Research Abstract	In this study, fundamental data of the carbonation behavior of C-S-H with various Ca/Si ratio were obtained. A part of C-S-H (Ca/Si ratio = 0.7, 1.1 and 1.4) were not decomposed, while the pH of solution decreased to the equilibrium value. The lower Ca/Si ratio, the more the C-S-H was not decomposed due to carbonation.
