Optimizing cement strength - Cement Lime Gypsum

Increasing gypsum/SO 3 up to a certain optimum level increases the cement strength development. However, increasing SO 3 beyond that level will decrease the compressive strength and also will cause a cement expansion problem i.e. delayed ettrignite expansion.

Cement Types - Portland Cement Association

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. The heating that occurs in the kiln transforms the raw materials into new chemical compounds. Therefore, the chemical composition of the cement is defined by the ...
