-------------------------------------------------------------------------***---------------------------------------------------------------------------in India has exacerbated the country's solid waste Abstract-The use of various types of plastic has increased problem. It's general knowledge that discarded plastic in recent years as a result of growing manufacturing and bottles take a long time to decompose naturally (more than other human activities. The majority of plastic garbage is a hundred years). In past few years, recycling of plastic discarded, necessitating a vast landfill space for storage. waste has become one of India's most thinkable issues. In More significantly, plastic's limited biodegradability our country, we now have a range of plastic manufacturing presents a significant danger to environmental protection. factories. They recycle a lot of plastic and put it to good use To reduce the detrimental impact of plastic on the in a variety of ways. Researchers have looked into a environment, many techniques of plastic disposal have been number of materials, including employing waste plastic devised. To limit plastic exposure to the environment, several chips as lightweight aggregate in lightweight concrete types of plastic have lately been mixed into concrete. The construction. Lightweight aggregates can be used instead goal of this study is to examine the properties of concrete. of regular aggregates to reduce the unit weight of concrete. including the use of polymers such as polyethylene In today's literature, there are a variety of lightweight terephthalate (PET) and high density polyethylene (HDPE) concrete uses that use natural or manufactured lightweight to replace coarse aggregate in some circumstances (CA). The particles. Rebeiz et al. (1991), Rossignolo and Agnesini influence of adding waste plastic to concrete's mechanical (2002), Silva et al. (2005), Marzouk et al. (2007), and Choi properties is investigated in this study. According to test et al. (2008) are just a few of the studies that have looked results, 10% PET plastic substituted concrete has a at the usage of recycled Polyethylene Therephtalate (PET) minimum drop in compressive strength of 35%, but splitting as a light aggregate (2008). (2005). PET and other plastic tensile strength has improved by 21% when compared to wastes (PE and PP) were combined in concrete by Koide et control concrete. Furthermore, as compared to control al. (2002), who largely replaced mineral aggregates with concrete, the fresh unit weight of plastic waste-containing PET and other plastic wastes (PE and PP). To investigate concrete was reduced by 4%. the mechanical behaviour of waste PET concrete, Albano et al. (2009) adjusted the water-cement ratio from 0.52 to Key Words— Plastic waste, Plastic chips, Coarse aggregate, 0.6, the PET aggregate concentration (10 and 20% by Slump, Compressive strength, Flexure tensile strength. volume), and particle sizes of 2.5mm and 11.5mm. As the volume percent and particle size of PET aggregate start to 1. INTRODUCTION move up, the concrete's CS, STS, ME and UPV all decreased. Furthermore, there is a improvement in water absorption Plastics have become inextricably linked to our daily lives. ratio. Because the sample cube of concrete were not Its meteoric rise is due to its low density, strength, userthoroughly compacted, honeycomb development occurred, friendly designs, production capabilities, extended life, which had a major impact on the strength values. Frigione light weight, and less cost. Plastics have been used in crime is a fictional character created by Frigione prevention, food preservation and distribution, housing, (2010)attempted to substitute % of the natural sand in communication materials, security systems, and a variety concrete & PET aggregates found from discarded of other applications, including water desalination and unwashed PET bottles (WPET). Various cement and other packaging, vehicle and industrial purposes, and landwater-cement ratios were used to create the specimens. To soil conservation. Plastic is intricately interwoven to our investigate the impact of substituting WPET for fine everyday lives.. Its meteoric rise is due to its low density, aggregate in concrete, rheological characterization on strength, user-friendly designs, production capabilities, fresh concrete and mechanical testing on WPET/concrete extended life, less weight, and less cost. Packing of auto as well as reference concretes containing only natural fine parts and industrial uses, medical tools packing, manmade aggregate were performed at the ages of 28 and 365 days.. implants, and other pharma uses, Plastics are used in a The WPET concretes exhibited comparable workability, variety of applications, including water desalination, slightly lower compressive and splitting tensile strengths, land/soil conservation, flood control, house hold purpose, and somewhat better ductility than the reference concrete, communication systems, security systems, and other according to him. The goal of this study was to explore if applications. The fast growth in the usage of plastic bottles waste PET aggregate could be utilised as a substitute for © 2022, IRJET
