Strength of Sand concrete Blocks Production Using Waste Plastic (Pet)
AI summary Read the abstract
This paper isn't really about human health directly, it's about testing whether recycled plastic waste can replace some of the sand used to make concrete blocks for building homes. Researchers found that replacing just 5% of the sand with shredded plastic made blocks strong enough for construction, offering a way to build more affordable housing while reducing plastic pollution and excessive sand mining. However, higher amounts of plastic weakened the blocks too much to meet safety standards, so more research is needed before this becomes widely used.
Sandcrete block is the most popular building material in construction industry. With the high cost of building it is becoming difficult for an average man to achieve an affordable housing. Again the dredging of sand for block production, the incessant dumping of plastics wastes in the environment is of great concern. This study aims to replace sand in sandcrete blocks production and investigate the suitability of using such blocks for building designs. This research discussed the material used, the methodology of production. The plastic was washed, dried, melted and shredded. Sieve analysis was performed on the sand and plastic samples, water absorption and compressive strength tests were conducted on the blocks at 28 days of curing. The tests revealed that the 5%replacement gave a good result of 3.27 N/mm2 which is suitable for block making. The other compressive strength results were below the standard recommended by Nigerian Industrial Standard. For the production of cost effective and performing sandcrete blocks, plastic wastes will serve since they are cheaply available, sustainable and recyclable. This will also help to reduce environmental pollution level. To improve the quality of sandcrete blocks, suitable selection of constituent materials.

Strength of Sand concrete Blocks Production Using Waste Plastic (Pet)
AI summary Read the abstract
Researchers found that mixing a small amount (5%) of shredded plastic waste into sand-based building blocks can produce strong, usable construction material while cutting costs and reducing plastic pollution. This matters because it offers a practical way to reuse plastic trash instead of it ending up in landfills, oceans, or breaking down into microplastics that can enter our water, food, and bodies. However, adding too much plastic weakened the blocks, so getting the ratio right is key to making this approach safe and effective for real-world building.
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.
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.
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.
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.
