Business Trip to Cambodia
We surveyed the deterioration of the stone ruins of the Angkor Wat temple complex in Cambodia July 24 to 28. In the Ta Nei ruins, we used a new sandstone material similar to that used in the ruins and continued to survey the influence of microorganisms on the erosion of the stone by letting microorganisms flourish on the surface of the new material. The section of the stone with abundant lichen was coated with chemicals to try cleaning, and both positive and adverse effects were observed. We collected fundamental data concerning this research and study at the local site and carried out a construction experiment. We also assisted with the experiment in cleaning microorganisms on the surface of stone at the Western Prasat Top, where the National Research Institute for Cultural Properties, Nara did research, and collected data concerning the cleaning.
