Types of Cement

There are 27 types of common Cement which can be grouped into 5 general categories and 3 strength classes: ordinary, high and very high.  In addition, some special Cements exist like sulphate resisting cement, low heat cement and calcium aluminate cement.

The most commonly used cement types for general construction work are:

  • Ordinary Portland Cement (OPC):  32.5, 42.5, 52.5 grade (OPC)
  • Portland Pozzolana Cement (PPC):  Both Fly Ash and Calcined Clay based
  • Portland Slag Cement (PSC)

Special cements are cements that are manufactured for specific applications where normal cements may not be able to perform satisfactorily. Some of the special Cements that are commonly used are:

  • White Portland Cement
  • Sulphate Resisting Portland Cement (SRC)
  • Rapid Hardening Portland Cement
  • Low Heat Portland Cement
  • Hydrophobic Cement
  • Calcium aluminate cement
  • Masonry or Mortar Cement
  • Oil-Well Cement

Types – ASTM

For Portland Cement types, ASTM C150 describes:

Cement Type  Description
Type I  Normal
Type II  Moderate Sulfate Resistance
Type II (MH) Moderate Heat of Hydration (and Moderate Sulfate  Resistance)
Type III High Early Strength
Type IV Low Heat Hydration
Type V High Sulfate Resistance

For blended hydraulic Cements specified by ASTM C595 the following nomenclature is used:

Cement Type Description
Type IL Portland-Limestone Cement
Type IS Portland-Slag Cement
Type IP  Portland-Pozzonlan Cement
Type IT  Ternary Blended Cement
