摘　　要：水泥基修补材料和高分子修补材料与古迹本体材料存在相容性问题,不利于古迹的修复工作。糯米-石灰砂浆是中国古代传统的一种建筑材料,拟挖掘并提升其性能用于古迹的修补。分别采用石灰石粉、粉煤灰和矿粉等微米级掺和料与硅灰复合,研究微纳米掺和料对糯米-石灰砂浆强度的影响。试验研究的结果表明,微纳米复合掺和料提高了糯米石灰砂浆的力学性能。这种材料与中国古代建筑材料相容,可用于古迹的修复工作。Portland cement and polymers have low chemical and physical affinity for traditional building materials .This hinders the restoration of historical buildings .Glutinous rice-lime mortars （GLM ） used in construction since ancient times in China were recov‐ered ,and attempts were made to enhance their performances .Micron particles ,such as limestone ,fly ash and slag ,with silicon fume contained nano-particles were selected on the basis of their properties .Flexural strength and compressive strength of GLM with micron-nano-particles were measured .Test results show that the mechanical performances of newly-designed traditional GLM were improved .And they are compatible with ancient building materials in China ,so it can be used in the restoration of architectural heritage .
