Abstract: The global manufacturing of traditional Portland cement generates massive carbon dioxide emissions that accelerate climate change. This study investigates a sustainable alternative by substituting thirty percent of cement binder with calcined clay and rice husk ash. Comprehensive laboratory testing will evaluate the resulting compressive, flexural, and tensile strength characteristics over a ninety-day curing period. Additionally, specialized durability experiments will measure the material’s long-term resistance to aggressive chloride penetration and acid attacks. The microstructural density of the hydration products will be analyzed using scanning electron microscopy imaging. This research aims to deliver a viable, low-carbon concrete formula for green commercial building applications.
