Implementing Waste Tyre Shreds in Paver Blocks

Abstract: Concrete is widely used in construction, but its demand is causing depletion of aggregate deposits. Researchers are exploring ways to replace aggregates with waste materials to make construction sustainable and cost-effective. Waste materials from industries and agriculture, which pose disposal challenges, can contribute to resource conservation and environmental protection while reducing construction costs. In this review focused on using waste tyre shreds in Paver blocks, trials are conducted to determine the mix design parameters. Factors such as compaction capacity, cement grade required, water content, aggregate quality and gradation, additives, handling equipment, curing method, supervision level, workmanship, quality control and compressive strength are considered. Paver blocks made with waste tyre shred may be suitable for temple yards, house yards, walking and cycling tracks, and light traffic roads in rural areas. They are lightweight, increasing waste tyre usage and facilitating easy handling. Combining them with fly ash or exploring other waste materials like coconut shell, bamboo fibre, and plastic can provide additional options for sustainable construction practices.
