조선 후기 성곽 축조에 사용된 석회 모르타르의 재료 및 기법에 관한 문헌연구

Abstract

There was a dramatic change in the construction technology of fortresses in the late Joseon dynasty. Due to the introduction of advanced construction methods and the development of building materials, the main material changed from earth to stones or bricks. In particular, the use of lime mortar is a representative feature of the construction style in this period, compared to the previous period. In this study, the materials and techniques of the lime mortar used in the late Joseon dynasty were investigated based on historical literature. It was found that the type and proportion of lime varied depending on the purpose or time of the construction, possibly to improve the performance of the lime. Moreover, the most preferred material for the masonry was fired brick, but realistically, stones were generally used. Therefore, it was possible to know the difficulty of supplying or preparing the bricks at this time. Lastly, the construction technology of the fortresses was divided into interior and exterior. Accordingly, the lime mortar used in each case was also different. The interior was filled with rubble and Ocher-Sand Compound Lime (三物灰), whereas the exterior was stacked with stone, bricks with the finishing using Starch Compound Lime (水灰). However, there were limitations to find the type and mix proportion of the lime used exactly. Therefore, scientific or experimental research should be conducted in parallel with literature research.
