Material testing facilities

The material testing facilities of CBER include those for the determination of physical and durability properties of materials as well as simulated weathering and corrosion tests.

  • Two programmable weathering chambers of 1 cubic metre capacity, for cycling temperature and humidity.
  • An accelerated carbonation chamber of 0.6 cubic metre capacity, with microprocessor controlled relative humidity, temperature and carbon dioxide concentration levels.
  • A salt spray chamber, capable of operating a continuous or intermittent mist within the chamber, at different combinations of temperature and salt concentration levels .
  • Set up to study the UV weathering of building materials and surface treatments.
  • Set up to study the acid resistance of concrete.
  • Computer controlled instrumentation facilities to monitor
  • corrosion of steel in concrete.
  • internal relative humidity and temperature of building materials.
  • resistivity of building materials
  • Half-cell potential and electrical resistivity apparatus
  • Permeability, absorption and diffusion measurement set ups and equipment.
  • Equipment to determine the abrasion resistance of concrete.
  • Test machines to determine compressive, tensile and flexural strengths of building materials.
  • Near surface methods to determine the compressive/tensile strengths of concrete.
  • Ultrasonic pulse velocity tester.
  • Apparatus to determine the impact and crushing strength values of aggregates.
  • Equipment to determine the particle size distribution of aggregates.
