Partial Replacement of Cement in Concrete for Strength Enhancement of Ternary blended aerated concrete using Blends GGBS, Fly Ash

AbstractThe present review paper focuses on the partial replacement of Ordinary Portland Cement (OPC) withsupplementary cementitious materials (SCMs), particularly Ground Granulated Blast Furnace Slag(GGBS) and Fly Ash, for developing sustainable and high-performance aerated concrete. Theproduction of conventional cement contributes significantly to energy consumption and carbondioxide emissions. Therefore, incorporating industrial by-products as partial cement replacementsoffers a promising approach to reducing environmental impacts while improving concrete properties.This review examines previous research on the effects of GGBS and Fly Ash on the workability,compressive strength, tensile strength, flexural strength, density, and durability of concrete. It alsohighlights the potential benefits of combining these materials in ternary blended concrete andidentifies research gaps related to optimum replacement percentages and strength development. Theproposed study considers different replacement levels of 5%, 10%, and 15% in M30-grade concrete.The review aims to identify suitable material proportions for achieving improved mechanicalperformance, reduced cement consumption, and environmentally sustainable concrete..
