Experimental Investigation on Strength Characteristics of Concrete Cubes Using Waste Plastic
AI summary Read the abstract
Researchers investigated the use of municipal plastic waste — primarily polyethylene — as a partial substitute material in concrete production, examining how incorporation of waste plastic affects the compressive strength characteristics of concrete cubes.
This report outlines the utilization of municipal plastic waste (MPW) in construction industries. Plastic is a non-biodegradable substance which takes thousands of years to decompose that creates land as well as water pollution to the environment. The quantity of plastic waste in Municipal Solid Waste (MSW) is expanding rapidly. It is estimated that the rate of usage is double for every 10 years. The Plastic usage is large in consumption and one of the largest plastic wastes is polyethylene (PE). The utilization of earth-based clay material resulted in resource depletion and environmental degradation.

Experimental Investigation on the Mechanical Properties of Concrete with Partial Replacement of Fine Aggregate by Plastic Waste
AI summary Read the abstract
Researchers partially replaced fine aggregate in concrete mixtures with processed PET and other waste plastic particles and found an optimal replacement level that preserved acceptable compressive and tensile strength while reducing density, beyond which plastic-to-cement bonding degraded mechanical performance, suggesting a viable route for incorporating plastic waste into lightweight non-structural construction.
Utilization of Recycled Plastic Waste as Partial Substitute of Fine Aggregate in Eco-Friendly Concrete
AI summary Read the abstract
Researchers tested recycled plastic waste as a replacement for fine aggregate (sand) in concrete, mixing it in at 0%, 10%, 20%, and 30%. Concrete with 10% plastic waste had the highest compressive strength, while plain concrete (0%) had the lowest, and strength declined slightly at 20% and 30%.
Experimental investigation on mechanical and durability properties of M30 concrete with HDPE plastic waste as partial coarse aggregate replacement
AI summary Read the abstract
Researchers tested concrete made by replacing part of the stone material (coarse aggregate) with shredded plastic waste from HDPE bottles and containers, at levels from 10% to 50%. Lab tests measured strength and durability, finding that replacing 10% of the aggregate with plastic waste worked best without weakening the concrete too much.

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.
Valorization of Waste Polyethylene Terephthalate as a Partial Fine Aggregate Replacement in Concrete: An Experimental Assessment of Fresh and Hardened Properties
AI summary Read the abstract
Researchers tested using crushed waste plastic bottles (PET) in place of some sand in concrete. As more plastic was added, the concrete became less workable, lighter, and weaker, but mixes with up to 4% plastic still met standards for lightweight, non-structural building uses.
