在過去的古蹟及歷史建築結構上,由於夯土材料的成本低廉、可重複使用、取得容易、施工簡便可循環使用等特性,故被廣泛使用。古蹟之保存與修復必須維持「修舊如舊」的原則,但其原物料抗潮性低、抗壓性不足、結構鍵結能力差等物性缺失,使建築物易受自然災害,嚴重者甚至造成坍塌,在修復方面也產生極大不便。本研究以「無機聚合物」膠合黃土,進行古蹟、夯土結構修復補強之可行性探討,研究嘗試採用不同的比例之黃土,添加於無機聚合物中,並製成試體進行不同齡期的抗壓強度試驗。另以各種不同比例之飛灰,置換部分變高嶺土,再進行膠結黃土後,探討其抗壓強度,實驗結果發現,與原有夯土結構磚比照,除可增加抗壓強度之外,亦可消除原有夯土磚低耐水性及低強度之缺點。
In the past monuments and historic structures, due to the low cost of compacted earth materials can be reused, made easy, simple construction and other characteristics can be recycled, it is widely used. The reserve and repair of mon-uments should be retained the principle of “repair olds as old”, But the original material its low moisture resistance, resistance insufficient structural capacity and poor bonding properties is missing, so that the building vulnerable to natural dis-asters, serious and even cause the collapse of the repair also have a great incon-venience. In this study, " Geopolymer " cemented loess, carried monuments, res-toration feasibility reinforcement of compacted earth structure discussion, study try using different proportions of the Land, Geopolymer, and specimens were not made of the same age compressive strength trials. After another in a variety of different proportions of fly ash, metakaolin replacement part, then cemented Land explore its compressive strength, the experimental results showed that the original structure of rammed earth brick cf, in addition to increase the compressive strength, but also eliminate the disadvantages of compacted earth brick low water resistance and low intensity of the original.
