This research project aims to investigate the feasibility and efficiency of using steel slag as a partial replacement for ordinary Portland cement in concrete. The study will focus on evaluating the mechanical properties of concrete with varying proportions of steel slag, including compressive strength and split tensile strength. Additionally, the durability parameters of the concrete will be examined to ensure the long-term performance of the material.
modern societies, but meeting all requirements poses challenges. Concrete has been a reliable construction material for decades, and engineers seek to enhance its performance using modern admixtures and waste materials. Incorporating waste materials in concrete consumption and improving its properties are benefits. This research explores the use of Steel Slag as a partial replacement for cement in varying proportions (0%, 5%, 10%, and 15%). The study focuses on compressive strength and other parameters such as workability, water-to-cement ratio, setting time, and surface hardness, which impact concrete performance. Results indicate that Industrial steel slag is a promising cement substitute, outperforming reference concrete.
The outcomes of this research hold significant implications for sustainable construction practices. Finding an optimal combination of cement and steel slag can lead to reduced CO2 emissions and a more cost-effective concrete mix. Moreover, the study contributes to the circular economy concept by promoting the reuse of industrial byproducts, thereby moving towards a greener and more environmentally friendly construction industry.
Implementing a circular economy in construction necessitates studying waste utilization as material replacements. Substituting cement with slag reduces cement consumption, lowers CO2 emissions, and addresses waste management concerns. Embracing such sustainable practices will lead to a more resilient and eco-friendly infrastructure.
By addressing these research objectives, this study seeks to pave the way for a more sustainable and resilient approach to concrete production, aligning with the global efforts to mitigate climate change and foster environmentally conscious construction practices.

This research holds significant importance for several reasons:
1.INTRODUCTION
1. The potential discovery of a new concrete with improved strength and durability.
Concrete is a widely used construction material due to its durability, versatility, and cost-effectiveness. However, the production of ordinary Portland cement (OPC), a key component of concrete, is associated with significant carbon dioxide (CO2) emissions, contributing to environmental concerns. As a result, there is a growing interest in exploring alternative materials that can partially replace OPC in concrete mixtures, reducing its environmental impact.
2. Gaining valuable insights into the behavior of concrete through various tests. 3. Contributing to substantial research on the resistance and viability of replacement materials. 1.2 OBJECTIVES
One such alternative material is steel slag, a byproduct of the steel manufacturing process. Steel slag possesses cementitious properties and has the potential to enhance the performance of concrete while offering a sustainable solution for waste management. By incorporating steel slag in concrete, not only can the demand for OPC be reduced, but the overall carbon footprint of the construction industry can also be minimized.
