Investigating the Application of Plastic Bottle as a Sustainable Material in Building Construction

One of the main disadvantages in constructing houses is high cost of the building materials. Building materials are the primary requirement for constructing the house in places where people are below poverty line and is becoming one of the most significant problems of peoples. On the other hand, urbanization growth will increase rubbish wastes 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 poor people due to lack of knowledge and awareness. In this project we implemented strategies and systems based on Eco-friendly environment that could still be built at very low costs, with waste materials that is plastic bottle, providing adequate thermal comfort while being sustainable. At the end, it concluded that in different factors such as time of execution, load capacity, flexibility, reducing waste, cost and energy efficiency, plastic bottles can be more effective compared to some conventional building materials such as brick and concrete blocks. By filling the PET bottles with different filling materials compression strength is determined, from which best filling material can be known. Cubes of size 300 mm were prepared by placing the PET bottles in three different layers in different pattern and compression strength is determined, from which best pattern for bottles arrangement can be known. Freezing and thawing test has been performed for continuous 56 cycles and 4-hour fire resistance test is performed on a specimen of size 300x300x100 mm having 3 PET bottles in its core to know the Durability aspect.
