2020-5-8The objective is to reduce the ore in size through various closely controlled stages to that degree of fineness which gives an economic liberation of valuable mineral, but which avoids as much as possible the production of sliming fractions. A different philosophy applies to the crushing and grinding of Gypsum.

2. Increasing the fineness of cement from 2700 to about 4000 cm2g 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 air-entrained concrete is increased by increasing the cement fineness.
