Unit for Waste Mechanics

Category: Laboratoriji

The Unit for Waste Mechanics has modern equipment for conducting geotechnical laboratory research work on inert and non-toxic waste samples and for field measurement of landfill gases. Research is mostly conducted according to American (ASTM) standards and it is done on disturbed and compacted waste samples for the purpose of determining basic geotechnical, hydraulic and mechanical parameters.

The Unit for Waste Mechanics participates in the teaching activity by conducting research needed for bachelor, master and doctoral theses.

The Unit for Waste Mechanics also participates in scientific and research projects which are financed by different sources and it also offers laboratory testing services to external users.

We own the following devices:

Devices for determining the basic geotechnical parameters:
- dryers
- sieve sets for determining granulometric waste composition
- muffle furnace for determining organic matter content
- water pycnometer for determining waste particle density
- vibration tale determining the maximum possible compaction of a waste sample
- device for a Proctor test
- device for a CBR test
- sand bath
- waste mill (up to 6 mm grain size)

Devices for determining compressibility parameters:
