Performance Enhancement of Low-Carbon Cementitious Systems through Supplementary Materials: A Comprehensive Study on Flow Behavior and Strength Properties

In this book chapter, we investigate the influence of supplementary materials on the flow behavior and strength properties of binary cementitious systems, focusing on silica fume, fly ash, metakaolin, and glass cullet powder. Our study aims to provide practical insights into the development of low-carbon concrete mixtures by exploring the unique characteristics of each material. We assess the effects of these supplementary materials on workability, heat of hydration, pore characteristics, and compressive strength, aiming to bridge knowledge gaps in binary cement compositions. The results indicate that silica fume and metakaolin reduce workability, while fly ash and glass cullet powder enhance it. Notably, introducing 5% glass cullet powder leads to improved rheological properties and a 10% reduction in heat of hydration. The study recommends further exploration of optimal ternary mixtures to enhance concrete properties.
