FINENESS TEST OF CEMENT BY BLAINE'S AIR PERMEABILITY

The aim is to determine the fineness or surface area per gram of the cement. PRINCIPLE The fineness of cement is measured as specific surface. Specific surface is expressed as the total surface area in square meters of all the cement particles in one kilogram of cement. The higher the specific surface is, the finer cement will be.

FINENESS OF CEMENT ENGINEERS ENGINE

Fineness of cement has a great effect on the rate of hydration and hence the rate of obtaining the strength of concrete. Finer cement offers a great surface area for hydration and hence faster the development of strength. 6. Increase in fineness of cement also increases the drying shrinkage of concrete and hence creates cracks in structures.
