Study on Deterioration Process of Magnesium Oxychloride Cement under the Environment of Dry-Wet Cycles.To reveal the deterioration process of magnesium oxychloride cement (MOC) in an outdoor, alternating dry-wet service environment, the evolution of the macro- and micro-structures of the surface layer and inner core of MOC samples as well as their mechanical properties and increasing dry-wet cycle numbers were investigated by using a scanning electron microscope (SEM), an X-ray diffractometer (XRD), a simultaneous thermal analyser (TG-DSC), a Fourier transform infrared spectrometer (FT-IR), and an microelectromechanical electrohydraulic servo pressure testing machine.
