| Summary: | 博士 === 國立交通大學 === 土木工程系 === 89 === In this research the Synchrotron Radiation Accelerator (SRA), Nuclear Magnetic Resonance (NMR), Thermal Stimulated Current (TSC) were applied to analyze the hydration behavior of cement with pozzolanic materials. The complicated procedures such as making vacunm, drying and sputter coating are unnecessary for tested specimens. In other words, during the research the specimens under absolutely normal situation were studied proceeding the whole hydration inspection and evaluating the chemical ingredients. This sutdy indicates SRA could be used for both the qualitative analysis and the quantitative analysis of the crystal structures such as Ettringite (AFt), Monosulfoaluminate (AFm) and Ca(OH)2. Using SRA to measure hydration degree is one feasibile method . Especially , the hydration in initial stage can be detected .
