  • What is residue and Blaine in cement? - Quora

    2019-07-26  The Blaine of cement refers to the fineness of its particles and is expressed as (m2/kg) Low heat cement might would typically have a Blaine of 250 m2/kg while standard Portland cement (CEM42.5) could have a Blaine in the range of 300–350 m2/kg and rapid hardening cement (CEM52.5) could have a Blaine in the range of 400–450 m2/kg.

  • Fineness Test of Cement; Its Apparatus, Procedure.

    Now put the values in the formula; % of retained weight of cement = (65/1000) x 100. SO, the result of a fineness test of cement will be 6.5 % which is below the IS value (10%) and hence cement is in good condition. Thanks for reading this article.

  • Air permeability specific surface - Wikipedia

    The air permeability specific surface of a powder material is a single-parameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder. The SI units are m 2 kg −1 ("mass specific surface") or m 2 m −3 ("volume specific surface").
