### Factors Affecting the Shrinkage of Concrete Concrete

The quality of cement pate is dependent on the water cement ratio. Higher the w/c ratio greater the shrinkage thus it can be said that for a given aggregate content the shrinkage of concrete is a function of the water-cement ratio. The effect of water-cement ratio on the shrinkage is shown in Fig. 16.8.

The 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 cement.
