초록

The bricks in Myung Dong Cathedral Church are now deteriorated by the weather such as temperature, humidity, and winds. Thus it is necessary to replace the old bricks to the restored bricks for the load bearing capacity as well as to prevent the penetrations of rains from outside. However the mortar composition is not well defined at this moment and there are literary about the mortar completions. Thus it is necessary to verify the mortar compactions between old bricks and results to bring the restoring the mortar for the replace of new bricks. The particles of mortar was collected from Myung Dong Cathedral Church and particle size was analyzed by the mortar and pestle and mechanicle floater. The X-ray diffraction and XRF of each particles are analyzed. The quartz and feldspar such as albite, kaolinite are observed in large particles(>1mm). However, the clicite was observed at lower than $43{\mu}m$ particles. In XRF analysis, the $SiO_2\;and\;K_2O$ are observed at large particles$(1mm-208{\mu}m)\;and\;CaCO_3$ is observed at small particles$(208-43{\mu}m)\;and\;CaCO_3$ is observed at small particles($208-43{\mu}m$). This is well coincide with XRD results. The optimum volume ratio of lime mortar would be 1: 2 ($CaO: SiO_2$).
