Investigation of the conservation- treatment methods of the Dutch national monument: the role of microscopy

摘要

The Dutch National Monument in Amsterdam, a World War-II memorial structure, was built with an outer face consisting of slabs of travertine. In 1995, the masonry structure forming the core of the monument showed severe deterioration. In order to determine the actual cause of deterioration and to advise on the most suitable method of restoration, an extensive investigation was carried out on the monument itself and on samples removed from it. The action of frost was found to be the primary cause of the deterioration to the brick structure.
