A coarser-ground cement (250 to 280 m 2 /kg, Blaine) tends to produce lower early strength than conventionally ground cement (320 to 400 m 2 /kg, Blaine) and may affect the workability and bleeding of the concrete. Higher fineness (exceeding 400 m 2 /kg, Blaine) tends to in- crease early strength development and reduce bleeding.
A poll was conducted with members of ASTM C01.25 on Cement Fineness on the materials characteristics for the new 114 cement. The Committee consensus was for a Blaine fineness around 400 m2/kg and +45 𝜇m residue between 4 % and 6 %. A unit of SRM 114r consists of 20 glass vials with plastic caps containing powdered cement.

As a characteristic of cement strength, it is widely used in the cement industry (Company, 1999, Hunger and Brouwers, 2009). The important advantages of Blaine's method are the high testing speed, low cost of the equipment (Blaine meter), simple testing procedure and the small amount (a few grams) of material required for testing.
Above 0.60%, alkali changes of 0.1% can be significant. If the cement is quite low in alkali – say 0.30% – even a 0.05% alkali change can be important. It is impossible to say that such variation will definitely have an effect, but just by tracking it you can judge whether adjustment is necessary.
