This review paper investigates the use of steel slag as a partial replacement for fine aggregate in high-strength concrete, a promising approach to enhancing concrete properties and promoting sustainable construction practices. Steel slag, a by-product of the steel manufacturing process, offers high density, hardness, and angularity, which can improve the mechanical properties of concrete. The study systematically reviews the influence of varying steel slag content on key parameters such as compressive strength, tensile strength, and flexural strength, comparing it with conventional fine aggregates. The research indicates that incorporating steel slag can significantly enhance the compressive strength of high-strength concrete due to its superior binding properties and improved particle packing density. Moreover, the angular nature of steel slag particles contributes to better interlocking within the concrete matrix, thereby increasing tensile and flexural strengths. The review also examines the durability aspects of steel slag concrete, including its resistance to chemical attack, chloride penetration etc., highlighting its suitability for harsh environmental conditions. this paper provides a comprehensive overview of the potential and challenges of using steel slag as a partial replacement for fine aggregate, emphasizing its technical, environmental, and economic advantages. It calls for further research to standardize the use of steel slag in concrete and to explore innovative processing techniques to mitigate any adverse effects on concrete properties. This study contributes to the growing body of knowledge on sustainable materials in construction and supports the development of more eco-friendly and durable concrete solutions.
