Use of Plastic Waste in Concrete : A Comprehensive Review on Strength of Concrete Mixture with Different Material
AI summary Read the abstract
This review paper looks at how recycled plastic waste (like PET bottles) can be mixed into concrete for building construction, finding that the right amount can actually improve certain properties while reducing landfill waste. This matters because it offers a practical way to reuse plastic that would otherwise pollute the environment—though the paper focuses on construction benefits rather than directly studying whether this affects microplastic exposure or human health, so more research would be needed to confirm concrete made this way doesn't shed plastic particles over time.
The rapid increase in plastic waste has become a serious environmental concern due to its non-biodegradable nature and harmful impact on ecosystems. This study explores the utilization of plastic waste as a partial replacement material in concrete production, aiming to address both waste management and sustainable construction challenges. Various forms of plastic, such as polyethylene terephthalate (PET), polypropylene (PP), and polystyrene (PS), are incorporated into concrete either as aggregates, fibers, or fillers. The research examines the effects of plastic addition on the mechanical and durability properties of concrete, including compressive strength, tensile strength, workability, and resistance to environmental degradation. Results indicate that while excessive plastic content may reduce strength, an optimum percentage can enhance properties like ductility, crack resistance, and lightweight characteristics. Furthermore, the use of plastic waste in concrete reduces landfill burden, conserves natural resources, and contributes to eco-friendly construction practices. This study concludes that plastic-modified concrete can be a viable alternative in non-structural and certain structural applications, promoting sustainable development while mitigating environmental pollution.

Use of Plastic Waste in Concrete : A Comprehensive Review on Strength of Concrete Mixture with Different Material

This review paper looks at how recycled plastic waste (like plastic bottles) can be mixed into concrete for building construction, finding that small amounts can actually make concrete stronger and lighter while keeping plastic out of landfills. This matters for human health because reducing plastic waste means less of it breaking down into microplastics that end up in our soil, water, and eventually our bodies — though more research is needed to confirm plastic-infused concrete is safe and durable long-term before it's widely used.
Performance evaluation of PET-modified concrete with PET granules and manufactured sand as fine aggregates
AI summary Read the abstract
Researchers found that mixing shredded plastic bottles into concrete, replacing some sand, actually made it stronger when used at the right amount (2%). This matters because it gives plastic waste a useful second life instead of it sitting in landfills or being burned, which releases toxic fumes harmful to human health.
Synergistic impact of recycled PET microparticles on the mechanical performance of high-strength and conventional concretes
AI summary Read the abstract
This paper isn't about human health directly—it's about turning recycled plastic bottles (PET) into an ingredient for concrete instead of sending them to landfills. Researchers found that replacing more than 5% of the sand in concrete with crushed plastic makes the concrete noticeably weaker, so they recommend keeping plastic content low and reserving this approach for non-load-bearing uses like sidewalks or decorative structures rather than buildings or bridges.
A Step towards Sustainable Concrete with Substitution of Plastic Waste in Concrete: Overview on Mechanical, Durability and Microstructure Analysis

This review evaluates the use of plastic waste as a substitute material in concrete, analyzing its effects on mechanical strength, durability, and microstructure to assess its viability as a sustainable construction approach.
Potential use of PET and PP as partial replacement of sand in structural concrete
AI summary Read the abstract
Researchers tested whether PET and polypropylene plastic waste could partially replace sand in structural concrete, evaluating the physical and mechanical properties of the resulting material. Using post-consumer plastic in construction is one strategy for diverting plastic from the waste stream and preventing it from breaking down into environmental microplastics.
