Cement Testing Equipment and Techniques
The Blaine Air method is often used to determine the finesse of hydraulic cement. These apparatuses help to determine if the cement is suitable to be used. A mixture's finesse has an important bearing over the rate of hydration, rate of evolution of heat as well as the rate of grain of strength.
