| Title |
Study for cause of building stone contamination and elemental analysis of contaminant compound. |
| Abstract |
Granite has its own natural beauty, and it has widely used as building cladding, flooring material of the ground, and stone art etc.However, various types of contamination on the granite have been developed and become a serious problem. The main contamination is caused by chemicals(sealant, detergent, spreading chemical for protection of the backside stone surface from mortar). And the other types of contamination on the surface granite come from undesirable carrying out and mis-handling of the stone by workers during construction.This project was designed to solve the problems by understanding the contamination mechanism of the granite as a building material through qualitative analyses(X-Ray Diffraction, Energy Dispersive Spectrometer, Scanning Electron Microscopy) of the contaminated surface sample of the granite. |
