INCORPORATION OF WASTE GLASS, FLY ASH, METAKAOLIN, AND SILICA FUME IN PAVER BLOCK PRODUCTION: LITERATURE SURVEY

This literature survey examines the incorporation of waste glass, fly ash, metakaolin, and silica fume in the production of paver blocks, focusing on their impact on the physical and mechanical properties of the blocks. The study reviews various research efforts aimed at enhancing the performance and sustainability of paver blocks by utilizing these supplementary materials. Waste glass, as a recycled material, has been explored for its potential to improve the aesthetic qualities and durability of paver blocks. Fly ash, a by-product of coal combustion, contributes to increased strength and reduced permeability when used as a partial cement replacement. Metakaolin, a high-reactivity pozzolan, enhances the density and durability of paver blocks, while silica fume, known for its fine particle size, improves the overall mechanical performance and resistance to chemical attacks.
The survey highlights key findings from recent studies, including the improved compressive strength, abrasion resistance, and durability of paver blocks when these materials are incorporated. Additionally, the environmental benefits, such as reduced reliance on virgin materials and decreased waste generation, are discussed. The review also identifies gaps in current research and suggests areas for future investigation to optimize the use of these materials in paver block production.
