| Abstract | 壁畫空鼓是莫高窟第85窟的主要病害之一,針對空鼓壁畫的具體特征,選擇多種充填材料,以不同配比配制的81種灌漿材料,經過性能測試及現場模擬試驗,最終篩選出了以澄板土(一種當地河床沉積黏土)為主、摻加適量浮石和玻璃微珠作為充填劑,水中加適量蛋清為主劑配制的灌漿材料。這種漿液具有容重小、流動性好、結石體透氣性好、收縮率小、黏結強度適中并且可調等特點。現場試驗表明,這種材料是莫高窟第85窟空鼓壁畫灌漿加固的理想材料。
Detachment was one of the most critical problems affecting the Cave 85 murals at the Mogao Grottoes.According to the actual characteristics of the detached murals,81 grout formulations were tested.A number of materials with potentially useful properties were identified and assessed,and tested both in the laboratory and in detachment simulation experiments.A mixture of denbantu(an earthen sediment of the local river),pumice,glass microspheres,and water was eventually selected for the optimized recipe.Among the most advantageous performance characteristics of the mixture were low density,minimal shrinkage,moderate and adjustable cohesive strength,and compatible water vapour permeability.It also had excellent working properties,such as good fluidity.The in-situ experiments demonstrated that the mixture was an excellent grouting material for the detachment problem in Cave 85 at Mogao Grottoes. |
