Concrete and Building Materials Laboratory
In this laboratory, experiments related to building materials and concrete are conducted. The major focus is on the undergraduate level training. The lab is also used for research studies by graduate students and annually about 2 to 6 students make tests on concrete samples in various sizes (cubes, cylinders and small beams, structural beam elements). Below there is a list of the equipment and the tests conductible in this lab,
Research equipment:
- Los Angles Abrasion Machine to determine the abrasion percentage
- Electric Furnace in different volumes to heat up materials
- Concrete and other materials Mixers in different volumes
- Concrete Cutter Equipment
- 200 and 300 Ton Press to determine the compressive strength of concrete, brick and other materials
- Furnace to dry up materials
