Abstract

Stone heritages, such as stone architectures, stone statues, graveposts and stone towers, are generally located outside and they are exposed to the wind and rain. Therefore, they have been defaced and collapsed due to weathering. The main reason of the weathering is the existence and movement of water in the rock heritages, and the appropriate protection method is expected in order to keep heritages in good conditions. Kyusyu Archaeological Laboratory introduced a new method, Aquo-Siloxane Method, in order to protect the stone heritages. In this method, the protection material is painted on the surface of heritages, and the material penetrates into the rock pores. Then the water in the stone structures is captured by the material and it becomes stable. However, the stability of the captured water has been not evaluated quantitatively yet, and the characteristics of Aquo-Siloxane Method also have not been verified yet. In this study, the tests related to the water migration in rock pores, such as water permeation tests, evaporation tests and capillary tests, were applied to the porous rock samples. By comparing the state between with and without protection, the effect of Aquo-Siloxane method was verified. It was found that the water migrations in the pores were restrained in the rock sample once the water was captured by the protection material. The condition when the protection material is painted was also confirmed, and it was found that the protection effect was not influenced by the initial water content of rock samples.
