FINENESS OF CEMENT BY BLAINES AIR PERMEABILITY METHOD .
Jun 18, 2014· In the early 1900s, cement fineness was expressed as the mass of cement per fractional size (percent weight retained on specific sieve sizes). Now a day's fineness is usually measured by the Blaine airpermeability test that indirectly measures the surface area of the cement particles per unit mass.
Guidelines for Selection of Quality Construction Material
Aug 26, 2015· Choosing the correct quality of construction materials can sometimes prove to be difficult. Some of the critical construction materials like cement, steel, concrete etc. need to be of the highest quality as these are the essential "backbone" of any construction endeavor. The suitability of these materials for construction purposes can be established through rigorous testing.

2. Increasing the fineness of cement from 2700 to about 4000 cm2/g reduces the water requirement of concrete. Increasing the fineness of cement beyond an optimum limit increases the water requirement of concrete. 3. The workability of non airentrained concrete is increased by increasing the cement fineness. In airentrained concrete the effect of fineness of cement on workability is very much less pronounced. 4.
