Partial Replacement of Fine Aggregate by Using Glass Powder

Abstract

The increasing demand for sustainable construction practices has led to exploration of alternative materials in concrete production. One such material is glass powder, which is produced from waste glass and has the potential to partially replace fine aggregate in concrete. This study aims to investigate the effects of partial replacement of fine aggregate by glass powder on the mechanical and durability properties of concrete. The glass powder, which is rich in silica, can enhance the strength of concrete, making it a more sustainable and environment friendly construction material. With growing concerns about the environmental impact of traditional building materials, the use of glass powder in concrete offers a promising solution for improving the sustainability of the construction industry. The research was conducted by preparing concrete specimens with varying percentages (4%, 8%, 12% and 16%) of glass powder as partial replacement for fine aggregate. The specimens were then tested for compressive and tensile strength. The results were compared with those conventional concrete to evaluate the effect of glass powder on the properties of concrete. This research will provide valuable insights into the potential of glass powder as a sustainable alternative to traditional concrete materials. The findings indicate that the use of glass powder as partial replacement of fine aggregate in concrete can improve the mechanical properties of the resulting concrete, particularly in terms of compressive strength and tensile strength. The compressive strength of the concrete increased with increasing day by day and the highest strength we found in 28 days. The study concludes that partial replacement of fine aggregate by glass powder is a sustainable alternative in concrete production that can lead to improved mechanical and durability properties of concrete. This research presents an opportunity for the construction industry to reduce its carbon footprint by utilizing waste glass and promoting sustainable practices in concrete production.
