surface area of cement mill

Specific surface area of cement - Low Price Microsilica ...

It is represented by square centimeters per gram (cm2/g) or square meter per kilogram (m2/kg). The specific surface area of the cement is related to the fineness of the cement. The thinner the cement grind, the larger the specific surface area, and vice versa. The specific surface area of cement is

The BET-specific surface area of hydrated Portland cement ...

2003-12-1  In addition to C-S-H, Portland cement and some related binders in their hydrated state may contain calcium hydroxide (whose specific surface area is negligible) and variable but usually small amounts of ettringite (C 6 AS 3 H 32) and/or monosulfate (C 4 ASH 12). The latter two phases decompose under D-drying conditions but barely retake any of ...
