Manufacturing Of Cement By Dry And Wet Process

Grinding: The cooled clinkers are finely ground in ball mills or tube mills. Also, the gypsum is added during grinding about 2-4%. The gypsum acts as a retarder and so allows the cement to mix with sand or aggregate and to be placed in position. i.e. it increases the initial setting time of cement.

Soil-Cement

Soil-cement thicknesses are less than those required for granular bases carrying the same traffic over the same subgrade. This is because soil-cement is a cemented, rigid material that distributes loads over broad areas. Its slab-like characteristics and beam strength are unmatched by granular bases. Hard, rigid soil-cement resists cyclic cold ...

Further milling deteriorates penetrability, as illustrated by the red part of the curve. For example, milling cement from a d 95 of 30 µm to a d 95 of 10 µm deteriorates penetrability twofold from a b crit of around 80 µm to 160 µm. The reason is the higher flocculation affinity of the grouts based on fine milled cement .
