Eco-Concrete, Nano-Calcium Carbonate (Nano-Caco₃), Bio-Sourced Nanoparticles, Hashin–Shtrikman Model, Free Vibration Analysis, Raft FoundationAbstract
Natural waste products—such as eggshells, animal bones, and marine deposits—serve as sustainable sources for nano-calcium carbonate (CaCO₃) extraction. Valorizing these nanoparticles for concrete reinforcement is crucial for developing durable, high-performance infrastructure. This study adopts a two-fold approach: first, the Hashin–Shtrikman model is utilized to predict the nanomechanical properties of bio-reinforced eco-concrete; second, the free vibration response of a raft foundation is analyzed using FSDT and HSDT frameworks. Findings reveal that nano-CaCO3 incorporation not only optimizes nanomechanical characteristics but also significantly improves structural stiffness and vibrational stability.
