“…Similarly, as the pressing duration increased from 2 to 8 min, the water absorption decreased from 0.415 % to 0.275 %. The observed pattern of increasing and decreasing findings in this study, consistent with previous research reports referenced as [ 40 , 41 , 46 ], suggests a similar trend or phenomenon observed in those studies. The pressing duration, which refers to the duration of the highest-pressure application to minimize relaxation during paver tile production, influences water absorption, as evidenced by the decrease in water absorption with increasing pressing duration [ 28 , 31 ].…”

“…Recycling of waste plastic as replacement of natural aggregates can be a hopeful approach to reduce the number of environmental hazards, social issues and health risks associated with extraction of natural aggregates (Jain et al 2022 ). In past, several research works were conducted on the determination of strength (Sim and Park 2011 ; Gu and Ozbakkaloglu 2016 ) of waste plastic aggregate-based concrete.…”

The study presents the mechanical and durability properties of concrete made up of recycled-waste-polyethylene (PE) and waste-polyethylene-terephthalate (PET)-based aggregate as replacement of natural fine and coarse aggregate, respectively. For this purpose, compressive strength, sorptivity, water permeability, aggressive exposure in acid, base, marine and wastewater, impact resistance, abrasion loss including surface and Cantabro, gas permeability, rapid chloride penetration test (RCPT), elevated temperature and leachability test of microplastic were performed. The experimental works were performed for different volumetric replacement (0–40%) of natural fine and coarse aggregates by PE and PET made aggregate respectively for different curing periods. The experimental results revealed that the sorptivity of PE-based concrete was lowest. Water permeability coefficient signified that with the increase of percentage of PET water permeability increased. In case of aggressive exposure test, the percentage of residual mass and residual strength for all replacement was decreased with the increase in exposure period. Further, impact resistance test result signified that energy absorption increased with the increase of PE and PET percentages. Cantabro and surface abrasion weight loss showed similar trend. Carbonation depth was increased with increasing percentages of PE and PET signified strength decreased with increase of percentages of PE and PET when subjected in CO 2 . RCPT test results demonstrated that with increase of PE and PET percentages chloride ion penetrability was reducing. It is observed that below 100 °C temperature, compressive strength of all mix proportions was not affected with elevated temperature. Moreover, the PET-based concrete showed no presence of microplastic in case of leachability test.

“…In a bid to conserve natural resources and reduce the detrimental effects of construction operations on the environment, recent research has explored recycling plastic wastes in concrete as a potentially environmentally beneficial substitute for natural aggregates [1], [28]. A potentially effective way to reduce the number of environmental dangers, social problems, and health risks linked to the extraction of natural aggregates is to recycle waste plastic in place of natural aggregates [29].…”

Plastic waste is an undeniable source of pollution that threatens the existence of the earth’s flora and fauna. The bulk of plastic wastes generated globally does not go through the proper methods of disposal but is carelessly discarded into the aquatic or terrestrial environment. Current recycling efforts are largely inadequate and disposal in landfills is still fraught with environmental and land use challenges. The proper disposal of plastic waste, as well as mitigating the environmental, social, and health impacts of extracting natural aggregates can be achieved by incorporating plastic waste as aggregates in the construction industry. This paper presents a characterization of aggregates manufactured from polyethylene terephthalate plastic waste using thermal/mechanical methods. Morphological, intrinsic and mechanical characteristics of the produced aggregates were established using standard procedures and equipment. The results of morphological characterization show a dense graded aggregate with fineness modulus of 4.25, flakiness index of 26% and elongation index of 16%. Intrinsic characterization yielded particle density of 1330kg/m3, bulk density of coarse aggregates of 715kg/m3 and water absorption of 0.445%. Mechanical characteristics of aggregates were evaluated, with compressive strength of 50Mpa, Aggregate Crushing Value of 37%, Ten Percent Fines Value of 71KN, Aggregate Impact Value of 24% and Aggregate Abrasion Value of 20%. The characteristics of PET aggregates confirm their suitability for application in structural lightweight concrete and rigid pavement. The produced PET aggregates can be considered in mix design as a total or partial replacement of natural aggregates in concrete.
