Towards greener concrete: A comprehensive review of waste glass powder as a partial fine aggregate substitute

Abstract

Concrete typically emerges as the superior choice in terms of strength, adaptability, longevity, noise reduction, energy efficiency, and it additionally possesses the advantage of being fully recyclable. The excessive consumption of natural resources such as sand in traditional concrete production poses environmental concerns and makes concrete production as a significant contributor to greenhouse gas emissions. By using waste glass powder as a partial substitute for fine aggregate, the study explores the potential to lower the carbon footprint of concrete, to reduce the reliance on virgin materials, minimize waste generation, and promote sustainable practices in the construction sector and finally contributing to climate change mitigation and environmental stewardship. Also, it can offer cost savings, as waste glass is often readily available at low cost, reducing the dependence on expensive virgin materials. This article assesses the workability, durability, compressive, flexural, and tensile strength of concrete when waste glass powder is used as a partial substitute for fine aggregate. Additionally, it provides a comprehensive summary of the current state of knowledge on this topic, evaluating the outcomes of previous studies, methodologies, and limitations. This review paper aids in understanding the progress made in this field and identifying areas that require further investigation. Overall, preparing a review paper on the performance of waste glass powder as a partial substitution of fine aggregate in concrete consolidates existing knowledge, evaluates performance, identifies benefits, challenges, and guides future research.
