| Abstract |
With the introduction of modern materials, such as cement and concrete, the use of traditional lime(aerial lime) have decreased. Traditional
lime manufacturing and its construction methods have been cut off in Korea. However, modern materials being used at the site of repair and
restoration of cultural heritages, not only heterogeneity but also secondary damage is induced. Therefore this study aims to reproduce
traditional lime with added perilla oil to confirm the possibility of improving the performance of traditional lime through the characteristics
of aerial lime. Aerial lime plaster specimen containing perilla oil was prepared by securing evidence from the ancient literature, and its
characteristics were investigated. The addition of perilla oil revealed that the advanced workability of the flow value declined. However, only
a small amount of perilla oil gave discoloration to the aerial lime specimen. It is necessary to control the amount of perilla oil used when it
is applied to the conservation and restoration of historical sites. Through the neutralization test and the μ-CT analysis image that carbonation
of aerial lime was delayed due to the addition of perilla oil. Additionally perilla oil imparted water resistance. Since freezing-thawing of
water is the main cause of damage to aerial lime materials, the performance improvement of aerial lime can be expected by adding perilla
oil. |
