Utilization of Waste Plastic in Concrete Towards Sustainable Development: A Review
In the present decade, one of the environmental issues in most regions of world is the existence of large number of bottles made from poly-ethylene terephthalate (PET) and huge quantities of plastic wastes deposited in domestic wastes and landfills. These plastic wastes are adversely effecting the environment and is a topic of serious concern for various concerned authorities. In spite of all efforts made to limit the use of plastic based products, their utility is increasing day by day and thus the amount of plastic waste generated is also increasing day by day. Various attempts were made through experimentation to check the feasibility of plastic waste to be use partially in concrete with respect to various properties of strength, workability, durability and ductility of concrete. This paper is aiming to give a over view of various studies conducted on utility of waste plastic material used in the concrete. Highlights: Use of plastic waste in concrete in different forms is discussed. Effect of plastic waste on different properties of concrete is illustrated. Use of plastic waste exceptionally helpful to produce green sustainable concrete. Harmful effects of plastic waste are mentioned.

The growing environmental concerns and proper disposal of construction and demolition waste is a challenge for construction industry. Now a days in our country Solid waste management is one of the major environmental concerns. A substantial growth in the consumption of plastic is observed all over the world in recent years. The use of demolition waste as a resource for recycling or recovery is gaining grounds in many countries. The proper selection and processing of demolition waste can be helpful in producing concrete. In construction industries, concrete masonry units are used commonly. The use of plastic bottles in construction materials has been around for the past twenty years, but with little focus on using threaded plastic bottles in the materials. This work aimed to justify use of threaded plastic bottles and fly ash in concrete. It also aims to investigate the strength of concrete when plastic bottles are used. Plastic bottles are increasingly becoming a menace to the environment due to the chemicals used in the manufacture, improper use and disposal. Waste plastic bottles are major cause of solid waste disposal. This is an environmental issue as waste plastic bottles are difficult to biodegrade and involves processes either to recycle or reuse. As noted by Plastics Industry (2011) reusing plastic bottles may seem safe , but a chemical found in reusable plastic bottles, known as Bisphenol. A (BPA), is suspected of posing a health risk to human beings. Hence, the safest way of disposing plastic bottles is to recycle them, particularly they can be used in the construction . The use of plastic is increasing day by day, although steps were taken to reduce its consumption. This creates substantial garbage every day which is much unhealthy. Plastic bottles are difficult to reuse, recycle and non-biodegrade and hence creates an environment issue. A healthy and sustainable reuse of plastics offers a host of advantages. The suitability of recycled plastics as coarse aggregate in concrete and its advantages are discussed here. Due to ever increasing plastic pollution and construction waste pollution, it has become important to find a way for reducing such waste as it is hazardous to the environment . Plastic bottle is considered as a urban junk with sustainability characteristic which can be used as a material instead of some conventional material such as brick in building in construction. This paper intends to investigate the application of plastic bottles as one of the urban wastage in construction and that how it can lead to sustainable development. M25 design mix casted in which threaded plastic bottles filled with concrete made of using fly ash ,coarse aggregates with plasticizer . Plastic bottles are cut into threaded form. In due course of time, threaded plastic bottles evenly placing in layers into concrete cubes as micro level reinforcement. Later on its compressive strength , split tensile strength , flexural strength are tested . To overcome the above problems of over exploitation of natural resources and environmental issue due to the use of non bio-degradable plastic bottles, attempt has been made to use threaded plastic bottles in concrete. Use of threaded plastic bottles will reduce environmental waste. Hence it also proves to be cost effective. KEYWORD: , Coarse aggregates, Ordinary Portland Cement (53 Grade).
Experimental Investigation on Bricks using Waste Plastic Materials
International Journal for Scientific Research & Development, 2020
The rapid increase in plastic and demolition wastes technology through municipal and commercial industries becomes large issue to advanced and growing countries. The replacement of conventional construction materials with reused materials is a feasible arrangement which mitigates landfilling concerns and decreases the requirement for virgin quarry materials. In these studies, an assessment of Polyethylene terephthalate (PET) plastic waste and its blends, with demolition waste dust had been undertaken. The waste PET bottle is first shredded and soften in the container after which the demolition waste dust is different proportions. The experiments had been accomplished are compressive strength, water absorption and dimension tolerance check. The proportion of waste PET bottles is to be used are 20%, 30%, 40%, 50% by weight. The 30% waste PET bottles+ 70% demolition waste dust have higher compressive strength from the different mix samples. Water absorption is decreases with increases the percentage of PET bottle content in demolition waste dust.

