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 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.
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
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.
Mechanical Characteristics of Concrete with Partial Replacement of Sand by Waste PET Bottle Fibers
AI summary Read the abstract
Researchers found that mixing small amounts of shredded plastic water bottles (2-2.5%) into concrete actually made it stronger, offering a clever way to reuse plastic waste instead of sending it to landfills. While this isn't directly about human health, it matters because it could reduce plastic pollution buildup in our environment—one path toward tackling the growing problem of plastic waste that eventually breaks down into microplastics found in our water, food, and even our bodies.
Waste Plastic as Partial Aggregate Replacement in Concrete: A Review of Mechanical, Durability and High-Temperature Performance
AI summary Read the abstract
This review pulls together existing studies on mixing shredded plastic waste into concrete instead of sand or gravel, finding that small amounts (about 5-15%) can actually make concrete stronger and more crack-resistant while helping keep plastic out of landfills and oceans. This matters for human health because reusing plastic waste this way locks it into solid concrete rather than letting it break down outdoors into microplastics that can contaminate water, soil, and eventually our food and bodies, though researchers note more testing is still needed on long-term safety and emissions before this becomes widespread practice.
Influence of plastic waste addition on mechanical properties of cement mortars: An experimental study
AI summary Read the abstract
Researchers found that mixing small amounts of ground-up PVC plastic waste (5-10%) into cement mortar actually made it stronger and lighter, offering a promising way to reuse plastic trash in construction instead of sending it to landfills. This matters for human health indirectly: finding practical uses for plastic waste in solid, bound materials like concrete could help reduce the amount of plastic that breaks down into microplastics in our environment, water, and food supply.
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.
