Abstract

Currently, the development of microstructure in cement pastes and its resistance to harsh environments is of considerable interest. In this study, the effects of cryogenic temperatures on hydrating white cement pastes have been studied using the Nuclear Magnetic Resonance (NMR) techniques. NMR relaxation analysis allowed to interpret the evolution of the micropore structure in a cement paste during hydration, permitting a basic understanding of the state of water and change of pore structure undergoing wet-dry and free-thaw cycles. Pore struction evolution determined by the suppression of the freezing temperature of water has been compared with relaxation analysis. Water consumption, the total specific surface area, and pore size distribution have been measured as a function of hydration times. Furthermore, supercooling and freezing point depression of confined water has been studied systematically.
