Experimental investigation on compressive strength addition of leftover building debris to paver blocks using coir fibre

Abstract

India is a country under development. Similar to India, other emerging nations also benefit from cost-effective construction methods and affordable building materials for their national development. The building industry generates close to 12 to 14 million tonnes of waste annually, of which roughly 7 to 8 million tonnes are brick and concrete debris. Waste construction material can play a significant role when added to paver blocks. When employed in paver blocks, the waste recycled construction material is cost-effective and long-lasting because of some of its unique features that are applicable to conventional construction materials. After being crushed using a laboratory jaw crusher, this concrete debris can be substituted in two steps for coarse aggregates. In accordance with Indian Standard standards for paver blocks, as a full 100% replacement and a 40% partial replacement. This garbage is either discarded or diverted toward a landfill. The idea of adding concrete scraps to the concrete used to make the interlocking paver blocks with coir fibre is depicted in this study. In comparison to 0.1% and 0.5% coir fibre, the average compressive strength of paving blocks with 0.3% coir fibre produces the best results. Compressive strength, workability, bulk density, specific gravity, flexural strength, splitting tensile strength, and water absorption tests were analysed in order to build paver blocks with coir fire in various percentages by adding leftover construction materials.
