摘　　要：采用FTIR,XRD,SEM等技术,对皖南牌坊上的传统灰浆材料配方进行了初步研究。结果表明,牌坊灰浆样品为石灰掺桐油或糯米而形成的有机-无机复合材料。桐油灰浆强度的形成主要源于灰浆中石灰的碳化反应、桐油与氧气的交联反应和Ca2+与—COO-的配位反应以及由此而形成的致密片层状有机-无机复合结构。糯米淀粉对灰浆碳化过程的调控作用而形成的细密的微观结构是糯米灰浆具有良好性能的微观解释。The traditional lime mortar was investigated by means of scanning electron microscope （SEM）, X-ray diffractometry and Fourier transform infrared spectrometry （FTIR）. The results show that the mortar ~mm the memorial archway in the south- ern Anhui province was the organic-inorganic composite materials composed of lime with tung oil or sticky rice. It was found that the excellent performance of the turtg oil-lime mortar can be explained by the compact lamellar organic-inorganic composite struc- ture that was produced by carbonization reaction of lime, cross-linking reactions of tung oil and oxygen and complexing reaction of Ca2＋ and --C（X） . The compact micro-structure of sticky rice-lime mortar, which was produced due to carbonation process of lime controlled by amylopeetin, should be the cause of the good performance of this kind of organic-inorganic mortar.
