Cement Types - Portland Cement Association

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.

Incorporation of waste materials into portland cement ...

Portland cement clinker is produced from high temperature firing and grinding of mineral deposits such as limestone and clay; the clinker is then ground with gypsum to make cement. Portland cement clinker contains four primary phases: Ca 3 SiO 5 (C 3 S Footnote 1), Ca 2 SiO 4 (C 2 S), Ca 3 Al 2 O 6 (C 3 A), Ca 4 Al 2 Fe 2 O 10 (C 4 AF) .

In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s.
