A review of Investigations on the Utilization of Plastic Waste in Concrete

Civil Engineering

Manufacturing activities, service industries, and municipal solid waste all produce significant amounts of waste materials. Waste disposal is further impacting the public's increased concern about the environment. One of the biggest environmental problems in the world is solid waste management. When land filling becomes more expensive and scarcer, the use of waste utilization as an alternative to disposal is attractive. Waste items can be utilized in concrete as part of a research project. While each of these waste products offers a unique effect on the properties of fresh and hardened concrete, discarded tires, plastic, glass, steel, foundry sand, and coal combustion by-products have all had their own effects on the properties of concrete. Waste items are used in concrete, helping to reduce disposal concerns while at the same time making it economical. If it is found that reuse of bulky waste is the best method for dealing with the disposal problem, it will be regarded as the most environmentally responsible solution. A significant type of garbage is plastic, which can be repurposed in a variety of ways. Nevertheless, a number of attempts have been undertaken to investigate its possible application in concrete/asphalt concrete. Our modern lifestyle now depends on plastic, and worldwide plastic production has grown greatly during the previous half century. As a result, a considerable amount of plastic-related garbage is produced. Concrete made using recycled trash and waste plastic has recently gained the interest of researchers, and several studies have been published documenting the behavior of concrete containing recycled waste and waste plastic. Virgin plastic materials were also evaluated to identify similarities and differences between concrete with recycled plastics and concrete with virgin plastic materials. It is crucial for both the construction and plastic recycling industries that new construction materials be developed that use recovered plastics. This article offers a thorough evaluation of the effects of waste and recycled plastics on waste management strategies, as well as information on current research about recycled plastics and their impact on fresh and hardened concrete qualities.
