ANSWER In simple terms, the "blaine" is a measure of the particle size or fineness of cement.
You can control the blaine of cement, which is simply the fineness of the cement mixture, by calculating it with an automatic air permeability test during production.
Blaine is a unit of surface area used to measure fineness of grind in materials like cement. There is no direct conversion from Blaine to microns as Blaine measures surface area while microns measure particle size. The relationship between Blaine and particle size can vary depending on the material being measured.
cm2/gram or M2/KG
unit weight of cement, Portland is 1506 kg/cu.m unit weight of cement, mortar is 2162 kg/cu.m cement, slurry is 1442 kg/cu.m
Blaine fineness is a measure of the fineness of cement or other powdered materials, expressed in terms of the surface area in square centimeters per gram (cm²/g). It is typically determined using a specific air permeability test, which reflects how finely the material is ground. A common standard for Blaine fineness is that a cement with a Blaine value of around 300 m²/kg corresponds to a mesh size of about 90-100 microns. However, the exact mesh equivalent can vary depending on the material and the testing conditions.
as unit weight of cement varies from 830kg/cu.m-1650kg/cu.m volume of cement of 50 kg. varies 0.060241cu.m to 0.030303cu.m if the cement is port-land cement unit weight would be 1440kg/cu.m then the volume would be 0.034472 cu.m
1440kg/m3
Blaine fineness is a measure of the fineness of a powder, typically used for cement and other materials. It indicates the surface area in square meters per kilogram and does not directly convert to microns. However, a general approximation suggests that 3500 Blaine corresponds to a particle size of about 10-15 microns.
