Fineness Test on Cement. Fineness of cement particles may be determined either by sieve test or by permeability apparatus test. In sieve test, the cement weighing 100 gm is taken and it is continuously passed for 15 minutes through standard BIS sieve no. 9. The residue is then weighed and this weight should not be more than 10 per cent of original weight.
Fineness (= surface area / weight): This test determines the average size of cement grains. The typical value of fineness is 350 m 2 / kg for Type I Portland cement. Fineness controls the .
Civil At Work: To Determine The Fineness Of Cement By Dry ... · Cement is obtained by granding the various row material. The degree to which the cement is drawn to smaller and smaller particals is called fineness of cement.
HMKC1 Blaine Apparatus is a cement testing apparatus used to determine the particle size of portland cement, limes and similar powders using the Blaine airpermeability method. It gives accurate and repeatable test results of cement specific surface area.
Phoenix Cement® Rapid Power™ Type III (LA) meets all chemical and physical requirements of the current ASTM Specification C 150 for Type III Low Alkali Portland Cement and C 1157 HE, High Early Strength cement, as well as the requirements for Type III (HS).
fineness of cement measured in m^2/kg; measured using Blaine's air permeability apparatus or Wagner's turbidimeter results always reported based on test conducted; normal fineness = 300400 m^2/kg; highearlystrength fineness = 500600 m^2/kg. SSA and strength relationship.
The Blaine air permeability apparatus is used to determine the fineness of Portland cement in terms of the specific surface expressed as total surface area in square centimetres per gram of cement. In accordance with GB 8074 and ASTM C204.
IV/ CONCRETE TECHONOLOGY LABORATRY (4CE8A) Experiment Object: To determine the fineness of cement by sieving through a 90 micron IS Sieve. Necessity: To represent/correlate with specific surface area of cement and to check the proper grinding of cement.

Portland cement. Clinker size directly affects the thermodynamics of the chemical reactions required for setting and curing characteristics. Cement that is too fine can react quickly causing excessive heat evolution and expansion of the cement/concrete. As cooling occurs, the concrete can then become unstable and crack or loose strength. If cement
