The construction industry's growing concern for sustainable practices has led to the exploration of alternative materials to replace traditional components in concrete production. One such promising material is glass powder, a byproduct of the glass industry. This study proposes a Finite Element Method (FEM)-based model to assess the structural and mechanical properties of concrete when incorporating green glass powder (GGP) as a partial replacement for traditional cementitious materials. The research begins by characterizing the physical properties of GGP to understand its potential as a cement substitute. Subsequently, a comprehensive FEM model is developed to simulate the behavior of GGP as a partial replacement of cement in concrete under various loading conditions. The FEM model considers factors such as material heterogeneity, interfacial bonding, and the influence of GGP on the microstructure of the composite material. Through systematic analyses, the study aims to investigate the impact of different proportions of GGP on the compressive strength and tensile strength of concrete. Additionally, the FEM simulations will provide insights into the deformation patterns, stress distribution, and failure mechanisms within this sustainable concrete. The proposed model offers a platform for optimizing the mix design by considering the mechanical performance and sustainability aspects of green glass powder-replaced concrete. Research findings support using GGP in construction for eco-friendly concrete, offering guidelines to reduce environmental impact and promote sustainability in the industry.
