But as the time goes by, especially the environment in Taiwan is with high moisture and frequent earthquakes, these reasons cause the damage of brick structures. Because of lacking for the study of traditional brick structure on mortar, it is important to establish the relevant data about traditional mortar material. This paper studies related characteristic of mortar material of Taiwan traditional brick buildings and expects the analysis conclusion for reference on repairing traditional buildings in the future. In this study, accelerated carbonation equipment and CO2 were used to increase the carbonation rate of traditional Chinese mortar and shorten the curing times. The relationships between compressive strength, bond-shear strength and other characteristics of the materials were also investigated. After curing under a controlled CO2 atmosphere, the traditional Chinese mortar is considerably stronger (23.5~47.7 times stronger in compression, 4.8∼5.8 times stronger in shear) than those cured naturally and the maturation time can be shorten from 3∼4 years to 12∼35 days. Furthermore, the instruments were used to analyze the known composition of the traditional Chinese mortar, such as “energy dispersive X-ray spectrometry (EDS)”, “X-ray diffraction (XRD)”, “X-ray fluorescence (XRF)”, “thermo-gravimetric analysis (TGA)”. Then contrast the result with the known composition. The conclusion shows if integrating the result of XRD, XRF and TGA, it is possible to find out the main composition of the traditional Chinese mortar with these instruments.
