Abstract:
A need exists to evaluate the condition of the concrete in a structure whenever a question is raised regarding: (1) the significance of visible evidence of changes, such as cracking; (2) the suitability of the structure for rehabilitation, adaptive reuse or enlargement or extension; or (3) the future uses of structure. Such evaluation may involve visual examination, in situ nondestructive testing, sampling, and laboratory evaluation of these samples. Laboratory examination techniques include the polarizing microscope, x-ray diffraction, chemical tests, and physical tests. *
