Engineering Research on Alkali-Activated Fly Ash-Slag | #Sciencefather

Introduction Alkali-Activated Materials (AAMs) represent a new generation of sustainable construction materials that align with global green and low-carbon development goals. These materials are synthesized by activating industrial by-products, such as fly ash and slag, with alkaline solutions. Their preparation involves mixing strong bases or weak base salts to initiate geopolymerization, producing binders with high mechanical and chemical stability. Among their many properties, electrical conductivity has emerged as a promising feature for multifunctional applications. This research focuses on understanding how alkali-activated fly ash-slag (AAFS) systems achieve superior conductivity and the mechanisms governing this behavior. Conductivity influencing factors The electrical conductivity of AAFS pastes is significantly affected by multiple variables, including pore structure, water distribution, and ion concentration. This study investigates the role of fly ash-slag mass ratios, alka...
