The effect of demolition waste composition on the landfill liner physical characteristic

This study analyses the physical characteristics of demolition waste on the composite landfill liner. In this study, three characteristic composite landfill liner tests consist of swelling/specific gravity, OMC standard proctor determination, and atterberg limit test. Composite landfill liner consists of demolition material, bentonite, and lime with eight variable samples. Based on this research, specific gravity ranges from 1.8-2.1 g/cm3, OMC’s highest is V7, and MDD’s lowest is 1.81 g/cm3. Demolition waste content is below 80% can be carried out atterberg limit test. It is related to the particle size distribution test, which states that the size of demolition waste is a type of sand.
