Cements may be used alone (, "neat," as grouting materials), but the normal use is in mortar and concrete in which the cement is mixed with inert material known as is cement mixed with sand or crushed stone that must be less than approximately 5 mm ( inch) in size. Concrete is a mixture of cement, sand or other fine aggregate, and a coarse aggregate that for most ...

The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

Applied to clinker, it is calculated as: LSF=CaO/ ( 2 + 2 O 3 + 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker. A clinker with a higher LSF will have a higher proportion of alite to belite than will a clinker with a low LSF.
