| Abstract |
According to the standard specifications for repairing cultural heritage, the initial layer of Korean traditional walls requires aging before
application. However, as the detailed method is not specified, craftsmen employ individual approaches, raising concerns about technique
transformation and quality variations. Against this backdrop, this study compares aging methods used in the field to derive an optimal
approach. Four aging methods were employed, including three field methods and one accelerated aging method developed in this study. Wall
specimens were manufactured using these methods, and their attributes were compared through experiments on workability, length change,
crack occurrence, and compressive and bending strength. Results indicate that aging straw with soil decreases wall specimen flowability but
increases adhesion, improving workability. Using aged raw materials alters drying shrinkage and crack patterns without negative effects on
wall performance; compressive strength tends to increase. Overall, aging raw materials effectively enhances traditional wall workability and
strength. Among the aging methods tested, the most effective was the most labor-intensive involving aging soil and straw with water for 3
days, then mixing and aging for 4 days, while the simplest involving boiling straw in water for 30 minutes proved least effective. |
