Use of Waste Plastics as Building Materials- A New Step in Sustainable Construction Technology

Abstract

The dangerous problem in the contemporary world is plastic trash. This problem represents the biggest danger to civilization. These plastic wastes have a negative impact on the aquatic life, and they also cause the sea water's quality to decline. We look for practical answers to the problem of plastic pollution. Consequently, action is done to create the plastic bricks from waste plastic. It is the most economical option presently being used in the construction industry. It is also advantageous for the environment. In our research, we gathered waste plastic from the neighbourhood municipality, mixed it with the appropriate amount of sand (0.8 kg of plastic and 3.2 kg of sand), and burned it correctly in a pit so that the plastic melted easily. We then poured this mixture into a brick mould and let it sit for a few hours. It is demoulded and kept available for laboratory tests after three to four hours. The water absorption test result and compressive strength result given in Table 2 indicates that the plastic brick is definitely an alternative solution of clay brick and from Table 3 it is also concluded that plastic bricks are economical for use.
