| Research Abstract |
Weathering rates and lifetime of building stones along with weathering environment were analysed at Angkor monuments located in sub-tropical environment. In the monuments which were constructed in 7-12th century, weathering rates and physicochemical properties of the building stones were measured in the original position accompanied by rock weathering tests. In addition, weathering environment was measured using data loggers installed in the sanctuary of Angkor Wat temple with meteorological observation. As a result, the weathering rates of 35 points of 29 monuments were 0.7 - 9.2 mm/100 yr. Weathering of the building stones starts with slight physicochemical property change and algae covering in the early stage, then weathering rates reveal strong directional dependence. Lifetime of the building stones is concerned with volume and frequency of wet-dry change.
