Ground waste glass as a supplementary cementitious material for concrete: sustainable utilization, material performance and environmental considerations

This review article delves into the role, potential, and peculiarities of ground waste glass (GWG) as both a supplementary cementitious material (SCM) and a filler in concrete. Motivated by the increasing emphasis on sustainable construction practices, the article explores the potential of GWG in enhancing concrete performance while addressing environmental concerns associated with traditional materials. The comprehensive review encompasses the properties of GWG as an SCM, its global availability, its influence on various concrete properties, its compatibility with cementitious systems, optimization techniques, challenges, and practical applications. Key considerations such as particle size distribution, replacement levels, and chemical activation in optimizing recycled GWG incorporation are also highlighted. This comprehensive review underscores the potential of GWG as a sustainable additive in concrete, enhancing both environmental responsibility and structural performance.
