Millions of tons of non-biodegradable plastic waste are accumulated in landfill and ocean each year which causes one of the biggest sources of pollution globally. At the same time, the construction developers are under pressure to adopt sustainable materials. The survey will look at the feasibility of using recycled plastic waste material as a partial replacement for fine aggregates in concrete block production. This study uses polyethylene terephthalate (PET) as sand replacement in varying proportions (5%,10%,15%,20 %) for building Concrete blocks after they were tested for their strength. The results show that up to 10% replacing output comparable compressive strength to conventional concrete, but higher replacing degree reduces compressive strength due to poor interfacial soldering and increased void message The survey looked at loser mechanism, denseness variation, and mix behaviour. Microstructural analytic thinking shows that plastic atoms can reduce cleft extension. The potential welfare is offset by decreased coherence and rigidness when plastic message exceeds optimal threshold. The comprehension of recycled plastic helps address environmental concerns and contributes to lightweight building solutions. The determination supports the usage of recycled plastic as a viable constituent for non-loading-heading application and paves the manner for further inquiry into hybrid waste material integrating, long-condition lastingness appraisal and insurance policy evolution for sustainable building practice.
