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

Abstract

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