slag-infused high strength concrete beam emerged as the most effective material. This study examines the effects of substituting copper slag (CS) for river sand as a fine aggregate in self-compacting concrete using an experimental design (SCC). Eleven different copper slag mix proportions, ranging from 0% (for the control mix proportion) to 100%, are used to make the concrete. The slump test, U-tube, 17-funnel, and Lbox were test procedures used to examine the properties of fresh concrete. Workability, density, longevity, compressive strength, and tensile strength of concrete mixtures are all assessed. The findings demonstrate that using copper slag as a fine aggregate reduces the density increase of highperformance concrete by 3%.
2.2 K. Ganesh Kumar, Sumathi Rajan This study explores the potential use of granulated copper slag from Sterlite Industries as a sand substitute in concrete mixtures. For this project, M25 concrete grade was selected, and the mix design was constructed using the IS method. The material properties for cement, fine aggregate, coarse aggregate, and copper slag were investigated for the aim of mix design. In this work, an attempt is made to ascertain how adding copper slag in place of fine aggregate impacts the material's compressive strength and split tensile strength.
Key Words: High strength concrete, copper slag, replacement, river sand, self-compacting concrete, mix.

1. INTRODUCTION
This study looked at the mechanical properties of high strength concrete that contained copper slag as a fine aggregate and concluded that, while using less than 40% copper slag as a sand substitute can result in concrete with high strength that is comparable to or better than the control mix, using more of it results in noticeably different behaviours. The workability and strength characteristics were assessed by a series of tests on six different mixing proportions at 20% incremental copper slag replacement of sand from 0% to 100%. The results showed that the concrete with less than 40% copper lag replacement had a higher or equivalent strength to the control specimen, and that its workability had even increased significantly.
Waste disposal in the modern era is a difficult problem that has led to enormous dumpsters popping up everywhere. Reusing and recycling waste materials is the best answer to this waste management issue. Another such substance obtained from the blast furnace is copper slag, which is used in the production of copper. In India, 2.5 to 3 tonnes of slag trash are created for every 1017 pounds of metal removed. Concrete is a useful application for this waste. It can significantly lessen the loss of river sand's natural sources. The copper slag is purchased from Sterlite Industries in Tuticorin and substituted for fine aggregates. Compression strength was examined for different percentages of 0%, 20%, 40%, 60%, 80%, and 100%. This outcome yields the highest percentage replacement at which we can succeed.
2.4 Khalifa S. Al-Jabri, Makoto Hisada, Abdullah H. AlSaidy, S.K. Al-Oraimi This study examined the performance characteristics of high strength concrete (HSC) made with copper slag as a fine aggregate at constant workability as well as the effects of superplasticizer. Two sets of concrete mixtures were created using various proportions of copper slag. The first series consisted of six concrete mixtures with varying concentrations of copper slag at constant workability. The water content was altered in each mixture to make it equally workable as the control mixture. Twelve concrete combinations were made in the second series. Except for the
