
Copper slag is a by-product of the copper ore purification process that is produced at various stages. Copper slag is widely utilized as an abrasive, as well as a construction ingredient in the manufacturing of concrete and paving materials. Despite, the giant quantities of waste copper slag results in landfilling issues.Jabri et al. [ 114] examined the impact of copper slag on high-performance concrete as the replacement of sand ranging from 0 to 100%. There is a slight rise in the HPC density, nearly 5% when mixed with copper slag compared to the control mix. The use of copper slag up to 50% gives maximum compressive strength.A review on various aspects of high performance concrete

Concrete Made with Partially Substitutions of Copper Slag
The lowest FS of 6.16 MPa was achieved when 100 percent CPS was used, and this was achieved by adding 1 percent nano silica to the 100 percent copper slag mix. The FS of concrete improved from 6.16 to 6.49 MPa throughout the testing process . Furthermore, Table 3 displays the summary FS of concrete with different percentages of Many researchers had already found, copper slag possible to use as a material in concrete. In this experimental study copper slag is used in concrete as replacement material of fine aggregate. For this study, M40 grade of concrete is used and the tests are conducted for various replacement of fine aggregate using copper slag as Experimental study on concrete using copper slag as

Concrete compressive strength prediction modeling utilizing
One of the most critical parameters in concrete design is compressive strength. As the compressive strength of concrete is correctly measured, time and cost can be decreased. Concrete strength is relatively resilient to impacts on the environment. The production of concrete compressive strength is greatly influenced by severe weather An Experimental Study on HPC by Partially Replacing Natural Sand with Copper Slag & Cement with Nano Silica. N. Manikandan, V. Rajagopalan, M. Renganathan. Materials Science. 2017; This paper reports the effect of concrete using copper slag as fine aggregate replacement.

Recent trends in ultra-high performance concrete (UHPC):
The resulting concrete is known as ultra-high strength concrete [121], [122], and it is distinguished for its great durability, self-compactability, and high strength. The concept of UHPC was first introduced by Larrard in 1994 [123]. UHPC is a novel type of concrete recently developed for its superior strength and durability (Fig. 6) [124], [125].This research carries out a comparative study to investigate a machine learning solution that employs the Gaussian Process Regression (GPR) for modeling compressive strength of high-performance concrete (HPC). This machine learning approach is utilized to establish the nonlinear functional mapping between the compressive Estimating Compressive Strength of High Performance Concrete

of using copper slag as a replacement of sand on the properties of high performance concrete (HPC). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to 100%. Concrete mixes were evaluated for workability, density, compressive strength, tensile strength, flexuralHence it is interesting to investigate the effect of copper slag as a cement replacement on the strength of HPC. In this study, three-level of water-to-cement ratios (0.3, 0,4, and 0,5) were chosen.
