  • Abstract:
  • The processing and recycling of plastic waste have gained significant momentum due to its value as a resource for various industries, along with the hazardous nature and low recycling rates of plastic materials. Addressing the environmental and ecological issues associated with electronic plastic waste disposal presents a partial solution. Utilizing plastic waste in construction materials offers benefits such as cost reduction, enhanced structural strength, and improved road infrastructure. This paper studies the use of waste plastics and foundry sand as partial replacement of fine aggregate and the use of fly ash as partial replacement of cement in M30 concrete. Concrete mix with 0% waste material is the control mix and water cement ratio adopted is 0.45 in accordance with the Indian Standards specification IS-10262:2019. A design mix proportions of 1: 1.4: 2.6 was investigated for the research. The percentages of replacements of foundry sand is 15% and 20%, HDPE plastic is 4%, 6% and 8% by weight of fine aggregate and fly ash is 20% and 30% by weight of cement. Tests were performed for compressive strength and flexural strength of concrete for all replacement levels of fine aggregate and cement. The results indicate that there is an increase in compressive strength and flexural strength up to 15% replacement with foundry sand, 6% replacement with waste HDPE plastic and 20% replacement with fly ash.
