Abstract

T. C. Powers is a researcher who developed physically and chemically systematic research for the first time concerning the moisture condition of the cement materials. The model expressing the change in the moisture composition accompanying the progress of hydration has been reviewed several times since it was formulated in the mid-1940s by Powers and Brownyard. In this study, water in the cement materials treated as three compositions of “capillary water”, “gel water” and “chemically bound water”. Although Powers et al. had formulated moisture composition for hardened cement paste, but in this commentary, it is expressed as a model extended to concrete.
