Comparative Study of Conventional Paver Block with Coir Fibre Filled Waste LowDensity Polyethylene Paver Blocks

Abstract

Plastic waste materials pose great challenge worldwide as they affect both human and marine life, in every environment where waste is indiscriminately disposed of. The use of coir fibre and WLDPE for the production of paver block has been studied. Rockwell hardness, water absorption , and compression tests were conducted on samples developed with cement and WLDPE with 5%,10% and 15% coir fibre-content. This is supported with Phenom Pro Desktop SEM. The convention paver block recorded a hardness valu e of 97.3RHN while the 15% filled WLDPE block had the highest hardness value of 91.3RHN compared to other WLDPE blocks. The water absorption result showed that the 5% filled WLDPE blocks absorbed 2.20%, the cement block had 4.96% water absorption and the 15% filled block recorded absorption of 8.20%%. The WLDPE blocks, however, showed better compression strength than the cement blocks. The 5% filled WLDPE had the highest compression strength of 20.1MPa with the cement block recording a value of 9. 56MPa.Res ults from this study show that WLDPE offers better and cheaper alternative for the production of paver blocks.
