Occurrence of thaumasite in deteriorated concrete
AbstractThe first case histories of thaumasite in concrete products in the United States were identified by the writer in the 1960s. There included two underground sanitary pipes, a grout in an underground lead/zinc mine, and the bottom of a concrete pavement on grade. In these cases, thaumasite was first identified by optical properties in powder mounts in a petrographic microscope, then further confirmed by X-ray diffraction and characterized in an electron microscope. Morphological similarities and positive distinction between thaumasite and ettringite are considered.
