The purpose of this study is to define chemical substance and constituent mineral of lime plaster of Jinpari Tomb No. 4, which is a Goguryeo ancient tomb wall painting manufactured in the middle of the 6th century, measure physical property and dynamic feature of lime plaster and enable it to be used for study on preservation method, manufacture of preservation agent and experiment of appropriateness. In experiment, white lime plaster layer(M01) sample made of lime and sand and brown lime plaster layer(M02) sample made of clayish soil of weathered rock and lime.
By observing the use of FE-SEM and EDS in detail area and analyzing their substances, it was found that there were lump-typed clayish soil of weathered rock, lime and shell in M01 and M02. It was also found that M01 consisted of Ca and Si and M02 consisted of Ca, Si and elements organizing clayish mineral such as Al and K. Although very fine charcoal was observed, it seemed that it was mixed in the process to manufacture quicklime. XRD analysis was performed in order to define the constituent mineral of lime plaster. It was found that M01 consisted of lime and quartz sand and M02 consisted of lime, quartz sand, muscovite and clayish minerals such as illite and clinochlor. In order to analogize constituent minerals through qualitative analysis on chemical substance of lime plaster, XRF analysis was performed by melting lime plaster sample at the temperature of 1400℃ and manufacturing glass disk. The analysis result showed that it was same as the result of EDS and XRD. From the result of performing qualitative analysis on ionized soluble salt contained in the lime plaster sample by using IC and ICP-OES, it was found that Ca2+ and Cl- were contained as the largest ratio of positive ion and negative ion respectively.
Through physical property of sample, the researcher measured particle size analysis, water vapour permeability, capillary water absorption coefficient, capillary water absorption speed coefficient and total water absorption degree in air & vacuum status. Regarding water vapour permeability, it was measured that the porosity of M02 was larger than that of M01 but the permeability of M02 was better than that of M01. Regarding capillary water absorption coefficient and capillary water absorption speed coefficient, M01 was higher than M02 but regarding absorption degree in air & vacuum status, M02 was higher. In the result of particle size analysis, it was found that M01 mainly contained inorganic additive, whose diameter was 0.063mm and M02 contained inorganic additive, whose diameter was less than 0.063mm.
In the analysis on dynamic feature, the researcher calculated compressive strength by measuring point load strength index. It was found that the compressive strength of M01 was higher than that of M02.
