Abstract
Moisture adsorption-desorption properties of finished wall were examined according to JIS A6909 “Coating materials for textured finishes of building” in case of adding diatomite to stucco or to gypsum on site. Specific surface area and pore size distribution of the finished wall were also measured. Increase of volume for meso-pores was observed and remarkably high moisture adsorption-desorption properties were obtained in case of adding functional diatomite or granular diatomite.
