ASTM C204 outlines the procedure to determine the fineness of hydraulic cement using the Blaine air-permeability apparatus. Fineness is expressed as the total surface area in square centimeters per gram (or square meters per kilogram) of cement and is an important factor influencing the hydration rate and strength development of the cement.
This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface …
— The surface area, called the Blaine fineness, is expressed in units of cm 2 /kg. The Blaine fineness of PC usually ranges from 3,000 to 5,000 cm 2 /g. Determining relationships between the chemical ingredients and Blaine fineness is still an important research topic for cement and concrete industry.

— Blaine's air-permeability experiments. Blaine's method is based on the fact that the air permeability of a packed bed of particles is proportional to their fineness and therefore the SSA. The value measured during testing is the time required to pass a certain volume of air through a packed bed of solids with given size and porosity.
