FEASIBILITY STUDY ON GEOPOLYMER CONCRETE PAVER BLOCKS

This study focuses on developing affordable and sustainable paver blocks for pedestrian facilities. It addresses the depletion of natural resources and the environmental impact associated with traditional materials like Portland cement and crushed stone. Geopolymer concrete, using low calcium fly ash as a binder, is combined with recycled asphalt pavement aggregates to create lightweight paver blocks. Experimental tests are conducted to assess their compressive strength, flexural strength, and water absorption properties. Policymakers in India recognize the importance of environmentally friendly construction materials for pedestrian infrastructure. By incorporating recycled asphalt pavement aggregates into the geopolymer matrix, the study offers a sustainable solution that reduces waste and benefits the paving industry. The laboratory-produced paver blocks undergo tests for dimensions, water absorption, compressive strength, and abrasion resistance. The results demonstrate that the inclusion of recycled asphalt pavement aggregates produces high-quality paver blocks suitable for pedestrian facilities. Overall, this research highlights the use of geopolymer concrete and waste materials in constructing affordable and sustainable paver blocks. It offers a practical substitute for conventional materials while boosting waste management and environmental sustainability by using recycled materials and low calcium fly ash as a binder.
