Abstract

Avinash Kumar1, *, Sanjeev Kumar Verma2 Abstract Blended concrete, incorporating supplementary cementitious materials (SCMs), has gained significant attention in the construction industry due to its potential to improve concrete properties and promote sustainability. This review article provides an extensive examination of how two commonly utilized Supplementary Cementitious Materials (SCMs), namely Ground Granulated Blast Furnace Slag (GGBS) and Steel Slag, impact the properties of blended concrete. The review aims to provide an indepth understanding of the performance and sustainable perspectives associated with the incorporation of GGBS and Steel Slag in concrete mixtures. By examining relevant research studies, industry practices, and case studies, this paper explores the impact of these SCMs on various aspects of concrete properties, such as strength, durability, workability, and environmental impact. The paper begins by introducing the significance of blended concrete and the rationale behind incorporating GGBS and Steel Slag as SCMs. It discusses the composition and properties of GGBS and Steel Slag, highlighting their potential benefits as partial replacements for cement in concrete mixtures. The review explores the impact of GGBS and Steel Slag on the mechanical characteristics of blended concrete, encompassing parameters like compressive strength, flexural strength, and tensile strength. Additionally, it investigates how these SCMs affect the durability aspects of concrete, including resistance to chloride penetration, susceptibility to sulfate attack, and the potential for alkali-silica reaction. Furthermore, the review explores the impact of GGBS and Steel Slag on the workability and rheological properties of blended concrete, considering factors such as setting time, flowability, and viscosity. It also evaluates the environmental advantages of incorporating these SCMs, including reduced carbon dioxide emissions, conservation of natural resources, and waste management benefits. Through the synthesis of available research findings, the paper identifies the optimal replacement levels and combinations of GGBS and Steel Slag in blended concrete to achieve desired performance and sustainability objectives. It discusses the challenges and limitations associated with the utilization of these SCMs and highlights potential areas for further research and development
