Abstract
This study aims to evaluate the mechanical properties of rice husk-based geopolymer concrete when incorporating PET plastic waste as a supplementary material. Incorporating PET plastic waste may enhance the sustainability of rice husk-based geopolymer concrete while potentially improving its mechanical properties through innovative mixture designs. The findings from previous studies indicate that the addition of rice husk ash can significantly enhance the Compressive Strength and durability of geopolymer concrete while also addressing environmental concerns related to waste management and resource utilization. This research will contribute to the understanding of how alternative materials can be effectively integrated into geopolymer concrete. The incorporation of PET plastic waste could further optimize the mechanical performance of geopolymer concrete, promoting a circular economy in construction practices. In this research a comparative laboratory experimental study aimed at evaluating the influence of recycled Polyethylene Terephthalate (PET) plastic waste incorporation on the mechanical properties and durability of rice huskbased geopolymer concrete. The study focuses on two different compositions: one with a low PET replacement level and another with a higher PET replacement level. The research investigates Compressive Strength at 7, 28, and 56 days. A detailed laboratory experimental procedure is described that includes the preprocessing of PET waste into fibers or aggregates, mix proportion design, casting, curing, and subsequent testing. The results indicate that controlled incorporation of PET waste can contribute to sustainability without significantly compromising structural integrity. The findings demonstrate improvements in specific concrete performance metrics including Compressive Strength retention, reduced permeability, and enhanced fire resistance when rice husk ash (RHA). The significance of the observed effects was validated statistically, underscoring the potential of such sustainable materials for future construction practices.
