Portland and geopolymer cement mortar moldings were heated from one direction, and the moisture migration and temperature distribution changes on the surface of the moldings were comparatively analyzed mainly using a hyperspectral camera and a thermographic camera. It was revealed that the temperature and the amount of dehydration at which the amount of moisture on the surface of the molded body increases or decreases, moves inside, and dehydrates by clarifying the relationship between reflectance and temperature. Analysis results of hyperspectral camera and thermographic camera indicated that different thermal behavior between Portland and geopolymer cement mortar moldings.
