Repurposing Single-Use Plastic Waste as Artificial Aggregates Partially Replacing the Natural Fine Aggregate in Concrete — A Review
AI summary Read the abstract
This review examines how single-use plastic waste can be repurposed as aggregate material in concrete mixtures, replacing natural sand. Analyzing 135 studies, it finds that recycled plastic aggregates can affect concrete mechanical properties while diverting plastic waste from landfills and oceans.
There is a growing increase in the global consumption of plastic in recent times. Reutilization of plastic by recycling is a highly effective solution to manage the increasing plastic waste (PW). Besides, reuse of plastic also helps in improving environmental sustainability. In this context, there is a great demand for the recycled plastics in various applications. This review paper presents an empirical evaluation on the application of single use plastic waste as an artificial aggregate as a replacement to the natural fine aggregate (FA) in concrete mixtures. This review also discusses the influence of mechanical properties on the cementitious composites consisting of plastic waste aggregate (PWA). This paper reviews an overall 135 research papers and illustrates different types of plastics and their application in improving the concrete properties. The review also provides an overview of the works proposed by different researchers and highlights their contribution. In addition, this paper also identifies the research gaps and highlights some of the prominent observations.

Utilization of plastic waste as replacement of natural aggregates in sustainable concrete: effects on mechanical and durability properties
AI summary Read the abstract
Researchers tested concrete made with recycled polyethylene and PET plastic aggregates substituted for natural sand and gravel, finding that while plastic additions reduced compressive strength and increased water permeability, they improved impact resistance and chloride resistance, with PET concrete showing no microplastic leaching.
Waste Plastic as Partial Aggregate Replacement in Concrete: A Review of Mechanical, Durability and High-Temperature Performance
AI summary Read the abstract
This review of existing studies finds that mixing small amounts of waste plastic (about 5-15%) into concrete can help solve two problems at once: reducing plastic waste in landfills and cutting demand for mined sand and gravel. While this doesn't directly address microplastic exposure in food or water, it offers a way to lock plastic waste into durable building material instead of letting it break down in the environment.
