Rehabilitation of a structure requires an in-depth knowledge of the nature and extent of the problems affecting the structure of the materials. Laboratory testing is often an essential step in establishing a plan for remedial action.

  2. The CONCRETE laboratory specialises in characterising materials (concrete, steel, masonry) and investigating pathologies:

    • Optical microscopy (transmitted and reflected light)
    • Scanning Electron Microscopy (SEM) with elemental microanalysis
    • Metallographic examination
    • Mineralogical analysis by x-ray diffraction
    • Chemical analysis by atomic absorption
    • Pollutant content determined by ionic chromatography
    • Fourier Transform infra-red spectroscopy (FTIR)
    • Thermogravimetric analysis (TGA)
    • Density porosity accessible to water, permeability to water and gas (CEMBUREAU)
    • Accelerated ageing test, freeze-thaw resistance test
    • Resistivity and apparent and actual chloride diffusion coefficient
    • Mechanical tests (compression, tension, Young’s module)
