Evaluation of environmental degradation factor of the ceramic sidings

Abstract

In this research, the outdoor exposure test was conducted to examine the climatic loads depending on the directions and the areas of materials. Two different specimens for the exposure test were built in Asahikawa and Tsukuba. In this paper, the degradations of 2 years exposure test were discussed, focusing on the effect of moisture behavior and the wet condition of the walls. From the results, it is confirmed that the moisture content at the surface of the wall was brought by rain. Furthermore, the moisture at the surface was calculated by the method of Dr. Ishikawa with standard meteorological data in each region.
