摘　　要：研究了中国传统糯米-石灰砂浆的原材料(糯米浆、石灰、红糖浆、河砂和黏土等),并提出了糯米-石灰砂浆的结构模型,该模型刻画了材料的非线性结构。该模型表明,糯米-石灰砂浆的的性能与其结构直接相关,断裂能在其中的分叉和偏转是其强韧化的两个最为关键的要素。糯米-石灰砂浆的微观结构采用SEM和XRD进行分析,测试结果表明:糯米浆和红糖浆对CH碳化反应有一定的影响,Ca CO3的晶粒形貌改变和粒度的减小优化了糯米-石灰砂浆的微观结构。Raw materials observed in ancient glutinous rice - lime mortar in China, such as glutinous rice,lime,brown sugar, fine aggre gate, and clay etc. were investigated in this work.A model was proposed to simulate nonlinear structure in ancient glutinous rice -lime mortar. It was found that the key parameters involved in the model are bifurcation and deflection of fracture energy. The microstructure of glutinous rice - lime mortar were tested by scanning electron microscopic and X - ray diffraction analysis. It was observed that the morphology and size of calcium carbonate were modified by glutinous rice and brown sugar.
