Determination of Fineness of Cement by Sieving

Jan 31, 2021For ordinary Portland cement, the specific surface area should not be less than 2250 centimeter square per gram. Checking fineness of cement through sieving is an indirect method and it is easily done in the laboratory. The specific surface area of cement can be measured by Blaine's Air permeability of the cement apparatus. ALSO READ

Blaine fineness values for Type III cement range from about 500 to 600 m 2 /kg. Type I cement Blaine fineness values range only from 300 to 400 m 2 /kg [46] [47] . Although the fineness of Type III cement provides a much greater surface area for the hydration reaction, it also may require a little more water to coat the particles.
