Abstract

According to historical records from the Joseon Dynasty, Korean traditional admixtures were made by boiling a mixture of grain powder and water. While the Standard Specification for Cultural Heritage Repair recommends using these traditional admixtures to enhance the workability and adhesion of mortar, it doesn't specify the exact mixing ratio or manufacturing process. This lack of clarity results in inconsistent quality of the admixtures. Without intervention, the techniques for making traditional admixtures could change or disappear altogether. To address this issue, this study aims to develop a method for consistently producing traditional admixtures. Experts were consulted to quantitatively document the manufacturing techniques of four types of admixtures known as Gyomal, Jinmal, Jukmi, and Taemal-based. Analysis of these techniques revealed three factors contributing to quality variation: water content of raw materials, tools used, and dilution method. Three methods were then proposed to mitigate these variations, which were tested through experiments. Results confirmed that each factor indeed influenced quality variation, and implementing all proposed methods simultaneously eliminated errors completely. In conclusion, this study identified quality variation issues with traditional admixtures and presented effective solutions to address them.
