Investigating into utilization of waste plastic in producing unburnt bricks with compressive strength of 7.5 MPa
Abstract
Nowadays, unburnt bricks have been used across the country to replace burnt clay bricks because compared to burnt clay bricks, unburnt bricks have many advantages such as less use of agricultural soil, environmental protection, high automation capability … Besides, plastic waste is currently an alarming problem to the environment not only in Vietnam but also all over the world. Therefore, to solve environmental problems along with improving some disadvantages of unburnt bricks such as large volume mass,… this study is aimed at using waste plastic to replace a part of stone dust in the production of unburnt bricks. The results show that the maximum PET plastic waste ratio must be 12,5% in order to ensure the standard requirements of execution and compressive strength. This study indicates the possibility of reusing PET plastic waste to minimize environmental pollution.
