5 th International Structural Integrity Conference & Exhibition (SICE 2024) Sustainable concrete incorporating waste glass powder and recycled aggregate: performance evaluation Sphurty Raman * , Raman Nateriya, Yash Rathore a Department of Civil Engineering, Maulana Azad National Institute of Technology, Bhopal, Madhya Pradesh, 462003, India Abstract The overexploitation of natural resources for concrete production has raised significant environmental concerns. Utilising waste glass powder (WGP) and recycled concrete aggregate (RCA) as replacements for natural fine and coarse aggregates, respectively, offers a promising sustainable solution. This study investigates the performance of concrete incorporating various proportions of WGP (up to 40%) and RCA (up to 60%) using regression analysis. The influence of these eco-friendly aggregates on key properties such as compressive strength, split tensile strength, flexural strength, workability, and water absorption is examined at different curing ages. The developed regression models establish the relationships between replacement levels and concrete properties, guiding the optimal incorporation of WGP and RCA in concrete mixtures. The findings demonstrate that concrete with up to 25% WGP and 40% RCA exhibits comparable or enhanced mechanical properties and durability compared to conventional concrete. This research highlights the potential of WGP and RCA in producing sustainable concrete, addressing waste management, and resource conservation challenges without compromising technical performance. © 2025 The Authors.

1. Introduction Concrete, the most widely used construction material globally, faces significant environmental challenges due to its resource-intensive production and high carbon dioxide emissions (Htet et al., 2022; Kim et al., 2018). The concrete industry consumes 60-75% of natural aggregates by volume, contributing to resource depletion and carbon emissions from mining activities (Htet et al., 2022; Zhou and Chen, 2017). With increasing urbanization and infrastructure development, there is an urgent need for sustainable alternatives that can reduce the environmental impact while maintaining performance (Paul et al., 2022; Arivalagan and Sethuraman, 2021). Researchers have explored various waste materials as potential replacements for natural aggregates in concrete
