Study on application of waste plastic in the construction industry

Abstract

Rapid population growth and urbanization require building extra infrastructures, such as housing, health care, and education, all of which require more materials. Recycling waste from nature, industry, and agriculture into construction materials appears to be a possible solution to pollution and the cost-effective construction design challenge. Furthermore, using waste in brick production can help to conserve natural resources, protect the environment, preserve land for development, and provide a cost-effective solution for designing green structures. This study aims to investigate the possibility of using plastic brick as a building material. Molten waste plastics such as low-density polyethene (LDPE) are used to make the bricks. In comparison to conventional brick, the manufactured bricks have good heat resistance and smooth finishing, negligible water absorption, and adequate compressive strength to meet the increased demand for traditional construction materials.
