An Experimental Study on Performance of HDPE Plastic in Concrete Boundary Wall
AI summary Read the abstract
Researchers found that mixing recycled plastic waste (HDPE, the type used in milk jugs and detergent bottles) into concrete for boundary walls can actually make it stronger, with the best results coming from adding about 5% plastic by weight. This matters because it offers a practical way to reuse plastic waste instead of sending it to landfills or letting it break down into microplastics that pollute soil and water—turning a pollution problem into a useful building material.
This study examined HDPE (high-density polyethylene) plastic waste as an added material for concrete Boundary wall. The selection of HDPE was based on its increased strength, hardness, and resistance to high temperatures compared with other plastics. It focused on how HDPE plastic can be used as an additive in concrete to increase its tensile strength and compressive strength. 156 specimens were used to identify the effect of adding different percentages and sizes of HDPE lamellar particles to lower, medium, and higher strength concrete for non-structural applications. HDPE 0.5 mm thick lamellar particles were added at 2.5%, 5%, 10%, and 20% by weight of cement. The results showed that the medium concrete class (with compressive strength equal to 10 MPa) had the best response to the addition of HDPE. The 5% HDPE addition represented the optimal mix for all concrete types. In the pursuit of sustainable construction practices, the integration of recycled materials into concrete production emerges as a pivotal strategy. This research delves into the integration of recycled High-Density Polyethylene (HDPE) plastic aggregates into concrete mixes, with the aim of bolstering both the mechanical properties and ecological sustainability of concrete structures. The study meticulously examines the compressive, tensile, and flexural strengths, along with Young's Modulus of Elasticity, of concrete specimens incorporating recycled HDPE plastic aggregates. Notably, a water-to-cement (w/c) ratio of 0.25 was employed in the concrete mix formulation, optimizing the material's performance. The plastic aggregates utilized in this study were meticulously prepared, comprising 50% recycled HDPE plastic and 50% sand, resulting in a balanced 1:1 ratio for the first type, while the second type featured a 1:2 ratio. Through rigorous experimentation and analysis, the findings elucidate the transformative potential of recycled HDPE plastic aggregates in reshaping conventional concrete production paradigms. This research underscores the viability of recycled HDPE plastic aggregates as a sustainable.

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.
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.
Experimental Investigation on the Performance of Masonry Walls Made of Concrete Units with Plastic Waste Aggregates
AI summary Read the abstract
Researchers tested concrete blocks and walls made with recycled plastic waste (granules or flakes) replacing some normal materials. Adding plastic generally lowered strength, but some walls bent and cracked more gradually before failing, suggesting a tradeoff between strength and flexibility when reusing plastic waste in construction.
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.
