In the presented work, the results are provided of examining the properties of a pore solution during the process of cement paste hardening. Based on the experimental data of W. P. Halperin et al, the evolution of the mass balance of structured physical water is analyzed as a combination of interactions of capillary, gel, and other components. The formation and development have been studied of the pore solution viscosity. The comparison of the reported dependences of the water viscosity on the size of the pores with the experimentally determined values of the pores’ radius has allowed estimating the rise of avid the pore solution viscosity in the process of hardening of cement paste. The separation of the structured pore solution’s viscosity into capillary and gel components allows for a quantitative and qualitative consideration of the cement paste hardening as the process of forming a macrocapillary matrix, inside which a microporous structure is formed of the cement gel.
