Elucidating the Effect of Water

2020-1-13The hydration of cement is often modeled as a phase boundary nucleation and growth (pBNG) process. Classical pBNG models, based on the use of isotropic and constant growth rate of the main hydrate, that is, calcium–silicate–hydrate (C–S–H), are unable to explain the lack of any significant effect of the water-to-cement (w/c) ratio on the hydration kinetics of cementGet price
