Jul 29, 2020· Fineness of Cement: It is the property of cement that gives an idea about the size of particle in cement and thus surface area ratio. Significance: 1) Increase in fineness, increase in heat of hydration. This is due to an increase in surface area of cement requires more water content. 2) Bleeding reduces by increasing the fineness of the cement.
Determination of Fineness of Cement by Specific Surface by Blaine Air Permeability Method (as per IS ): The determination of specific surface of cement is a recent development. It is a very accurate method of determining the firmness of cement, which affects the hydration and strength development of cement.
