Significance of Fineness of Cement:
- As we know that the Bleeding phenomena reduce by increasing the fineness of the cement because of an increase in the surface area & adsorb water content.
- An increase in fineness, an increase in hydration heat because of an increase in the surface area of cement, requires more water content.
- Suppose particles are of small size. It’s surface area increase. This adhesion between them is increased.
- By the increase in fineness, the surface increases. Hence, it requires more water, and if calculation is not done properly, then dry shrinking possible to occur in concrete structures.
