Sustainable Paver Block Development Using Silica Fume and Granite Waste

The rapid urbanization and increasing construction activities have led to a high demand for paver blocks, raising concerns about the depletion of natural resources and environmental sustainability. This study explores the development of sustainable paver blocks by incorporating silica fume and granite waste as partial replacements for cement and fine aggregates, respectively. Silica fume, a byproduct of the silicon and ferrosilicon industry, enhances the mechanical properties and durability of concrete, while granite waste, a byproduct of stone processing industries, serves as an eco-friendly alternative to sand. The research investigates the physical and mechanical properties of the developed paver blocks, including compressive strength, water absorption, and durability. Experimental results indicate that the optimized mix design with silica fume and granite waste not only improves strength and performance but also reduces the carbon footprint associated with conventional paver block production. The study concludes that utilizing industrial waste materials in paver block manufacturing presents a viable and sustainable solution for eco-friendly construction practices.