PET (polyethylene terephthalate) waste is a plastic bottle waste that difficult to recycle in large scale, so it was causing environmental pollution. In this research, PET waste used as a main material of bricks by using the mix design method. The mix design method used includes cutting of PET waste, melting of PET waste, mixing with other materials, and molding the materials. This research used four variations of PET waste added by cement and sand to find the ideal composition that mentioned by SNI (Indonesia National Standard). The ideal composition of brick is solid plastic: cement: sand volume ratio is 66:22:12. The result of this research showed that brick quality is ideal, which was characterized by FT-IR and SEM. This composition has 0% of water absorbency, the compressive strength is 75 Kg/cm2, water absorbency of SNI brick is under 20%, and the compressive strength is between 60-100 Kg/cm2.
HARDENED PROPERTIES OF POLYETHYLENE TEREPHTHALATE BASED CONCRETE
Disposing of waste plastic materials has always been point of concern. As PET bottles are of non-biodegradable character, their decomposition is main concern regarding environmental perception. Recycling or reusing is only solution to their decomposition problem. This study deals with the experimental programme on mechanical properties of recycled polyethylene terephthalate based concrete. A Portland fly ash cement based concrete with a 0.43 water/cement ratio is used to cast cured and tested a cylindrical and cubic specimens for 7 days and 28 days strength. PET waste shredded to flakes and added with 0% to 5% with the increment of 1%, with 0% as reference concrete. Comparing with reference concrete observed an increase in compressive and tensile strength. The optimum dosage was 2% for compressive strength and 1% in split tensile strength.
M30 concrete grade was produced using ACI mix design proportioning method in the ratio 1:1.5:2.6 (cement: sand: coarse aggregate) and a water-cement ratio (W/C) of 0.40. WPET and WLDPE were utilized in the production of plast-crete, by percentage replacement by volume of 10%, 20%, 30%, 40%, and 50% of sand with waste plastic. The following samples were produced 110 cubes of 100mm×100mm×100mm for compressive tests, 110 cylinders of 100mm×200mm for split tensile tests, 110 prisms of 100mm×100mm×500mm for flexural tests and discs of 100mm×50mm are used for water absorption tests. The influence of introducing waste PET and LDPE on the compression, tensile, flexural and absorption on the plast-crete, was investigated and compared with that of the convectional concrete (CC). The WPET filled concrete (CP) at 10% replacement, showed a slight decrease of 7%, 8.52% and 8.12% for compressive, split tensile and flexural strength respectively for a period of 28 day cure period compared to that of the CC. In addition, the CP at 10% replacement, showed a slight increase in the water absorption of 4.48% for 28 day cure period compared to that of the CC. The WLDPE filled concrete (CL) at 10% replacement, showed a slight decrease of 10.65%, 10.16%, and 12.52% for compressive, split tensile and flexural strength, respectively, for a period of 28 day cure period compared to that of the CC. However, the CL at 10% replacement showed a slight increase in the water absorption of 9.70% for 28 day cure period compared to that of the CC. Overall the compressive, tensile and flexural strength of the CP was slightly higher than that of the CL. Despite the slight decrease in the compressive, tensile and flexural strength of CP and CL, both concrete mixes showed good workability, and compressive strength of between 20 to 40N/mm 2 which is still very good for the production of fancy blocks for pedestrian walk ways, slabs, partition walls, fences, low-cost housing and light traffic structures, and this was achieved when 5 to 50% WPET and 5 to 40% WLDPE were utilized. In conclusion, CP and CL offer high potential in cost reduction, good cost desirability factors in strength and can be effectively utilized as a tool for disposing our waste plastics and in the process achieve a cleaner environment, create a better and more effective waste management system, create jobs, and help to expand the waste to wealth initiative proposed by the Federal Government of Nigeria.
Utilization of Plastic Bottle Waste in Concrete
Now a day are facing environment protection problems. Many things which are invented for our luxurious life are responsible for polluting environment due to improper waste management technique. One of them is a plastic which has to be disposed or recycled properly to maintain the beauty of our nature. On the other hand, urbanization growth will increase rubbish especially non-renewable ones. Eco friendly architectural principles are being incorporated into more buildings every day in the world but they are still out of reach of many people due to lack of knowledge and awareness. In this study is to explore the possibility of recycling a plastic bottles waste material. To address this issue the fibers from used plastics were added in various percentages in the M25 grade concrete. An experimental work has been carried out on the specimen's cubes which were casted in the laboratory and their behavior under the test was observed. The plastic fibers were added from 0.0% to 3.0%. The compressive strengths of concrete were determined after 28 days of curing period and compared with control concrete. Experiments done shows increase in compressive strength by 12%. Plastic bottle fibre additive can be adopted. The plastic bottle fibre reduces the quantity of industry fibers used in concrete and also plastic bottle fibre is proved to be more economical.
