Fineness Test of Cement; Its Apparatus, Procedure.

Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1. Sieving Method. 2. Air Permeability Method Blaine Method .

Cement - Wikipedia

Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is only behind water as the planet& 39;s most-consumed resource.
