Fineness of cement The fineness of a cement is a major factor influencing its rate of hydration, since the chemical and physical processes involved occur at its interface with water. Portland cement (BS EN 197-1 strength class 42.5N) is usually ground to a surface area of 330–380 m2/kg and rapid hardening (strength class 52.5N) to 400–450

What are the differences in these cement types and how are they tested, produced, and identified in practice? In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.

Fineness of cement increases the rate of evolution of heat. Finer cement offers a great surface area for hydration and hence faster the development of strength. Increase in fineness of cement also increases the drying shrinkage of concrete and hence creates cracks in structures. Excessive fineness requirement increases cost of grinding.
