  • Abstract:
  • This study emphasizes the need for green construction practices in developing countries to combat global warming. To mitigate global warming, it's essential to ensure that construction methods are sustainable, durable, and environmentally friendly. Industrialists must focus on producing and using materials that are harmless, long-lasting, affordable, easy to assemble, and suitable for the environment. Researchers should explore using waste materials such as plastic waste and fly ash as substitutes for coarse aggregates and PPC cement in concrete mixes. This experimental study presents significant results, demonstrating the potential of using plastic waste and fly ash in optimal amounts as partial replacements for aggregate and cement in concrete for rigid pavements. The results are compared with standard concrete to assess properties such as compressive strength, split tensile strength, and flexural strength. The findings from the experiments reveal the effective use of plastic waste and fly ash. When fly ash (15%) is used to replace cement and plastic waste (5%) replaces coarse aggregate with a water-cement ratio of 0.55, there is a 33% increase in compressive strength, a 15% increase in tensile strength, and a 25% increase in flexural strength after 28 days of testing. At a water-cement ratio of 0.60, the improvements are even more pronounced, with a 31.6% increase in compressive strength, a 50% increase in tensile strength, and a 10% increase in flexural strength after 28 days of curing in the lab.
