| 摘要: |
| 采用扫描电镜、X射线衍射、傅里叶变换红外光谱等技术手段，初步探讨了桐油灰浆的材料配方和理化性能，为其在古代建筑、船舶等文化遗产保护中的应用提供理论依据.结果显示，用Ca(OH)2和熟桐油制备的桐油灰浆综合性能最佳，其90d抗压强度和剪切强度较普通石灰浆分别提高了72%和245%，吸水系数仅为普通石灰浆的1/620，抗氯离子侵蚀能力和耐冻融循环等性能均大大改善；该桐油灰浆的优良性能源于桐油的强固化能力以及桐油与Ca(OH)2反应形成的致密结构. |

| Abstract: |
| The recipes and properties of tung oil lime putty were investigated by means of scanning electron microscope(SEM), X ray diffractometry(XRD) and Fourier transform infrared spectrometry (FTIR). The results show that the putty prepared with tung oil and Ca(OH)2 has the best properties. Compared with the common lime mortar, the 90 days compressive strength and shear strength of the tung oil Ca(OH)2 putty increase by 72% and 245% respectively and the water absorption coefficient reduces to 1/620 of that of the common lime mortar. The excellent performance of the tung oil Ca(OH)2 putty can be explained by the strong ability to cure of tung oil and the dense microstructure of the tung oil Ca(OH)2 putty. |
