Fineness 95% of cement particles are smaller than 45 micrometer, with the average particle around 15 micrometer. Fineness of cement affects heat released and the rate of hydration. More is the fineness of cement more will be the rate of hydration. Thus the fineness accelerates strength development principally during the first seven days.
