摘      要：Water stability of soil is crucial to the durability of earthen monuments,especially those located in the humid weather *** paper discusses the selection reason of materials(tung oil and quicklime) for earthen monument treatment,and then validates the applicability of these materials with tests of soil-water characteristic curve(SWCC),aggregate stability test(AST) and scanning electron microscope(SEM).The soil tested was sampled from Da Bao en temple in Nanjing,Jiangsu province,*** test results indicate that the carbonation reaction of quicklime offers a favorable environment for the formation of tung oil ***,the regulatory function of tung oil restricts the crystallinity of calcium carbonate(CaCO3) and forms fine *** treated with both of tung oil and quicklime has good water repellency and aggregate stability without obvious changing in aesthetic *** and carbonation treatment can be applied prospectively in the conservation of earthen monument located in humid weather condition.
