The normal consistency was related with a series of aspects. On one hand, the Blaine surface area influenced the normal consistency. Higher surface area of cement particles might lead to higher water demand. Besides, the adsorbed PCE-type GA onto the surface of cement particles affected the water demand as well as the normal consistency.

May 29, 2019· What Is Fineness of Cement. The fineness of cement is a measure of cement particle size and is denoted as terms of the specific surface area of cement.. The Fineness Test of Cement is done by sieving cement sample through standard IS sieve. The weight cement particle whose size greater than 90 microns is determined and the percentage of retained cement particle are calculated.
Jan 02, 2018· The fineness of cement is tested by measuring the air permeability specific surface area of the cement powder. The measurement of fineness of hydraulic cement is undertaken with the Blaine air-permeability apparatus to determine the specific surface expressed as the total surface area in square centimetres per gram (or square meters per kilogram).
