Fineness Test Of Cement Formula With Table Of Calculation

The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement. The maximum residue after the sieving in standard sieve should be limited to 10% by weight for OPC, and 5% by weight for rapid hardening cement.

Fineness Of Cement By Blaines Air Permeability Method Is

Jun 18, 2014 Coarse cement particles settle down in concrete which causes bleeding. Approximately 95% of cement particles are smaller than 45 micrometers, with the average particle around 15 micrometers. In the early 1900s, cement fineness was expressed as the mass of cement per fractional size (percent weight retained on specific sieve sizes).
