| Summary: | 碩士 === 國立成功大學 === 建築學系碩博士班 === 94 === The stucco on the construction walls of historical building construction in Japanese rule period often faces the problem of material uses. In the past, the idea of Cultural Heritage Preservation Act is that it need for using original or close material to retrofit, but now it can adopt the modern technology and method.
In view of this, this research is drafted with the angle of the material, and test on the stucco mortar on wall by the rate of materials in documents and cases. The item includes three mechanics test: compressive strength, tensile strength, and bond strength , and two physics test: surface and saturated water absorption rate. The purpose of test lies in probing into the characters and rationality of application on motar, and the result of the test will offer the person who retrofit the historic building as reference. The results of research are as follows:
1.The method to mix paste and hemp fiber into the mortar in Japanese rule period has meaning in every strength test display,it will not better to add one of them.
2.Mixing the three materials of Seaweed paste, hemp fiber, and glass fiber into the mortar often displays unideally on strength.
3.Glass fiber can make strength raise among mortar, and do not need to mix with other materials.
4.Hemp fiber and glass fiber mix into the mortar half-and-half display generally good, and can keep the utility of both.
5.Adding or mixing the same material into different mortar perhaps will not present the same character, and it often has unexpected results after mixing.
