Utilization of Plastic Waste in Interlocking Paver Blocks for Sustainable Pavement Construction
AI summary Read the abstract
Researchers found a way to turn plastic waste into strong concrete blocks for roads and walkways by mixing shredded plastic pieces with regular concrete ingredients. The plastic-concrete blocks were just as strong as normal concrete blocks, offering a promising solution to reduce the mountains of plastic waste that pollute our environment. This approach could help tackle two major problems at once: getting rid of plastic trash that can break down into harmful microplastics, and reducing the need to mine natural materials for construction.
The rapid growth in plastic consumption and the resulting accumulation of nonbiodegradable waste have created serious environmental and disposal challenges worldwide.Conventional waste management practices such as landfilling and incineration are insufficient and environmentally harmful.At the same time, the construction industry consumes large quantities of natural aggregates and sand, leading to depletion of natural resources.This study investigates the feasibility of utilizing shredded plastic waste as a partial replacement of fine aggregate in interlocking concrete paver blocks for sustainable pavement construction.M50 grade concrete was designed as per IS 10262:2019 with a mix proportion of 1:1.47:3.04 and water-cement ratio of 0.36.Ten percent of natural sand was replaced with shredded plastic flakes (2-6 mm size).The paver blocks were cast, vibrated, demolded after 24 hours, and water cured for 7, 14, and 28 days.Performance evaluation was carried out through compressive strength and water absorption tests in accordance with IS 15658 standards.The experimental results showed an average compressive strength of 46.67 kN at 28 days and water absorption values between 5.27% and 7.53%, which are within

Pemanfaatan Limbah Plastik Sebagai Bahan Subsitusi Agregat Dalam Pembuatan Paving Block
AI summary Read the abstract
Researchers found that mixing recycled plastic waste (about 15% by weight) into paving blocks—the tiles used for sidewalks and driveways—actually made them stronger than blocks made without plastic, while higher amounts weakened them. This matters because it offers a practical way to reuse plastic waste in construction instead of letting it pile up in landfills or break down into microplastics that pollute soil, water, and eventually enter our food and bodies.

Mechanical Properties of Sustainable Paving Blocks Using Fly Ash and Polypropylene Plastic Waste
AI summary Read the abstract
Researchers found a way to turn plastic waste and fly ash (a coal-burning byproduct) into sturdy paving blocks for sidewalks and parks, without using any cement or water. This matters because it repurposes two hard-to-dispose-of waste materials into something useful, though it's worth noting the process melts plastic at high heat, which is different from letting it break down outdoors where it could shed microplastics into soil and water. While this particular study focused on strength and durability rather than health impacts, using waste plastic in solid, bound construction materials is generally seen as a safer disposal path than letting it degrade in landfills or oce
