The study of Concrete Technology makes use of many test methods not normally associated with Civil Engineering. Methods include those for pore structure and surface area by BET; mercury porosimetry; permeability to vapour, gas, and liquids; mineralogy by optical microscopy x-ray diffraction and thermal analysis; microstructure by optical and electron microscope; and chemical analysis by XRF, AA, IR, IC, or neutron activation. Published literature will be discussed with respect to differences in such procedures, and interpretation of data.
