Review of Geopolymer Concrete Performance utilizing GGBS, Silica Fume, and Fly Ash Integration

This review aims to provide a comprehensive analysis of the performance of geopolymer concrete when incorporating Ground Granulated Blast Furnace Slag (GGBS), Silica Fume, and Fly Ash. Geopolymer concrete is gaining significant attention as a sustainable alternative to traditional Portland cement-based concrete due to its reduced carbon footprint and improved mechanical properties. GGBS, Silica Fume, and Fly Ash are commonly used supplementary cementitious materials that can enhance the geopolymer concrete’s strength, durability, and workability. The review evaluates the influence of GGBS, Silica Fume, and Fly Ash on various aspects of geopolymer concrete, including compressive strength, tensile strength, flexural strength, permeability, chloride ion penetration resistance, and alkali-silica reaction mitigation. The effects of different combinations, proportions, and curing conditions of these materials on the geopolymer concrete’s properties are examined through a critical analysis of experimental studies and relevant literature.
