There were several lime mixtures used for basic materials and wall plastering in building construction in the Joseon Era, one of them is Ocher-Sand Lime(Sammulhoe, 三物灰). It was so excellent one used for Royal Tombs and Palaces. Accordingly, this study aims at figuring out 1) if Ocher-Lime could be applied as modern eco-friendly materials in construction and 2) its performances based on ICOMOS' criteria that 'the parts to be recovered should be done in the scope of specifications and technologies conserved in the time of the construction' in repairing and recovering the building from fire damages, etc. Therefore, ascertaining the materials and mixing rate of Ocher-Sand Lime through the related literature in the Josen Era was conducted, and the experiments on performances for basic and wall plastering materials based on KS testing methods were done as follows: In the experiments, mixing the materials, flow and congelation of the samples before and after hardening, bending and compressing strengths, surface contact angle(water-proofness), permeability, and surface cracking property were tested and analyzed. As a result of the ascertaining, sammulhoe consists basically of lime, sand, and ocher in the ratio of 3:1:1, and is added with elm bark water. For the characteristics of the samples mixed according to the mixing ratio given for the experiments before their hardening, there are some differences depending on conditions of ocher and sand smashed. Congelation time took twice or three times longer than ordinary cement mortar. After hardening, average compressing and bending strengths of sammulhoe ranged in 3~4㎫ and 0.6~0.8㎫, respectively, and it was far weaker than ordinary cement mortar. However, when adding elm bark water, the samples showed some waterproof and permeable characteristics. The surface cracking property was different by their mixing ratio. In order to use traditional construction material, sammulhoe as a modern architecture material, it is necessary to conduct additional ascertaining and research for improving its performances in various areas.
